Abstract
The machine uses a welding transformer with current leads on the outside of the pipes and a manipulator inside the pipes. The manipulator uses a stationary and a moving centering block, each with hydraulic clamps for radial clamping of the two pipes, and a tube is employed to move the manipulator w.r.t. the butt joint. The tube is fixed to the manipulator housing and contains a sepg. wall forming two chambers, one filled with hydraulic fluid, the other contg. the hydraulic system operating the radial clamps and moving one pipe during welding by means of a ring hydraulic cylinders.
