Abstract: The microstructure of weld metal was studied by means of XRD, SAED and EDS. High-temperature oxidation-resistance test and tensile test of joint were carried out. The results are as follows:the weld metal is Fe3Al. The tensile strength of the weld joint is inferior to that of the base metal, and the location of rupture is in the overheated zone. The oxidation-resistance property (900℃) of the base metal is superior to that of the weld metal.

Key words: TIG weld joint, Fe3Al alloy, high-temperature oxidation-resistance property
