TURNING WELDING METHOD OF ROBOT USING DETECTION OF TERMINATING END

摘要

PURPOSE: A turning welding method of a robot is provided to enhance welding efficiency by detecting a terminating end of a welded member automatically using an automatic detection method on a basis of a voltage signal. CONSTITUTION: In welding a reinforcement using a welding robot, first, a position of a starting end of a welding task to the reinforcement is obtained by usual touch-sensing method. Then, a position of a terminating end(14) of the welding task is detected using an automatic detection function on a basis of a voltage signal of a welding arc which is generated during continuous welding process. If the position of the terminating end(14) is detected, a welding torch of the welding robot is turned at the terminating end(14). Then, a new welding task to the reinforcement is carried out.
