Patent number: 8378251Abstract: A two-electrode arc welding device and two-electrode arc welding method are provided for performing welding with improved penetration performance using two non-consumable electrodes. In a two-electrode arc welding device, a power-supply unit outputs a straight-polarity voltage and a reverse-polarity voltage, which has a different electrical potential than the straight-polarity voltage. The straight-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. The reverse-polarity voltage output from the power-supply unit is applied to a non-consumable electrode of a straight-polarity arc torch, whereby an arc is formed. An arc spacing distance, which is a distance between the ends of both the straight-polarity arc torch and the reverse-polarity arc torch, is set to be at least a minimum distance at which an arc will not occur therebetween (arc spacing critical distance).Type: GrantFiled: January 3, 2011Date of Patent: February 19, 2013Assignee: Honda Motor Co., Ltd.Inventors: Hiroki Fujiuchi, Toshiyuki Horimukai, Tetsuya Kodama
