Abstract
Pipe welding clamp including pipe end spacing means, for holding pipes disposed end to end for welding, and for spacing the pipe ends apart by a small distance during welding. Two clamp assemblies are provided, one for each pipe end, the clamp assemblies being individually expanded and set by forces applied through axially movable sleeve assemblies and toggles connected between the sleeve assemblies and radially disposed clamp elements. The sleeves are moved for setting and retracting the clamp assemblies by fluid cylinders. An additional fluid cylinder is adapted to move one clamp assembly relative the other to provide spacing between the pipe ends after setting of the clamps, the pipe end spacing being controlled at circularly spaced points around the apparatus by screw-adjustable spacing stops.
