摘要： PROBLEM TO BE SOLVED: To facilitate visual positioning of a weld zone and to enhance accuracy in positioning by penetrating a welding torch through the notch of an arm supporting the torch and by welding the tube and the end of the tube plate from inside to outside. SOLUTION: A supporting rod 4a is provided at the tip end of the supporting arm that performs positioning of a welding head. The supporting rod 4a, reinforcing plate 10 and a lock nut 11 are inserted into the tube hole 121. A forward positioning tool supported by the welding head body 1 is abutted on the tube plate 12 to perform positioning. The vertical adjustment knob 3a of the torch positioning adjuster 3 is rotated, positioning the welding torch 6 vertically so that it fits the outer diameter of a tube 13 to be welded, and adjusting the position in the turning radius direction of the welding torch 6. In addition, the forward/backward adjusting knob 3b is rotated so that a tungsten electrode 8 is directed to the corner of the groove of the tube 13, and the entire torch supporting base 5 is adjusted for positioning in the forward/backward direction.
