Oil pump gear three-piece inertia welded assembly (Model 180B)

This oil pump gear, formerly a machine forging, was inertia welded faster and more economically from three pieces of bar stock. The task is completed on this Model 180B inertia welder with rather innovative tooling. The operator manually loads three pieces in the machine: one journal in the spindle, and the other journal and gear blank in the tail stock. After cycle initiation, the machine automatically makes the first weld, unclamps the tail stock, and indexes the second journal into welding position. Each cycle produces one piece part consisting of two welds, saving valuable handling time. A simple automatic unloading device further saves operator time.
