摘要: A method for joining a first tubular member to second member. The provides stretchable and compressible welding ring having flexible inner ring, resistance coil wound around the at least one layer of plastic coating coil. includes step arranging members in overlapping relation with an end inserted into encircling compressed between members. also applying electric energy melt so that, upon cooling, respective ends are welded ring.
