A welding jig having a clamp member for clamping a welding point of an object to be welded, comprising: a clamp board having a supporting portion for supporting the welding point from below; and a pressing portion for pressing the welding point from above. And a plurality of clamp members disposed on the clamp substrate along the direction of progress of welding, and each of the clamp members is connected to each of the clamp members to rotate each of the clamp members independently . It has a clamp driving device, a detector for detecting the position of the welding nozzle, and a control device for controlling the operation of the clamp driving device, and the control device is sent from the detector for detecting the position of the welding nozzle.
It is arranged rotatably according to the welding position detection signal that comes in
A welding jig that outputs a rotation command to the clamp member .
