Flash Welding experiments of TC18 Titanium Alloy were proceeded, then the microstructure and properties of Flash Welding joints of this alloy were studied.The results show that TC18 Titanium Alloy can be welded by the method of Flash Welding.The strength, elongation and impact toughness of the welding joints were respectively 87.1%, 68.5%and 15.1%of the basic metal, which have a low level without heat treatment after welding. If the heat treatment were proceeded after welding, the shrength of the joints was as the same as the basic metal, the elongation and impact toughness were respectively 52.7%and 35.5%of the basic metal.
