Abstract

PURPOSE: To give the sufficient strength to the forge welded portion and to improve the yield without necessity of cutting off the whole of the metal flow portion, by first finishing both of edge faces of the hoop, which is the raw material of the steel pipe, into a smooth plane of a specified roughness, and then, by performing the forge welding.
