Abstract of the Disclosure The machine disclosed is provided with a mani- pulator which aligns and moves the pipes in course of welding and incorporates a rod for the movement of the manipulator relatively to the welded joints of pipes. The rod is immov- ably attached to a body of the manipulator, is made hollow and is provided with a partition subdividing the bore of rod into two spaces. One of the spaces is intended to be filled with a working fluid and the other accommodates on the partition a hydraulic system for feeding and controlling both the actuators of pipe-holding clamps and a means of moving the pipes in course of welding, the means comprising hydraulic cylinders whose bodies are immovably attached to the body of a movable aligning unit between hydraulic cylinders which are mounted on one unit to actuate the clamps holding fast one of the pipes welded whereas the piston rods of the hydraulic cylinders moving the pipes are immovably attached to the body of the manipulator insulated electrically from an immovable aligning unit.
