Abstract
A tracking monitoring device and a tracking control device are provided for determining the state of how a weld line is tracked under arc sensing control to let the oscillating center of a welding torch track a correct weld line along the groove center based on a welding current waveform when the welding torch is oscillated in the direction of the groove width, and for controlling an arc welding process. The tracking monitoring device and the tracking control device can form a weld line less affected by a short-circuit mode or sputtering mode which serves as a disturbance factor in a welding current value and are capable of coping with a welding speed increase in association with higher speed oscillating frequency.
