Ordered intermetallic alloys are a unique class of material that have potential for structural applications at elevated temperatures. This paper describes the welding and weldability of these alloys. Weldability of these alloys has been found to be a strong function of alloy composition, welding process and process parameters. Phase transformations associated with the weld thermal cycle play a critical role in determining their weldability. Defect-free welds have been produced in several of these alloys by careful selection of welding processes and welding parameters. 21 refs., 6 figs., 3 tabs.
