Abstract

PURPOSE: To obtain a nonconsumable electrode that provides high-speed welding without flowing molten metal to the rear by forming the front half circumferential part and rear half circumferential part for the advance direction of the welding in prescribed shapes respectively.
CONSTITUTION: Electrode 4 is a columnar electrode of diameter D that has the tip part cut along a couple of plane bevels 14, 14 of angle α in a sectionally V shape with a plane of width (a) left in the center and also cut along semiconic surface 15 with a vertex positioned at position 12 having length (b) away from one end 13 in the radius direction so that the angle of the opposite side to one end 13 of the electrode is β. Therefore, this electrode 4 is cut at three circumferential sides along opposing plane bevels 14, 14 of angles α and conic surface 15 of slanting angle β and has rectangular top part 11 of width (a) and length (b) in a modified wedge shape shifted to one side in terms of the center of the axis. Consequently, using this electrode 4 the arc deflects to the front in the welding advance direction because of the unevenness of a magnetic field generated at the circumference of the tip of the electrode, preventing molten metal from flowing to the rear.
