The machine disclosed is provided with a manipulator which aligns and moves pipes in course of welding and incorporates a hollow rod for the movement of the manipulator relatively to the pipe joints. The rod is immovably attached to the body of the manipulator and is provided with a partition subdividing the rod bore 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 actuators of pipeholding clamps and a means for moving the pipes in the 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 the unit to actuate the clamps holding fast one of the pipes being welded whereas piston rods of the hydraulic cylinders that move the pipes are immovably attached to the body of the manipulator insulated electrically from an immovable aligning unit. It is expedient to use the machine disclosed for welding bigbore pipes into a continuous pipeline. The layout of said machine provides for quick withdrawal and replacement of hydraulic actuating cylinders without taking apart the welding manipulator. This feature adds to the number of purposes the machine can serve, promotes its serviceability and repairability.
