ABSTRACT:
The present invention relates to a method of friction or inertia welding first and second metal components wherein one of the components is provided with an interface surface having a generally convex configuration, and the central portion of the convex-shaped surface is provided with an axially extending raised button. The convex-shaped surface and the raised button are simultaneously formed during a forging operation. The raised button ensures that, during the friction welding operation, the initial contact and friction heat build up will occur at the center of the interface surfaces.
