Abstract

PURPOSE:To perform titled manufacturing without generating pin holes by cutting the outer surface of butted parts facing to the electrode after making a tube by forming a metallic hoop and before welding the butted parts and thereby stabilizing the arc. CONSTITUTION:A metallic hoop 1 is degreased and both side edges in the direction of width are cut to form new end faces 1A. A tube is made by forming to butt the tow end faces 1A. The hoop 1 thus made to a tube is sent in the direction of arrow, and guided by rollers 8 to close the butted part 2. Before welding the butted part 2 by an arc 4 that comes out from the electrode of a welding torch 3, outer surface of the butted part 2 that faces to the electrode 4 is cut by a cutting machine 9 to remove burrs and oxide films and to obtain unoxidized smooth surface. When welding is made under this condition, the arc 5 is stabilized continuously, and a small sized metallic tube 6 that has no pinhole in the weld zone can be manufactured continuously.
