"Conclusion: Our capability of the tested material
far exceeds the required 99.5% level and using S.P.C. to
control it through the Weld Computer (SIC) will assure
consistent high quality welds. This method of Taguchi
augmented S.P.C. perfected the process where control
limits can be developed for each weld schedule.
Approvals would mean that the concepts (SIC) is approved
where details of control limits of all alloys will be
developed per the weld schedule."

WeldComputer® Adaptive Control as a replacement for
periodic destructive testing under MIL-W-6858D

"As a tier one
supplier of automotive components, quality is the key to our
continuing success. WeldComputer Corporation's Multi-Channel
WeldView® Monitor has helped us optimize our weld schedules and
maintain control over the consistency of our resistance welding
processes. We have been able to reduce our reliance on
destructive testing while improving our level of confidence in
the reliability of our products."

Robertson, Autotube Limited, Strathroy, ON, Canada

"We have been able to
identify the key characteristics in our material to make
it weld consistently. The WeldView(R) Monitor has been
invaluable in sorting out the failure modes and
understanding how to adjust the weld schedule."

"I evaluated
several commercially available controls in production
environments. I chose the WeldComputer system after evaluation
at the McDonnell Douglas facility, where it was used in the
fabrication of fighter planes. The WeldComputer is
available as a complete control system or a process monitor only
- the WeldView. For Lee Rowan I chose the process monitor to
preserve the company's investment in standard welding controls.
To get the most information with the minimum investment in
sensors, we chose to monitor current and displacement."

"The purpose of
this report is to establish that the resistance welding process
as controlled and monitored by WeldComputer’s equipment, is
sufficiently reliable to allow the substitution of
nondestructive evaluation for the currently required destructive
testing... Because each individual weld’s expansion value
is monitored by the controller, there would be greater
confidence in spot weld quality than with the periodic
destructive monitoring required by Mil-W-6858."

destructive testing
