Abstract
PURPOSE: To make the height of deposition of weld metal constant by setting the travel speed of a welding torch as desired, operating the mean value of welding current, comparing the same with the current value at the current point and changing the travel speed of the welding torch.
CONSTITUTION: A switch 15 is closed and the variable resistor 36 of the travel motor 6 of a torch 8 is set as desired, thence welding is start. Then, the first circuit operates to operate the mean value of welding current. After the set time, the mean value is stored in the second circuit 29. At this time, the drive circuit 14 of the travel motor 6 changes the rotating speed of the motor in proportion to the output signal voltage of an operational amplifier 37. Therefore, if the welding current at the present moment becomes larger than the previous mean value, the travel speed of a truck 5 becomes faster than the set value of the variable resistor 36 and if it becomes smaller, the speed becomes slower. Namely, if the deposition height increase and the current increases, the truck 5 is run faster, and if they become converse, the truck 5 is run slower, whereby the deposition height is corrected.
