Abstract

Pipe clamp has two housing sections located inside the pipes adjacent the joint to be welded. A number of clamping chambers are slidably mounted in each housing section for radial movement between extended and retracted positions. A pneumatic drive mechanism is connected between the clamping members in the first housing section and the second housing section for relatively moving the housings and hence the pipe sections to space the pipe sections by a predetermined amount. A weld joint back up shoe assembly slidably mounted on the second housing section moves radially between extended and retracted positions to provide back-up support for molten weld metal during the welding operation.
