ESCO Tool offers a joint alignment fixture for easier use than a welding vise.

A welding joint alignment fixture that is easier to use than a welding vise, the ESCO HOG TIE Boiler Tube Weld Alignment Clamp consists of one side with two through-holes and a matching side with threaded inserts which accept two bolts that draw them together.  Easy to set-up and use, this clamp aligns the pipe or tube perfectly and exposes their ends for tack welding prior to removal in order to complete the entire joint weld.

O.D., the Esco HOG TIE Boiler Tube Weld Alignment Clamp is made of precision machined high strength steel.  This pipe alignment tool is available by itself or as a kit with an impact wrench and socket, four 0.5 in. bolts, two spare through-hole inserts, two spare threaded inserts, and a metal carrying case.
