Welding Laboratory Services

Complete research and development lab for resistance welding applications.

Weld Systems Integrators welding laboratory provides welding, metallurgical testing and validation for a variety of welding processes. Our research and development lab can help improve parts quality, quantify your welding process, create production expectations and evaluate welder performance.

* UPDATE * Weld Systems Integrators announces a significant new addition to our welding lab capabilities. We’ve added a new 12 kilojoule (KJ) Capacitive Discharge (CD) Welder. And we’re currently putting the finishing touches on a a new MFDC “Fast Rise Time” Heavy-Duty Press Welder.
