Abstract

PURPOSE: To make it possible to obtain a perfectly-welded part which has no difference in bead height invariably, by automatically adjusting the projection length or swing angle of a welded wire in accordance with open width and also by making automatic adjustments of a wire feed speed or welding speed.
CONSTITUTION: Welding car truck 51 runs along edge 2. From the bottom of switch mechanism box 58, welding torch 12 extends downward and from welding torch 12, welding wire 8 deformed plastically in an arc shape projects. A groove-face sensor not shown in the figure is fixed to welding car truck 51 leading welding torch 12. In this constitution, when an increase in groove-face width is detected in welding, welding mechanism box 58, namely, welding torch 12 is increased in swing amplitude or swing angle to increase the switch amplitude, thereby preventing the defect due to a welding failure. On the other hand, the speed of the car truck is reduced to increase weld deposition or the speed of a motor is increased to prevent a difference in bead height from appearing.
