Abstract

Pipes of large dia. for pipelines are butt welded together by rotating a V-shaped ring which fits in the V-gap of the chamfered pipe ends. When the frictional heat has softened the metal near the ends, an axial force is exerted to weld the pipe ends together and the press the ring outwards. The heavy pipes need not be revolved, only the small ring which can be stopped quickly when desired. This method produces much less internal flash on the pipes than if the pipes are rotated.
