Because of a special interest in Alloy 718, the Defense Metals Information Center has summarized information on the welding and brazing of the alloy. Two principal resons for the interest in this alloy are its good formability and its good weldability, expecially under restraint. The greater portion of the fusion welding of Alloy 718 has been done by the gas tungsten-arc (TIG) process. A discussion of welding atmosphere, filler metals, heat treatment of welds, welding under restraint, and weld toughness is presented in the section on fusion welding. Information is also presented on resistance welding and electron-beam welding of Alloy 718. The final section of this report deals with the brazing of Alloy 718.
