Possible causes and corrective actions for many monitor problems.
In single-phase welding applications where the primary current requirement presents an excessive load on the incoming power lines, WeldComputer wave synthesis control technology offers a practical way to reduce the current demand on each power line by distributing the load over all three power line phases.
If you are in the market for a new resistance welding machine, this article might save you tens of thousands of dollars. Our team collaborates with resistance welding manufacturers to help solve problems of reliability and inconsistent weld performance. This paper describes how you can determine if your existing machine can achieve similar results at […]
Monitoring the resistance welding process can detect anomalies and prevent many problem welds from passing through undetected. Achieving reliable results generally requires profiling the entire response pattern of multiple electrical and mechanical variables. The established setdown upper and lower acceptance limit profile curves allow anomalistic resistance welds from the lead acid battery production operation to […]
Challenges in resistance welding can have potentially dire consequences if not fully and accurately addressed. This paper focuses specifically on addressing one of the key challenges of resistance welding — workpiece variation. That is, the interface between workpieces and the electrode-to-workpiece interactions for heat generation that serve as the basis of resistance welding. We describe […]
The benefits of using adaptive controls in seam welding include regulating weld consistency, operating at fast production speeds, and improving weld quality. This Welding Journal feature article written by Robert Cohen explains the details.
Which is better for performing precision welding, a low-friction pneumatic cylinder or a servo motor? Under the dynamic conditions that occur during weld formation, a good quality welder with a low friction pneumatic cylinder reacts faster, with greater stability and repeatability than most of the servo motors presently in widespread use on resistance welders. The […]
