ABSTRACT:
A friction welding apparatus and a method for its use is disclosed where the apparatus includes a plurality of interchangeable components including a drive means, an actuator assembly, a support system and a control system, the combination operable to friction weld a workpiece to a valve body. The apparatus features a means to maintain a positive fluid pressure within the weld chamber during burn-off and upset phases. Such a means is provided to keep out explosive gases emitted by one of the members being welded.
