ABSTRACT:
An automatic weld line following method for use with an arc welding method of welding a work by feeding a consumable electrode toward the weld line of the work through the tip of a welding torch and by oscillating the welding torch. The average and effective values of a welding current are detected, even if they are different, and fed to a computer so that the distance between the tip and the work is automatically controlled. At the same time, the oscillation angle is controlled to be symmetric at all times with respect to the weld line.
