Abstract

PURPOSE: To improve accuracy of position control of a torch by finding deviation between current of two welding torches gap of which is made adjustable and a reference signal of horizontal and vertical direction, and controlling the position of welding torch to eliminate deviation in horizontal or vertical direction.
CONSTITUTION: Current is supplied from an electric power source to welding wires 15, 16 of welding torches 10, 11 the gap between them is made adjustable. At this time, if there is no change in the height of welded materials 35, 36 of a base metal 18 and welding torches 10, 11, current IR, IL that flows in the wires 15, 16 becomes constant. Next, if divergence in horizontal direction takes place, current in the welding wires 15, 16 changes and deviation from the value corresponding to initially set arc current occurs. The position of torches 10, 11 is controlled automatically in horizontal direction to eliminate the deviation. When the torches 10, 11 deviate in vertical direction against the base metal 18, the sum of current in welding wires 15, 16 changes to cause deviation from the initially set value. The position of the torches 10, 11 is automatically controlled in vertical direction to eliminate the deviation.
