Abstract

PURPOSE: To improve accuracy of copying control by detecting welding current making the direction of torch always at right angles to the welding face and composing the deviation from bending data of the weld line, and making position control of the torch to eliminate the deviation in the direction of traveling, horizontal or vertical direction.
CONSTITUTION: An estimated weld line of a weldment is stored beforehand as tracking data and a torch direction rotating mechanism 11 is rotated according to the data to move in traveling direction of the torch X, horizontal direction Y and vertical direction Z. When deviation is detected by current detection, the correction signal corresponding to the angle of direction of the torch is distributed to X-axis and Y-axis. Then a composition of the signal in the direction to eliminate the deviation, tracking data and a control signal are inputted to a servomotor of a torch shifting mechanism 3 and to a servomotor of a horizontal shifting mechanism 1. In the direction of Z-axis too, tracking data and a signal of the direction to eliminate the deviation in vertical direction are composed to make a control signal, and this is inputted to a servo motor of a vertical shifting mechanism.
