PURPOSE:To improve the detection accuracy of a weld line by providing a means for setting a position relation of a tip reference point of a welding torch, and a weld line position detecting reference point, and also, moving and setting the weld line position detecting reference point of the sensor. CONSTITUTION:A welding robot is constituted of a robot control box 11, a mechanism part 12, an operating part 13, and a sensor 8. A tip reference point T is set to the vicinity of a weld line position R1 of a work 5 by operating manually the second switch part 13b of the operating part 13. Subsequently, a command is given to a control box 11 by operating the first switch part 13a, the position R1 is derived a through a torch-to-sensor position relation which has been inputted in advance, and also, an operation for shifting a torch position from R1 to R2, and the torch position and the sensor position are shifted to R2 and R1, respectively. Since the position of a torch 2 and the sensor 8 can be set exactly, the detection accuracy of a weld line 5 can be raised. |
