Rotary friction welding - Wikipedia
Rotary friction welding (RFW) one of the methods of friction welding, the classic way of which uses the work of friction to create a not separable weld. Typically one welded element is rotated relative to the other and to the forge (pressed down by axial force).
Resistance Welding - types, parameters, & common issues
Seam welding is a resistance welding process for joining metal sheets in continuous, often leak tight, seam joints by directly applying opposing forces with electrodes consisting of rotary wheels. The peripheral shapes of the electrode wheels concentrate the current and the heat generation.
