Abstract: PROBLEM TO BE SOLVED: To enable vertical upward welding of a narrow groove in a thick planar structure by synchronizing the movement of the wire with that of the welding torch. SOLUTION: With a welding torch 6 on the left side in a narrow groove 10, if a roller 4 is on the left of the wire feeding unit 1, the wire 8 is supplied to the torch 6 along the outer diameter of the roller 3; therefore, a propensity for bending to the left is imparted to the wire 8, which comes out from the torch 6 while facing to the left. Consequently, the tip end of the wire 8 can be aimed at the corner 17 on the left face of the narrow groove 10, enabling the welding of the left face of the groove 10 without tilting the torch 6. With the torch 6 on the right side in the groove 10, if the roller 4 is on the right of the feeding unit 1, the right face of the groove 10 can be welded in the same action as written above.  Incidentally, the wire feeding unit 1 is moved horizontally by an oscillating mechanism 11, with the center part of the groove welded during this horizontal movement.
