PURPOSE:To follow up welding without inconvenience and misjudgement in weaving arc welding of a consumable electrode by adding the correcting rate for the center of oscillation in the transverse direction by a prescribed number of oscillation, comparing the same with a prescribed deciding level, correcting the position and correcting also the advancing direction of the torch axis. CONSTITUTION:The oscillating center position in the groove width direction of a consumable electrode is calculated and the deviation from said center is integrated by a prescribed number of oscillation. When the integrated value exceeds a prescribed deciding level, the oscillating center position is corrected. The advancing direction of the torch axis calculated by the integration is corrected in a normal direction. Mis-judgement and inconvenience arise frequently owing to a defective work, defective positioning, defective follow-up operation, etc. with the conventional method for correcting the positional deviation right after the decision but such errors are considerably decreased in this method and since the advancing direction of the torch axis is correctly corrected, the torches follows surely and satisfactorily the groove. |
