Resistance welding differs from fusion welding in that pressure is applied to the weld until the molten area coalesces, cools, and solidifies. Two resistance welding processes commonly integrated with roll forming are high-frequency welding and rotary spot welding. High-frequency Welding From...

Surveying suitability of welding processes for roll formed parts

December 12, 2006

By:

Of the many weld processes used, resistance, high frequency and fusion welding are the most likely to be integrated with roll forming. Welding processes that are integrated with roll forming include GTAW, fusion, plasma arc welding, laser welding, resistance welding, and high-frequency welding. The fusion weld processes most successfully integrated with rollforming are those that are fast and don't require a filler metal.
