The weldability of commercial pure titanium to 304 stainless steel by resistance spot welding was investigated by means of tensile shear test and macro- and microstructural observations. The results obtained are as follows : 1) It is rarely successful to obtain reliable joint strngth by directly welded titanium to 304 stainless steel because of the formation of brittle intermetallic compounds mainly composed of TiFe_2. 2) Ductile weld joints are produced by an application of the insert metal sheets of 1100 aluminum and their maximum tensile shear strength reaches about 350kg/spot. 3) In case of the weld joints having the insert metal sheets, an intermetallic compound layer is formed between 304 stainless steel and 1100 aluminum but the ductility of the joints is not lost unless the compound layer grows and fills up the nugget in the insert metal sheets of 1100 aluminum.
