Abstract: A burring apparatus for a friction welding machine comprises a clamp unit provided at the front end of a horizontal main spindle, for holding work piece W1 coaxial with the main spindle, a clamp unit provided at the front end of a slide movable to and away from the main spindle in the direction of the axis of the main spindle and a doughnut-shaped cutter for shearing off a burr. Work piece W2 is moved forward together with the slide until work piece W2 comes into contact with work piece W1 so that the mated ends of work pieces W1 and W2 are friction welded together to form a joint work piece W. The burr formed on the jointed work piece W is sheared off by the cutter. The jointed work piece W is then liberated from the main spindle.

Abstract: A clamping module for a pipe line-up system uses bell crank linkages to transmit pipe alignment and clamping forces between radially moving clamping feet and a central axially moving driving head. The clamping feet are arranged in axially spaced sets to internally engage two pipe sections to be welded independently on either side of a weld zone between the pipe sections, with welding shoes in between the clamping feet and spanning the weld zone. The bell crank linkages provide a force multiplier between the driving heads and the clamping feet.
