ていた。To perform exact size welding using this welding device, the following procedure was performed. That is, after the workpiece 5 to be welded is finished to the exact size, it is fixed by the jig 4 having the exact size shape. Welding is performed by traveling the torch 2 attached to the traveling carriage 3 of the welding machine along the welding locations of two or more objects to be welded 5 fixed by the jig 4.
