ABSTRACT:
Disclosed is a method, apparatus, and design of a fusion welded pipe wherein the effects of an inner bead of the fusion weld are minimized. The internal shape of the pipe prior to welding may be configured in several different shapes so that the beads or lips produced by the fusion welding process are unobtrusive and do not interfere with the function of the pipe. In a likewise manner, the outer shape of the pipe prior to welding may be configured so that the lips are unobtrusive on the external surface of the pipe.
