摘要：

PROBLEM TO BE SOLVED: To provide a welding head in which the torch part can be

easily moved in the circumferential direction of the outer circumferential part and in the

vertical movement direction of the tube to be welded even in a narrow gap.

SOLUTION: The welding head is equipped with a ring 1 for torch rotation provided

with a torch stand 10 for supporting a torch 7 at the tip part and rotating around the

circumference of the tube 22 to be welded in such a manner that its central axis is made

coincident with the central axis of the tube 22, a ring 2 for vertically moving the torch

arranged on a concentric circle with the ring 1 inside the ring 1, the first gear group of

rotatively driving the ring 1 around the tube 22, the second gear group arranged in

parallel with the first gear group and rotatively driving the ring 2 around the tube 22, a

driving shaft 27 of jointly driving the two sets of gear groups, a motor 4 for torch

rotation of driving the driving shaft 27, the second gear group, amotor 5 capable of

driving the ring 2 while rotating in the same direction to the ring 1 or the direction

reverse thereto at a speed equal to that of the first gear group or at a speed higher or

lower than that of the first gear group for rotatively driving the ring 2 around the tube 22

and also vertically moving the torch 7.
