CORRECTING METHOD OF WELD LINE POSITION

摘要

PURPOSE:To weld properly for each process by judging the necessity of correcting the weld line position in accordance with the welding conditions of each process in multiple welding processes. CONSTITUTION:If a base mateial is displaced from a reference position, the displaced position is detected and stored by a position detector memory 4 and the position is compared with the reference positioi stored in the reference position memory 6 and the input is made to a displacement memory 8. A position correction judging device 12 receives the input of the displacement amount and the input from the correction position setting device 11 which stores the preclassified and preset welding processes for which the displacement correction is made in synchronism with the input and processes for which no correction is made, and discriminates the necessity of correction for each process. A weld line position memory 9 adds the correction necessity or non-necessity signal for each welding process and indicates each weld line position to a torch position control device 10 to operate the welding torch.
