Abstract

PURPOSE: To lessen manpower for welding work and improve the quality of product by controlling the vertical positions of a welding torch detected with the change in welding voltage or current in such a way as to coinside with preset correct voltage or current in copying with the welding head.
CONSTITUTION: Oscillation width l1 slightly larger than the root gap of a groove 2 is set in an oscillation setter 10 setting the lateral moving periods and oscillation width of a welding torch 3, and the period T is set at T=Tr. The position X of this torch 3 has its origin 0 in the central part of the groove 2, and the oscillation width is -l1/2W+l1/2. In the oscillation of the actual torch T, the torch 2 in the horizontal part in the bottom of the groove 2 is kept at constant height and welding is carried out. The controlling in the vertical directions is accomplished by discriminating 15 the difference between the voltage set in correspondence to the correct torch height beforehand in a voltage setter 16 and the value measuring 9 the actual welding voltage and inputting the results of the discrimination to a vertically driving motor 7, so as to make the voltage differenece zero. As a result, the welding is continued by osicllating the torch 3 while maintaining the same at the correct height.
