摘要
The fusion pipe joint of the present invention is formed without a heat fusion bead on the interior surfaces of the pipe joint. To form the joint, the end surfaces (64) of the two pipe ends (20) are faced by removing a quantity of pipe material from the inner edge of the pipe end surface (90). When the two pipe ends (20) are subsequently heated and brought together, a gap or channel is created, rather than protruding into the interior surface of the pipe joint.
