ABSTRACT:
A line-up clamp (10) is disclosed for clamping small diameter pipe sections together for welding. The line-up clamp includes back-up shoe assemblies (106) which are pivoted into engagement with the interior surfaces of the pipe sections adjacent the weld as the clamp clamps the pipe sections. As the hydraulic cylinder (14) compresses the resilient disks, expanding the disks into clamping contact with the pipe sections, actuator bodies (58, 88) are urged together, with tapered surfaces on facing back-up shoe assemblies moving into contact and driving the back-up shoe assemblies into contact with the interior surfaces of the pipe sections at the point of welding.
