Abstract
A welding head which can easily move the torch portion of the welding head in the circumferential direction and the vertical moving direction of the outer circumference of the to-be-welded tubes even in a narrow gap, includes a torch rotating ring that rotates on the outer circumferences of the tubes by matching with the central axis of the to-be-welded tubes and a torch vertical moving ring disposed concentrically with the ring inside the ring, provided with a torch base for supporting a torch on the front ends, a first gear group for driving and rotating the ring around the tubes, a second gear group that is disposed in parallel to the first gear group and drives and rotates the ring around the tubes, a drive shaft for driving the two gear groups, and a torch rotating motor for driving the drive shaft, and a third gear group that can drive the ring while rotating it in the same direction as or in reverse to that of the ring at a speed equal to or higher or lower than that of the first gear group for rotating the ring around the tubes and vertically moving the torch, and a torch vertical moving motor for driving this third gear group.
