Recently, WeldComputer worked with a $20B+ American multinational power management and manufacturing company that produces mechanical supports, cable tray systems, strut systems and accessories, and more. They had started noticing increasing levels of variability and inconsistency with their welds. We were able to: Solve poor fit-up issues Eliminate destructive testing Automatically adjust corrective heat Alert […]
For resistance spot welding, resistance projection welding, and resistance seam welding, the RMS current needed to weld a specific material of a specific thickness will be similar for MFDC as for AC. If all things are considered equal, where the only variable is the weld transformer type, the same KVA MFDC or AC transformer is […]
Manufacturers using inverter technology in seam welding have reported decreased production throughput, reduced weld quality, and increased maintenance.

Benefits include regulating weld consistency, operating at fast production speeds, and improving weld qualityBy Robert K. Cohen Making a gas-tight seal with a seam welding machine involves making a series of overlapping spots. Each spot produced should be a fully formed nugget that is free of expulsion. Using too little heat produces an undersized spot, which can cause a leak. Using too much heat […]
