FIELD: technological processes.
SUBSTANCE: head contains the welding torch, mounted on the geared plate, mounted on the base with ability to rotate. The head also has its fixing mechanism on the pipe to be welded and the mechanism for adjusting the position of the welding torch, mounted on the geared plate and made in the form of the body, mounted with ability of radial moving with respect to the head axis along the guide, fixed to the geared plate. Two electric motors are installed in the body in mutually perpendicular planes, which is equipped with threaded shafts, one of which is fastened to the stand, fixed on the geared plate, the second one is connected to the rod fastened to the carriage, which is installed with ability to move axially relative to the geared plate axis along the body guide, and the welding torch is fastened to the carriage.
EFFECT: improved method.
