Abstract
PURPOSE: To prevent deposited metal from hanging down in performing butt welding of circumferential part in all positions by an arc welding machine using a nonconsumable electrode by applying current to a coil wound on the weld zone while the welding electrode moves in a down moving welding area.
CONSTITUTION: A butt weld zone 18 of metallic tubes 10a, 10b is welded in all positions by an arc 24 using a nonconsumable electrode 20. A coil 28 is wound around the tube 10a to be welded and while energizing the coil, welding is performed moving an electrode 20 from 0hr position P0 to 6hr position P6 in a down- moving welding area ED. The welding arc 24 is subjected to force in accordance with Fleming's left-hand rule by the action of magnetic line of force Φ generated in the direction of tube axis by current I that flows in the coil 28, and welding current (i). Thus, the arc is deflected upward opposite to the direction of advance of the electrode 20 and consequently, hanging down of deposited metal in the down moving area ED is prevented.
