ABSTRACT OF THE DISCLOSURE A tool for positioning and retaining boiler pipe sections in aligned, spaced relation enabling the boiler pipe sections to be joined by heliarc welding incorporating a split block having opposed recessed therein which cooperate to define a passageway that is open at one side for receiving the adjacent ends of boiler pipe sections to retain the boiler pipe sections in alignment together with a spacing arrangement engaged with the opposed ends of the boiler pipe sections to retain the adjacent ends in adjustably spaced adjacent relation to enable heliarc welding of a portion of the adjacent ends of the boiler pipe sections. After the initial heliarc welding process has been completed around a portion of the periphery of the boiler pipe sections, the block is re- moved and the heliarc welding is completed around the periphery of the boiler pipe sections with the radial depth of the heliarc welding being substantially less than the radial thickness of the boiler pipe sections thus leaving a peripheral groove which is filled with conventional resis- tance type welding material using conventional welding techniques. The tool also includes an overcenter pulling device to pull the boiler pipe sections into aligned adjacent relation to that the block can be associated with the adjacent boiler pipe section.
