Resistance Seam Welding
Resistance Seam Welding is a variation of resistance spot welding.
In resistance seam welding, the welding electrodes are motor driven wheels rather than stationary rods. The result is a 'rolling' resistance weld or non-hermetic seam weld used to join two sheets together.
For more information about the resistance welding process read our Fundamentals of Resistance Welding.
