ABSTRACT:
There is disclosed a machine for successively applying weld metal to the journals and crankpins of an automotive crankshaft, by rotating the crankshaft on its axis, and employing a means for causing a weld metal feeding torch to follow the crankpin around its circular or planetary path travel, depositing a bead of weld metal on the crankpin. The torch is also translated along the crankpin, and a bead or beads of molten metal is or are then wrapped around the crankpin, preferably in a succession of adjacent circles, and welds thereto. The layer of weld metal thus added is subsequently machined to its proper dimensions.
