ABSTRACT:
Annular coupling members are disclosed for welding together sections of pipe used, for example, in the construction of oil pipelines, such annular coupling members containing annular bodies of exothermic materials such as "Thermite" material, and upon being ignited being capable of producing true welding of the interfaces between the coupler and a pair of pipes welded thereto or between the two pipes directly. These interfaces are beveled to accommodate variations in the diameters of the pipe sections so that any such variations will not adversely affect a true weld at these interfaces. Since the annular exothermic bodies are positioned adjacent the interfaces and interior of the annular coupler, the vast quantities of heat generated by igniting the "Thermite" bodies are directly utilized to form true welding of the interfaces, rather than being lost in varying degree to the material of separate reaction vessels, sprues, etc., as in prior art techniques.
