ABSTRACT:
An apparatus and method capable of applying weld material to metal parts on a generally automatic basis. The apparatus and method are uniquely adapted to apply weld material to the journals and crankpins and crank arms of an automotive type crankshaft on a generally automatic basis. The apparatus comprises a frame and a head stock and tail stock for rotatably supporting a crankshaft relative to the frame. A carriage is shiftable relative to the crankshaft and in a direction generally parallel to the central axis of the crankshaft. A welding torch is carried by the carriage and shiftable longitudinally and generally parallel to the central axis of said crankshaft. A torch positioning mechanism in said carriage includes a member simultaneously moveable in two mutually perpendicular directions by a drive mechanism which also causes rotation of the crankshaft. The movement of the member causes the welding torch to move in a generally true circular path so that the tip of the torch will closely follow to orbiting movement of the crank pins and the journals of the crankshaft.
