ABSTRACT:
Friction welding apparatus for joining a rotatable element to a fixed element by means of a continuous drive system including apparatus for precisely orienting the rotational position of the rotatable element relative to the fixed element. Control apparatus is provided terminating the applied rotational force after a predetermined number of rotations and allowing the rotatable element to enter a coast down welding stage for a predetermined period of time, after which time the coast down rotation is stopped and a final forge pressure is applied whereby the rotational position of the rotatable element is precisely located relative to the fixed element when weldment is complete.
