Abstract:
A method for forming welded assembly. The method includes: providing a gear workpiece; forming a joining section on the gear workpiece that defines a weld interface; applying a material to the outside surface of the gear workpiece including the joining section; cutting a plurality of teeth in the material-covered gear workpiece, each of the plurality of teeth having first and second flanks and a root, wherein the material does not reside on any one of the first flanks, the second flanks and the roots; heat treating the gear workpiece to harden the teeth; and finishing the heat-treated gear workpiece in a finishing process to form a finished ring gear, the finishing process comprising at least one of a turning operation and a lapping operation; wherein the material is disposed over the weld interface on the finished ring gear. A welded assembly is also provided.
