Abstract

An internal spacer clamp for use in welding one end of a pipe to an end of a second pipe. This includes a first spider ring (26) having a first set of pipe contacting pistons for engaging the interior of the first pipe and supported from a frame. A second spider ring (28) having a second set of pipe contacting pistons for engaging the interior of pipe. There is a first power piston (135) for driving each of the pistons in said first spider ring (26) in or out of its hole and a second power piston (38) for driving each said piston in the second spider ring (28) in and out. An air powered pipe spacing power piston (68) supported adjacent said second power piston (38) for moving the second spider ring (28) toward or away from the first spider ring (26). The housing of the spacing power piston is rigidly connected to the housing of the second power piston which is rigidly connected to a cup-like cover which connects the housing of the second power piston to the second spider ring whereby movement in or out of the spacing housing moves the second spider ring either toward or away from the first spider ring. Control air valves control the sequence of pressurized air being supplied to drive the pistons of the power pistons in or out in a selected order.
