ABSTRACT:
A welding machine for welding the longitudinal seams in wheel rim blanks which have been rolled into cylinders with the longitudinal edges of each blank forming a longitudinal gap includes a pair of clamping assemblies each having an inside member and an outside member for engaging the inner and outer surfaces, respectively, of the rim blank adjacent the longitudinal edges thereof on opposite sides of the longitudinal gap so as to align the longitudinal edges with each other. At least one of the clamping assemblies is movable relative to the other clamping assembly in a direction transverse to the longitudinal gap so as to permit the longitudinal edges of the rim blank to be pressed against each other. The longitudinal edges of the blank are pressed together in the transverse direction to close the gap and hold the longitudinal edges together during the welding thereof. An electric welding current is passed transversely through the longitudinal edges of the blank while continuously pressing the edges together and while continuously clamping the rim blank on both sides of the gap to maintain the edges in alignment with each other. The electric welding current is supplied to the rim blank through the outside clamping members so that the welding current flows perpendicularly through the weld line. Both the inner and outer clamping members of at least one of the clamping assemblies are supported on bearings to permit sliding movement of these clamping members.
