Best Weld Practices
and Weld Process Controls:
  
My
name is Ed Craig. Many
of you will know me from the 18 years I wrote the QA weld column in the USA Weld
Design and Fabrication magazine or perhaps you read one of my forty published
articles on the simplification of weld process controls. If you have a Machinery Handbook gathering
dust on you shelve, I wrote the weld section. I have written four books on weld
process controls and with 45 years of weld process control expertise, I have resolved
manual and robot weld issues in more than a thousand companies in twelve different
countries. I
hope you enjoy the world's largest web site on manual
and robot, MIG, TIG and Flux Cored, Best Weld Practices
& Weld Process Controls: In 2009 I found a process called TIP TIG which is the natural evolution of the seventy year old TIG process, so instead of early retirement I am going to esure America becomes aware of one of the worlds most important weldding processes.
June
12. 2009. Welcome to the first real practical advance in North American
weld
technology in the last three decades, the patent pending TIP TIG process.
No
other weld process can provide the manual or automated
weld quality
on carbon steels or alloy pipe welds
2009: A
UNIQUE MODIFIED TIG PROCESS CALLED TIP-TIG:
[]
Is your organization interested in a semi-automatic TIG weld process that will
on any application provide welds 2 to 10 times as fast as traditional TIG or SMAW?
[]
Would you be interested in a no bells and whistles, weld process that will consistently
provide defect free welds and weld quality levels never before attained on any alloys?
[] Are you concerned about the new OSHA
requirements for stainless weld fumes and would like a process that does not require
exhaust equipment for most welds?
For more data on TIP TIG Welding call here.
THE
NORTH AMERICAN, PATENTED TIP TIG PROCESS
IS THE WORLD'S MOST EFFECTIVE WELD, CLAD, HARD FACING AND BRAZING PROCESS. TIP
TIG IS PROCESS WHICH WILL DELIVER SUPERIOR WELD QUALITY AND PRODUCTIVITY
THAN TRADITIONAL TIG / PLASMA WELDS. A BONUS FOR ANY WELD SHOP IS WHILE GETTING
THE ULTIMATE IN TIG WELD QUALITY, THE PROCESS IS EASY TO USE ON ANY ALLOY OR ANY
APPLICATION AND IT'S 3 TO 8 TIMES FASTER THAN A TRADITIONAL TIG:
Why be concerned about the skilled TIG or SMAW welder shortage when on the TIP TIG process is
easier to use. TIP TIG weld procedures are are two simple amp / wire feed weld parameters and easy to produce for all manual or automated applications. TIP TIG will dramatically reduce your weld rework
costs and reduce your product liability concerns as this process will always will
deliver the optimum in weld quality. There is no weld smoke issues even with stainless and no concerns
for spatter. The higher TIP TIG weld speeds and focussed
EN arc provide much less weld heat input than regular TIG. If defect free welds with superior weld
appearance are important to you vist the TIP TIG section at this
site.
 TIP TIG HOLDS FREQUENT WORK SHOPS IN PHILADELPHIA.
ED CRAIG
AND TOM O'MALLEY PROVIDE THE WORK SHOP WHICH COMPARES TIP TIG WITH MIG - PULSED MIG
- FLUX CORED AND TRADTIONAL TIG.
THE WORK SHOPS PRESENT THE PROCESS AND DEMONSTRATE
THAT ON STEELS, ALUMINUM, STAINLESS, INCONEL, DUPLEX, TITANIUM OR ON ANY ALLOYS,
THAT THE EASY TO USE TIP TIG WILL PRODUCE SUPERIOR WELD QUALITY THAN THAT ATTAINED
WITH TRADITIONAL TIG AND PRODUCE THAT QUALITY AT MIG OR FLUX CORED WIRE FEED RATES.

WILL THE BEIJING
STADIUM BE A BIRDS
NEST FOR THE SPECTATORS OR END UP
AS A SPIDER'S WEB?
Written
by Ed Craig. Posted www.weldreality.com. Aug. 2. 2008.
The
five hundred million dollars, Beijing Olympic stadium, is wrapped
with a unique high strength steel box cocoon that weighs approx. 45,000 tons.
At the end of July, two weeks before the 91000 seat stadium was ready to host
the 2008 Olympics, I watched a Discovery Channel program about the stadium construction.
The steel bird's nest design is without question, a wonder to behold,
however having a slight interest in fabrication and welding you know where my
focus was, and I did not like what I saw. May
2009 Beijing Update: Check out what's happening to this
architect design wonder,nine months after Ed wrote his opinion on the poor welds
and construction at the Birds Nest stadium.
 April
2009: DEFECTIVE WELDS NOTICE. REFERENCE 2005 AND 2006 SUZUKI SGSX-R1000 MOTORCYCLES:
More data
in bad weld section
of this site.
Note from Ed. I
saw pictures of these critical bike frame welds, they had extensive lack of weld
fusion and porosity. The extent of
the weld defects suggest a complete lack of weld manufacturing process
controls from the Suzuki management.
If I owned one of these Suzuki
bikes, I would not accept the Suzuki management recommendations of a brace, glue,
or even a weld repair. The weld reality is, the lack of weld fusion defects on
these bikes are not repairable as the weld repairs will never provide the weld
integrity desired by those who designed the bikes. Therefore there is only one
logical recourse. I believe anyone owning one of these bikes should be concerned
about what they cannot see and that's the potential lack of weld fusion and it's
impact and the weld repairs impact on the structural integrity of the bike's frame.
If I owned one of these bikes, I would demand a complete refund or replacement
of the bike and also seek legal representation to sue Suzuki for putting my life
at risk.

WHY PURCHASE USELESS, ELECTRONIC BELLS AND WHISTLES
AND OVERPAY FOR YOUR MIG EQUIPMENT?
It
was Ed's job as a training / product manager with Praxair, Airgas, AGA and Liquid
Carbonic, to test MIG equipment and weld consumables from around the globe. You
can pay $2000 for a CV power source, or $12000 for a pulsed MIG power source.
With The MIG process control expertise available in Ed's process control training
resources,
you will attain the same weld quality and productivity results from
both power sources on the majority of steel and stainless applications.
[]
WHY PAY UNNECESSARY HIGH COSTS FOR FLUX CORED AND METAL CORED WIRES, OR
PURCHASE THOSE USELESS, COSTLY THREE COMPONENT GAS MIXES?
Many
shops are using metal cored wires and flux cored wires that can cost from $2/lb
to $4/lb, when the same quality and productivity will be attained from a MIG wire
that costs $1/lb. Global MIG gas confusion has been the norm for more than five
decades. There
are more MIG gas mixes available than cereals in a super market. It's also a sad
fact that the majority of the gas information found in weld
shops, is based on process ignorance and salesmanship, rather than on technical
substance. If you use three part gas mixes for the common  steel
and stainless applications, you typically are part of an industrial gas marketing
/ con game. Ed was on the AWS committee that wrote the USA. MIG gas specifications,
he also developed four of the most practical two part MIG gas mixes sold in North
America. If you want MIG gas mix reality, this is the site.
[]
IF MACHINIST ARE NOT ALLOWED TO PLAY AROUND WITH THEIR EQUIPMENT CONTROLS, WHY
WOULD ANY WELD MANGER OR SUPERVISOR ALLOW THEIR WELD PERSONNEL TO "PLAY AROUND"
WITH THEIR SIMPLE MIG AND FLUX CORED WELD CONTROLS?
Since
the introduction of the MIG process over 50 years ago, there has been little management
or engineering focus on weld process control expertise. The result is the majority
of global weld personnel will this week "play around" with their MIG
or flux cored weld controls. Ed developed the world's most simple, self teaching,
weld process control training method.
With this training tool, in a few hours your employees will have the process control
expertise necessary to instantly set correct, optimum weld parameters for any
MIG / flux cored, steels, alloy steels, stainless, nickel alloys or aluminum applications.
[]
WHY WOULD ANY
MANAGER AND ENGINEER ACCEPT POOR ROBOT MIG WELD QUALITY & UNACCEPTABLE
WELD PRODUCTION EFFICIENCY?
To
attain optimum robot MIG weld quality and productivity or instantly deal with
robot weld issues, requires MIG weld process control expertise. With the global
average robot MIG weld production efficiency range at only 40 to 60% of it's real
potential, and robot weld rework usually in the range of 30 to 100%, many manufacturing
companies have a great opportunity for dramatic robot cost reductions and robot
weld quality improvements.
Ed was the North American Robot Weld Mgr. with
ABB Robotics. Today as a consultant he has provided robot weld optimization to
hundreds of companies using all makes of robots. Why not provide your employees
with Ed's easy to use, Seven Steps to Robot Process Control" training
program, and his MIG and flux cored weld
process control books and CDs.
Imagine the satisfaction attained when after
a few hours of viewing his training CDs, all your weld personnel will have the
ability to instantly address the daily weld issues that impact your robot / manual
weld quality and productivity.
[]
YOU MAY
NOT WANT TO ASK YOUR MANUFACTURING MANAGER, ENGINEER OR OR WELD SUPERVISOR,
THE COST OF THAT COMMON 1/4 (6mm) MIG OR FLUX CORED FILLET WELD.
 Ask
a weld supervisor or fabrication manager the cost of a MIG or flux cored weld
and typically they want to talk about the cost of the gas or the weld wire.
You can weld a vertical up flux cored fillet at 6 lb/hr, or weld the same fillet
at 12 lb/hr. You can MIG weld a horizontal / flat fillet at 6 lb/hr or 20 lb/hr,
yet few managers or supervisors have the process control expertise necessary to
control their welding labor costs.
Ed's low cost, process control training
resources
enable the attainment of consistent, optimum MIG and flux cored weld quality and
productivity and also simplifies weld costs...
[]
WHY
BE CONCERNED ABOUT THE SO CALLED GLOBAL SHORTAGE OF MIG & FLUX CORED WELD
PERSONNEL?
If
you utilize my unique weld process control training methods
that encompass the unique requirements for weld process controls, it takes approx.
30 hours to train a none weld individual to provide MIG and flux cored welds that
will meet any global weld specification, code, or weld qualification requirements.
If your organization has to qualify welders to pass an all position flux
cored pipe or vee groove weld test, you will dramatically improve the pass rate,
if before the welders strike an arc, you provide the weld personnel with a four
hour classroom training program that actually shows them the correct techniques
and settings for flux cored weld process
optimization.
 IN
A RECESSION OR DEPRESSION, YOU CAN LISTEN TO A SALESMAN AND THROW DOLLARS OUT
OF THE WINDOW, OR TAKE THE UNUSUAL STEP OF MANAGEMENT OWNERSHIP OF THE WELD PROCESSES
AND EQUIPMENT THAT'S RESPONSIBLE FOR YOUR PROFITS.
WITH PROCESS OWNERSHIP
AND THE WELD PROCESS EXPERTISE AVAILABLE
AT THIS SITE, YOU WILL HAVE THE TWO ESSENTIAL TOOLS NECESSARY TO INSTANTLY PROVIDE
OPTIMUM WELD QUALITY AND PRODUCTIVITY.
 THE
MISSING LINK FOR MOST GLOBAL WELD COMPANIES THAT UTILIZE MIG AND FLUX CORED IS
"WELD PROCESS EXPERTISE"
API-ASME-AWS-NACE-ABS,
all weld codes require optimum flux cored and MIG weld procedures for qualification,
yet every critical weld that has a defect or has failed, is a weld made with so
called pre-qualified weld procedures. What is an essential element to the success
of any weld project, is the welders response to the numerous variables that daily
influence the welds on the shop floor or at the project.
Apart from
"playing around" with their weld controls, how do your weld personnel
respond to welds that have undersize or excess root gaps, weld joint misalignment,
poor weld edge preparation, poor weld joint access, difficult out of position
welds, unacceptable surface conditions, ever changing environmental issues, distortion,
spatter, undercut, porosity, cracks or lack of fusion?
The welders tools to address variables and weld issues are the weld equipment,
the available weld transfer modes and the consumables utilized. The solutions
to preventing weld issues will be the one thing that weld shop never teach their
employees "weld process control expertise".
All welders should
have the ability to instantly change and provide optimum MIG and flux cored weld
parameters to deal with the common variables and prevent weld defects from occurring.
Welders should be using the correct weld transfer modes, optimum parameters and
the recommended weld techniques for the consumables and application, not their
self taught techniques or the instructions taught by a weld instructor or weld
supervisor more comfortable with the SMAW process.
Every weld shop
will derive tremendous benefits from management, engineers, technicians and employees
who have been trained to be aware of the root cause of MIG and flux cored weld
defects. It has to be beneficial when weld decision makers are aware of the weld
solutions that will prevent those defects from occurring. You can call in another
salesman or take a look at these unique manual / robot MIG. TIG and flux cored
weld process control training resources.

LACK OF GLOBAL BEST WELD PRACTICES.
LACK OF ROBOT WELD PROCESS CONTROLS.
OWNERSHIP,
ACCOUNTABILITY, LIABILITY, CONCERNS.
For
every three robot MIG welds in the auto / truck industry,
you will typically
find at least two welds with lack
of weld fusion.
The
weld reality of the robot MIG welds that join cars and truck parts, is that the
average weld size is 4 mm, while the average gage part thickness is less than
3 mm. Thanks to the general lack of best weld practices and lack of MIG process
control expertise in these industries, it's too frequently the "over
weld" rather than the robot MIG weld integrity that holds together
those $20,000 to $40,000 vehicles.

 2008:
WHERE
ARE THE GLOBAL WELD MANAGERS? Visit
the world's largest career web site "monster.com" and type in the key
words "QUALITY MANAGER"
and monster will provide approx. 700 jobs in the USA. Now try the key words, "WELD
MANAGER" and typically nothing comes up. The reason is simple, the
welding industry is simply not used to weld management. In the majority of global MIG
weld shops, few managers have
established best MIG and flux cored weld practices, few managers have implemented
weld process controls, few managers take ownership or get to
the root causes of their daily welding
issues and even fewer could tell you the cost of a 6 mm, MIG fillet weld, one
meter in length.  ROBOT
WELD COST CONSEQUENCES FROM LACK OF MANAGEMENT PROCESS OWNERSHIP.
For
more than two decades, in global manufacturing facilities, over
90% of MIG welding robots have been set up, and owned by technicians, and the
majority of those technicians were not been provided with MIG weld process control
training. Combine the general lack of
MIG weld process control expertise, with the frequent apathetic engineering /
manufacturing standards that result in the common, unacceptable, weld part dimensional
tolerances. Mix in poor welding fixtures and poor maintenance and you have to
end up with extensive cost consequences. In 2008, as it's been
for the last two decades, you will find the average global, robot MIG / MAG weld
production efficiency range is 40 to 65% and the
average robot weld rework range is 10 to 100%. Aug
2008. ThyssenKrupp Announcement: The NSB
NewSteelBody is a concept for a lightweight steel
auto body developed by ThyssenKrupp Steel. The benchmark for the NSB was the body-in-white
of a real volume-produced vehicle. The NSB body performs just as well as the production
benchmark but is 24 percent lighter and only three
percent more expensive. The reasons for this are the use of high-strength steels,
weight-optimized tailored products and a tube-intensive design which makes full
use of the weight reduction potential of modern steels. Traditional stamped and
welded parts are replaced by tubular components which are stiffer than conventional
parts and better utilize existing space.  2008.
Response to Krupp announcement from Ed: Tubular components
as found in car seats and now car frames are great for increased stiffness, however
tubular components offer unique robot MIG weld fusion concerns. In a "J"
groove joint associated with round to flat gage parts, the required increased
weld mass for the fill, dissipates some of the energy that would typically be
applied to the parts side wall weld fusion. Combine this with the frequent short
cycle weld times and fast freeze low energy welds on thin gage parts and you will
often end up with welds that on the surface look sound, however like this 1.4
mm tube to brkt weld macro reveals, lack of MIG weld fusion will be common. Robot
welding around cold rolled components often coated in lubricating oil from the
manufacturing process also brings up interesting weld challenges, such as controlling
the robot TCP and attaining consistent robot weld speeds from the robot's multi-axis
movement. The quality and consistency of the robot programming and the influence
of tip wear and wire helix issues all impact weld fusion. The weld solutions to
all of these issues are addressed in my robot weld process control training
resources.  Note:
Tubular welds also also concentrate weld heat in a small localized area. On thin
gage HSS steels, that weld heat has to be a concern especially when weld rework
is applied as is typical on too many auto / truck robot applications. To
retain some of the structural integrity in the weld's heat affected zones on these
new high strength steel tubular parts, it's going to be critical
in the robot welding of these high strength components, to ensure that manual
MIG weld rework is minimized and the welds produced provide consistent weld fusion
with minimum weld heat input. This is one application you will not want your millwrights,
electricians or other inexperienced technicians and maintenance personnel playing
around with the robot weld parameters and making changes to these robot welds
during the afternoon shift.
It's fine for designers and engineers to talk about the reduced weight benefits
of high strength steels, however if you destroy the properties of those steels
in the weld locations with questionable welds and weld rework, what's the real
benefit of the high strength tubular steels in a crash? Successfully welding these
future vehicle structures and avoiding future liability consequences, will come
from weld personnel who understand processes and consumables, personnel who will
provide process expertise and apply process
controls. ROBOTS
& MIG WELDING PRODUCTION EFFICIENCY:  In
many plants that use MIG robots, it's typical to find the plants will use three
robots to do the work of two. For more than two decades in the auto / truck industry,
the typical, high volume, robot weld down time per-shift has been 60 to 90 minutes,
which according to Detroit auto industry sources, can result in an approx. cost
of $2000 - $2500 per-hour.  In
mynumerous visits to plants that were having robot
issues, I found that few managers or engineers understood the process root
causes of their daily robot issues and the weld personnel in the plants were not
getting the necessary process control training required to ensure optimum robot
weld quality and productivity. For those engineers and managers interested in
rectifying this situation I would recommend you evaluate the following training
weld process control resources.
 From
a weld process control perspective, are your weld inspectors trained to be weld process reactive
or proactive?
Too
many global manufacturing companies place their labor resources and focus on finding
weld defects, rather than on providing their employees with highly cost effective
the weld process control training programs, that can enable weld defect prevention.
THE
GLOBAL WELD QA DEMISE: There has
never been a bigger demand
for weld inspectors, yet the demand for managers,
engineers,
supervisors and technicians with weld process control
expertise
is almost none existent.

How
many of you have
worked with managers or engineers who have established Best MIG Weld Practices
or Weld Process Controls?
How many weld decision makers have you met that
know their hourly manual weld deposition rates, their robot weld speed potential
for any weld or the real world robot weld efficiency potentials?
How many
highly skilled weld individuals with 20 plus years weld experience, are aware
of the weld process solutions to those common daily robot MIG weld process issues?
How
many weld personnel in your shop could in less than five minutes work out the
cost
of one meter of a common 6 mm MIG fillet weld?
 Note:
Weld procedures are not weld process controls. In north America, we loose billions
of dollars each year to weld rejects and. rework and the majority of those welded
parts had a prequalified weld procedure. Weld process control is the ability to
instantly set parameters that enable optimum weld quality / productivity for any
application and for the variables that will influence that application.
 FOR
DECADES, I WALKED THROUGH GLOBAL WELD SHOPS , SEARCHING TO FIND WELD DECISION
MAKERS WHO WERE NOT INFLUENCED
BY A SALESMAN:
As
a training manger or marketing manager for Praxair, Airgas, AGA, and Liquid Carbonic,
I should know a thing or two about the sales influence on the welding industry.
Thanks
to decades of global MIG weld industry reliance on sales advice, three of the
largest growth and most profitable weld products sold in industrial nations are,
[1] costly pulsed MIG equipment,
[2] metal cored wires,
[3] three
part gas mixes.
If these products were no longer available to weld shops that
weld mostly carbon steels, low alloy steels and stainless, there would be no impact
on the global weld industry's weld quality and productivity.
Weld
Ownership, Responsibility and Accountability should
not start with the local
weld sales rep:
When
MIG or flux cored weld advice is needed, many weld shops with weld personnel who
have been in the business for decades, will not think twice about asking the local
weld equipment rep or salesman who just graduated college with a degree in either
English or Fine Arts. This rep is usually ready to recommend a new, useless three
part gas mix, or the latest $11,999.99 pulsed MIG power source with it's programmable,
magical wave forms, sensitive circuit boards and short life span.
Process
Controls: Welding is a trade
in which during the last fifty years the focus has been mostly on the welder's
skills. Of course the MIG and flux cored processes require skills, however for
process optimization especially with weld automation, process control expertise
is essential. Take a look around your weld shop and watch your highly skilled
weld personnel play around with those MIG controls.
Best Practices: In
most global plants best weld practices has never been implemented. Take a
look around your shop, how many different power sources, welding wires and gas
mixes can you count?
Weld Costs: When asked about
weld costs, the
majority of global weld shops will
want to discuss the cost of the weld wires or weld gas mixes. Deposition rates
are two words rarely used and too many welding supervisors lack the ability to
work out the cost of a common
6 mm fillet weld.
Note:
If it takes you more than 5 minutes to work out the cost of any weld, you lack
weld process expertise.
FOR
MANY MANAGERS , LACK OF PROCESS OWNERSHIP LEADS TO LACK
OF WELD QUALITY AND
PRODUCTIVITY RESPONSIBILITY AND WHEN WELD
ISSUES OCCUR, THE FINGERS TYPICALLY
POINTS TO THE SHOP FLOOR.
 IF
MANAGEMENT, SUPERVISORS, ENGINEERS AND TECHNICIANS WOULD EMBRACE THE LOW COST
PROCESS CONTROL RESOURCES AVAILABLE AT THIS SITE
AND INCREASE THEIR DESIRE FOR WELD PROCESS OWNERSHIP, THEY WILL ATTAIN THE KEYS
THAT OPEN THE DOOR TO WELD PROCESS OPTIMIZATION AND EXTENSIVE WELD COST REDUCTION.

 The
MIG process is over fifty years old, and yet I wonder how many weld decision
makers in a weld shop would be able to answer the following fundamental weld
questions.
 THE
RELEVANCE OF MIG & FLUX CORED WELD PROCESS EXPERTISE?
If
it takes you more than 15 minutes to provide the correct answers to the following
seven fundamental weld questions, you are not in control of the world's most common
weld equipment and consumables.
|
[1]
What is the wire feed setting in inch/min (m/min) in which an 0.045 (1.2mm) wire
with argon - 20% CO2 goes into spray transfer?
[1b] What changes are necessary
if you change the MIG gas to argon 10% CO2?
[2]
Using an 0.035 (1mm) wire, what wire feed setting in inch/min (m/min), does short
circuit transfer change into spatter producing globular transfer, using argon
20% CO2?
[3] You are using a robot to weld a common 3/16 (5mm) carbon steel,
horizontal fillet weld with an 0.045 (1.2 mm) wire and argon - 10%CO2. You need
to attain a weld travel speed of > 45 ipm. Provide the Wire Feed Speed_____Volts___.
[4]
This robot cell goes through six contact tips each day. The robot welds 1/4 (6mm)
carbon steel, using an 0.045 MIG wire and argon 10 CO2. The wire feed data is
280 inch/min (7 m/min) with 25 weld volts. Why the tip issues?
[5] With
a robot, set the flux cored wire feed setting, weld travel rate and voltage to
weld a 1/4 (6mm), horizontal fillet weld with an 0.045 (1.2mm) E71T-1 flux cored
wire and argon 20% CO2?
[6] What is the weld cost for a part which has
80 inches (2 meters) of 1/4 (6 mm) horizontal fillet welds on each part. You are
using an 0.045 (1.2mm) wire that cost $1 /lb. Your argon CO2 mix cost $40 per-cyl.
The wire feed rate is set at 420 inch/min, with 30 volts. Your welders have an
overhead rate of $40 / hr. The welders average arc on time is 30 minutes per-hr.
[7]
You have two welds to make on 1/4 (6 mm) carbon steel. The flux cored wire is
an E71T-1, size 0.045 (1.2mm).
(1) Provide the optimum wire feed and voltage
setting to weld a vertical up 6 mm fillet weld.
(2) Provide the optimum wire
feed and voltage setting to weld a horizontal 6 mm fillet weld.
[8]
You have an automated weld unit that runs on a track. Your spray MIG weld is oversize.
Without touching the wire feed rate, you increase the weld travel rate by 20%.
What will you have to do to the voltage and explain why?
Note: If you have
difficulty with these eight fundamental process questions, don't feel frustrated,
after all, for more than five decades, the weld industry and weld educators have
placed minimal focus on the subject of MIG / FCAW process control expertise.

consistent daily optimum weld quality and productivity will never come without
weld process knowledge. If
you are interested in further testing your level of weld process control expertise,
why not give these two weld process tests a try;
[]
Ed's flux cored process control weld test,
[] Ed's MIG process control MIG Welding test.
After
the weld tests, ask your self, is this type of weld process control knowledge
and data important to the reputation and profitability of your organization?
YOU
MAY KNOW A MANAGER OR ENGINEER LIKE THIS: This
is the manufacturing manager with his head in the sand. This man believes that
MIG welding is a play around with controls trade. He believes that weld productivity
is measured by how long the welder's hood is down and his company's weld quality
will depend on the temperament and artistic skill level of each welder.
 When
you ask this manager about his weld costs, he typically will want to discuss the
cost of the weld wires and gas mixes. When this manager has weld issues, he will
not think twice about calling Lincoln or Miller or asking the local weld sales
rep for advice.
This is the manager who has no problem spending unnecessary
dollars on the latest three part gas mixes or on costly MIG equipment loaded with
ineffective electronic bells and whistles.
This
will be the manager who daily accepts inconsistent, manual, weld quality and unacceptable
productivity as the norm, and his expectations from those costly robots is not
too great.
AND
YOU MAY KNOW MANAGERS / ENGINEERS LIKE THIS:
[]
These are the managers 
and engineers who are tired with futile finger pointing, and fed up with vendor
sales reliance. [] These individuals are frustrated
that their experienced weld personnel have to "play around" with the
fifty year old MIG process. [] These managers no longer want to read weekly
reports full of excuses for their inconsistent, robot / manual, MIG flux cored
weld quality and productivity. [] At weld or engineering meetings these
weld decision makers will want to quickly get to the root causes of their daily
weld issues and know what engineered steps are being implemented to resolve those
issues. [] These are the managers that know that optimum MIG weld process
performance comes with Best Weld Practices and from the implementation of Process
Controls. These managers will
know that to achieve this their employees will need special process control training.
[] These managers will have marked on their
calendars the date that uniform Best MIG and flux cored Weld Practices will
be implemented and will celebrate the day when effective Robot Weld Process
Controls are in place.  Where
there is weld inconsistency and weld process confusion, there is always the opportunity
for dramatic cost savings. You
get to the root cause of the weld issue and the weld resolution and cost reduction
is one step away.
I
hope this site can be a catalyst for progressive, cost effective weld changes
for your weld facility. I hope that the information encourages managers and engineers
towards weld process ownership and reduces some of the common MIG / flux cored
weld process issues, myths, confusion and sales reliance that's common in global
MIG weld shops.

When
management should present
the keys to the weld shop personnel.
Ownership, responsibility and accountability for
high volume, manual or robot, MIG and flux cored weld quality and productivity,
has to start and end in the front office. The
keys for weld process ownership should only be presented to the shop floor
once; [1] Uniform Best Weld Practices are established. [2] All welds
are Pre-qualified and Procedures are provided with narrow operating ranges. [3]
Process Controls are implemented. [4] Manufacturing and Weld Instructions
are complete and highly visible. [5] Training is provided in the assembly,
the equipment, the process and the acceptance criteria. [6]
Dimensional tolerances are maintained to the design. [7] A method for
daily weld evaluation is established. [8]
A Proactive Preventive Maintenance Program is established. These
steps and their requirements for both manual and robot welds, are well covered
in Ed's MIG and flux cored, easy to use, process control training resources: []
NO ONE USES MORE FLUX CORED WIRE THAN A SHIP YARD. [] NO ONE HAS GREATER DEGREE
OF WELD DIFFICULTY THAN A SHIP YARD. [] NO ONE HAS MORE FLUX CORED WELD DEFECTS
THAN A SHIP YARD. [] NO ONE HAS GREATER POTENTIAL TO REDUCE WELD COSTS THAN
A SHIP YARD. [] NO ONE HAS GREATER WELD REPAIR COSTS THAN A SHIP YARD.
YET
MOST GLOBAL SHIP YARDS HAVE NOT ESTABLISHED BEST WELD PRACTICES AND THE MAJORITY
OF YARDS HAVE NOT PROVIDED THEIR EMPLOYEES WITH MIG AND FLUX CORED WELD PROCESS
CONTROL WELDING TRAINING:
 In
the weld cost section, take a look at the multi-million dollar cost savings, one
ship yard attained, using Ed's unique, one day flux cored process control welding training program.
MIG
OR FLUX CORED, THERE IS ONE WAY TO QUICKLY ATTAIN BEST WELD
PRACTICES AND WELD PROCESS CONTROL EXPERTISE.
My
unique MIG and flux cored Best Weld Practices and Process Control training resources
are available in both book and CD form. I have developed these materials over
four decades. With my self teaching CD, Power Point training weld programs,
within an eight hour training period, your MIG and flux cored weld personnel will
be able to;
 [1]
Master the weld equipment and attain it's full performance potential for all carbon
steel, alloy steels and stainless welds.
Attain consistent, optimum weld quality and productivity from low cost MIG equipment.
No more MIG and flux cored weld process issues. No more "playing around"
with the manual or robot weld controls.  [2]
Master the available weld transfer modes. Be aware of the wire feed / voltage
weld optimization requirements for short circuit, spray and pulsed. Imagine
the benefits in a weld shop where all the welders have the same uniform, logical
approach to weld process controls. Imagine a weld shop in which all weld personnel
are aware of the root causes of the manual / robot weld problems and have the
ability to provide instant, logical solutions.  [3]
Understand the weld consumable types / diameters and parameter requirements to
enable optimum weld quality / productivity. Understand the relationship between
the wire diameter, the weld transfer mode, the part thickness, the weld deposition
rates and weld travel speeds. Be aware of the optimum weld gas for that application
and why it's the optimum gas. Control your weld costs through Ed's simple method
for weld cost controls.
 [4]
Forget those stick welding techniques that 50% of the MIG welding industry
uses. Utilize the very specific MIG weld techniques necessary for the weld transfer
mode, consumable, application position and part thickness. Imagine a weld shop
in which all the weld personnel use the correct weld settings and techniques.
It's
always a "rare pleasure" to watch weld personnel act in a professional manner and
instantly set optimum manual or robot weld parameters for their application.
When technicians, managers and engineers, focus on Best Weld Practices and Weld
Process Controls, weld issues are eliminated and weld profits are at their highest.
 Sixty
participants from 6 countries including Australia, England, Spain, Mexico and
Canada, attended Ed's Cleveland Ohio, Robot MIG Weld Process Control work
shop. How
Ed's Robot Process Weld Control training CD
influenced the Ford F-150, the
world's biggest selling truck.  Jan
2007: Ed I wanted to send update about that E-Town plant that you visited a few
years ago: As you know on your first visit to this plant, our robot lines were
producing less than 40, Ford F-150 truck
frames per-hour and the majority required
extensive weld rework. Thanks to your weld process control training approach and
your and consumable recommendations, the results from our employees are today
staggering. Yesterday this plant hit very close to a record of 76
frames per hour. We daily attain our average goal of one frame per-minute.
We had two recent weld audits. One weld audit had a total of two failures, and
the 2nd weld audit was the first 100% pass weld audit in the history of the Ford
F-150 line. A
Grateful Employee
Dana
Corporation.
March
2007: Hey Ed:
Instead
of using the 0.052 wire and Rapid Arc (Lincoln's pulse program). Just thought
I would drop you a line and let you know
that in the beginning of April we will be working on switching over the 5th Dana
plant to your process, parameters and and consumable recommendations. Thanks again
RG.
 Note
from Ed: It's great to hear a robot welding success story like this, especially
as the truck frame weld quality and productivity results were eventually attained
with fundamental weld process and consumable logic. The robot process control
data and advice I provided this company is available in my books and in my Robot
/ Manual Weld Process Control Training CD programs located here.
I
hope you have been to the pulsed section to view if
you need to waste $6000
to $120000 on that new pulsed MIG power source. GLOBAL
MIG WELD GAS CONFUSION:
 There
are more than 60 MIG gas mixes available for your MIG applications.
In
general, the common global MIG gas confusion is simply a
reflection of the
global weld industry lack of MIG process expertise.
Ed
provides the six MIG gas mixes
that provide real world weld benefits.
Note:
Working as marketing and process training manager with AGA,
Airgas and Liquid
Carbonic, Ed developed four of the
top selling MIG gas mixes used in North
America. If
a plant cannot fully control the manufacturing equipment or processes,
is
the issue with; [a]
the equipment or processes?
[b] the people who sold the equipment and processes?
[c]
the shop floor workers?
[d] the plant's managers and engineers?
2008: ENGINEERING AT IT'S BEST, OR IS IT ENGINEERING AT IT'S WORST?
As
the automotive executives line up like sheep to borrow billions from American
taxpayers, any logical individual would ask. Why does the auto industry, which
has one of the highest ratio of engineers to workers, annually create approx.
20 billion dollars in rework, rejects, recalls, warranty and productivity issues?
In
the same industry, hundreds of millions of dollars are lost each year from robot
weld rejects, weld rework and poor robot weld production efficiency, yet the
majority of plants seem to lack the ability to establish uniform best weld practices
and process controls with it's critical manufacturing processes. Perhaps its time
for change.
|
Playing
around with weld controls is the
norm at many manufacturing plants.
If
you are not in complete
control of your weld process,
you
cannot be in control of your weld costs.
2008:
WELD COSTS: If
given the 0.045, (1.2mm) carbon steel MIG wire feed rate, the weld wire cost,
gas and labor costs, how many of the weld decision makers in industrial nations,
would without reference books be able to work out the cost of a common 1/4 (6
mm), manual MIG fillet weld, 1 meter in length.
How
many managers, engineers or supervisors have you met that could look at the wire
feeder and instantly tell you the weld deposition rate of a MIG fillet with an
0.035 (1 mm) wire set at a feed rate of 550 inch/min, or the weld deposition rate
of that 0.045, (1.2mm) E71T-1 flux cored wire, set at 350 inch/min.
The
too common lack of weld process expertise and weld cost control apathy, high lights
why many weld managers and educators have failed for decades to understand the
importance of providing MIG / FCAW weld process control training.
Weld
costs and process controls on any applications are made simple in Ed's books and
CD training resources.
 WELD
JOB DESCRIPTIONS? Weld
quality and productivity issues will always be more numerous in weld shops in
which confused managers, surround themselves with confused supervisors, who are
surrounded by confused engineers, who are surrounded by confused employees who
get no assistance from their confused job descriptions:
This is MIG Weld Reality.
|
The
more than 50 year old, two control, MIG / MAG process is the world's most widely
utilized welding process. I believe if you searched across the industrial nations
that daily use MIG, you would not find more than a handful of mult-plant manufacturing
companies that have implemented Best MIG Weld Practices or MIG Weld Process Controls.
The
four biggest hurdles to implementing Best MIG Weld Practices and Weld Process
Controls;
[1]
Lack of weld management leadership.
[2] Lack of weld
management process ownership.
[3] Lack of process
control training.
[4] Unqualified weld decision makers, imposing
weld equipment, process and consumable preferences based on unqualified weld sales
advice.

ANNUALLY,
THE GLOBAL AUTO / TRUCK INDUSTRY TYPICALLY LOOSES MORE THAN
15 BILLION DOLLARS TO REWORK, REJECTS, RECALLS AND WARRANTY
ISSUES.
IN
THE SAME INDUSTRY, FOR MORE THAN TWO DECADES, MANY MANAGERS HAVE ALLOWED MAINTENANCE
MILLWRIGHTS AND ELECTRICIANS AND OTHER UNQUALIFIED PERSONNEL TO DAILY ADJUST THE
SO CALLED PRE-QUALIFIED WELDING PARAMETERS ON THEIR ROBOT MIG WELDS.
 Joe,
every time I walk past the robot cells, some millwright or electrician from the
maintenance department is playing around with the robot weld data. For
heavens sake our experienced welders play around with MIG controls,
do you seriously believe those guys in the maintenance department
with there 200 amp Miller MIG machine, have the MIG weld process control expertise
necessary to optimize robot MIG welds? Also why are they changing so called, pre-qualified,
weld data without approval and qualification?
ALL
GLOBAL ROBOTS ARE OPERATED, YET FEW ROBOTS ARE MANAGED.
The majority of the technicians and engineers who run your robots are simply
operating a process, rather than in control of that process.

a weld report Ed provided to Ford Frame plant management (Detroit) in the 1980s.

 Oct
2008. In Washington, this man could easily make a statement like this. "You
the voters of the United States asked for government not lobbyist to represent
your needs in Washington and those needs are rarely addressed. At no other time
during the last 100 years of American history has there been such a great need
for change in this self centered, self serving quagmire we call Washington"
If
Obama was an engineer addressing the next AWS welding show he would likely make
a statement like this. "After
more than 50 years of unnecessary, excessive global MIG weld quality and productivity
issues, I hope there are a managers and
engineers that recognize in the weld shops around the globe, it's time for change.
It's time to establish, uniform Best Weld
Practices. It's time for managers and engineers to cut the umbilical cord attached
to their local sale's reps. It's time managers and engineers to stand up and take
ownership of the equipment critical to their organization. It's time those responsible
for welds, understand the real costs of their welds. It's time for workers to
stop playing around with weld controls. It's time to reduce the billions we loose
annually on poor weld productivity, unnecessary weld rework or rejects. It's time
for all weld shops, to grasp the requirements necessary to implement logical,
cost effective, Weld Process Controls".
Thank
god, it's good bye George.
2008:
Thanks George. Eight wasted years, a lost economy,
lost jobs and loss of national
pride and prestige.
