Generally, when welding workpieces with V-shaped or Since the welding does not spread over the entire width of the groove, the target position of the torch is shifted slightly to the left and right, and welding is performed by distributed welding. However, when distributed welding is performed using a plurality of welding torches arranged substantially in a straight line in the welding direction, a step is formed on the surface of the weld bead, which poses a problem in terms of appearance.
そこで従来は、この溶接ビード表面の段差をな

に設定する必要があつた。 Conventionally, in order to eliminate this level difference on the surface of the weld bead, two torches 13 and 13' were attached as shown in Figures 1 and 2 (side view in the direction of arrow C in Figure 1). The chips 14 and 14' were arranged so that they did not touch, and the arc points were brought close together to perform welding as one molten pool.However, in order to prevent each torch from touching, the extension l was made longer than necessary. Or, it was necessary to set the torch angle in opposite directions.
