<p>PROBLEM TO BE SOLVED: To provide an equipment and a method for welding by which the distortion due to welding is suppressed and high precision welding is performed. SOLUTION: A plurality of members to be welded 13 is welded to the whole outer peripheral wall of a cylindrical welding base material 10 in the cylindrical axis direction. Following processes are repeated: a disposing process where a prescribed number of members to be welded 13, which is simultaneously welded, is abutted to the outer peripheral wall of the welding base material 10 and disposed thereon in the cylindrical axis direction in such a way that they are radially disposed at equal intervals; a welding process where each abutted portion of the member and the base material is welded by simultaneously applying a welding voltage thereto while pressing the abutted portions; and a turning process where the welded portions are turned around the cylindrical axis by a prescribed angle.</p> |
