Abstract
Commercially pure titanium and type 304 stainless steel sheet was welded by using the resistance spot welding with a niobium insert as well as welding the specimen by different welding current. The tensile shear strength and the factors of affecting mechanical properties of the joints was investigated during observing the interfacial microstructure of the joint. The joint diameter and the joint shear strength increased with the increase of welding current. It is observed that the reaction layer generated on the nugget center near the side of the titanium which the component is -TiFe . The formation of the reaction layer have been observed in the nugget center near the side of Ti. The organization of the reaction layer is -TiFe, the lower the nugget center and nugget center near the stainless steel side are Fe and Fe2Nb eutectic structure. The tensile test results show that the joint fracture also called the interface fracture occurred in the side of SUS304/NB. The test results show that the intermediate layer prevents direct contact of titanium and stainless steel, directly inhibits the adverse reaction of the interface and improves the performance of the joint.
