Abstract
PURPOSE: To form smooth uranami bead using one welding torch and to improve the ability of joint part, by welding from the first layer to the last layer fixing gas flowing amount at constant, at the time of carrying out butt welding of tube.
CONSTITUTION: The shield gas 11 is blown out from the shield cap 7 and the material to be welded 1 generating arc from the tungsten electrode 5, is rotated in the direction 16 and fusion welding without filler metal is carried out by the soft arc of plasma welding torch. That is, the arc is generated between the electrode 5 and the material 1 when the remote control 12 is made ON and one round welding is carried out accompanied by the rotation of the material 1 fusing the sending core wire 14 and the material 1. Welding on and after the second layer is continuously carried out continuing the above condition. By the above method, control of welding condition is made unnecessary and also, wide and smooth uranami bead is able to obtain.
