PURPOSE: A method for welding gamma-aluminite based material employed as a raw material for turbine blade of air-craft without solidification-cracking where intermetallic compound of gamma-aluminite based (Al content is 45-50atom.%) is welded while applying compressive stress (1-10kgf/mm¬2) in the parallel direction along the joining line of two metal specimens. CONSTITUTION: In the method for welding gamma-aluminite based material, the gamma-aluminite based material is selected from Ti-Al intermetallic compound, Ti-Al-X intermetallic compound (wherein X is Mn, Cr, V) and Ti-Al-X-Y intermetallic compound (wherein Y is Nb).
