An investigation was carried out to determine the weldability of Fe{sub 3}Al type alloys. Sigmajig tests of a commercial heat of FA-129 alloy indicate that hot-cracking may not be a problem for this alloy. Additionally, several new Fe{sub 3}Al based iron aluminides were evaluated for weldability. The preliminary results are encouraging and suggest that some of these alloys have comparable or better weldability than FA-129 based iron-aluminides. For the first time, successful welds, without hot or cold cracking, were made on 13 mm (0.5 in.) thick plates from a commercial heat of FA-129 using the proper choice of welding conditions and parameters.
