Abstract

PURPOSE: To enable to obtain proper bead shape having no concaveness etc. even at high welding speed, by welding both sides position putting between welding place by the other two electrodes after welding by one electrode at the time of carrying out circular arc welding by three electrodes.
CONSTITUTION: At the time of welding the joint of the spiral steel tube 1 etc. by three electrodes 10a, 10b and 10c, both sides putting between welded part by the electrode 10b, 10c, after welding by the electrode 10a arranging the above three electrode in downward slope of the rotating tube 1 and also, arranging the electrode 10a on the weld line 12 and then, arranging the other two electrodes 10b, 10c on both sides position putting between the line 12. By the above method, molten temperature of bead of whole width against width direction is made equal and concaveness of the bead is not produced. Also, proper bead formation is obtained even when welding is carried out at high speed.
