IPC: B23K37/00
Filed: 1993-03-31
Abstract: PURPOSE:To work without replacing a mandrel when working a work with a different inner diameter in a device welding by putting a cylindrical work on the mandrel. CONSTITUTION:A mandrel is a rod-shaped body with a diameter A, its upper surface is an electrode part 3, and a torch 13 is opposed to it. A work with an inner diameter close to A, is welded by putting it on the mandrel.
