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.
