“…Resistance spot welding is a solid state joining technique applied for almost all known metals, and one of the oldest electric welding processes in use today. The weld is made by the combination of heat, pressure, and time [2][3][4] . So this method can avoid above issues to a certain extent.…”

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 α-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 α-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.

The study is concerned with the bimetallic plate composed of the Ti6Al4V and Inconel 625 alloys. The alloys were joined together using the explosive method with the aim to produce a bimetallic joint. The structure and the mechanical properties of the as-received raw Ti6Al4V and Inconel 625 alloys, the Ti6Al4V/Inconel 625 joint, and the joint after annealing (600°C for 1 h) were examined. The samples observations were performed using a light microscope and a scanning electron microscope. The mechanical properties were estimated by microhardness measurements, tensile tests, and three-point bending tests. Moreover, the deformation strengthening of the metals and the strength of the joint were analyzed. The explosive process resulted in a good quality bimetallic joint. Both sheets were deformed plastically and the joint surface between the alloys had a wavy shape. In the area of the joint surface, the hardness was increased. For example, the annealing at 600°C for 1 h resulted in changes of the microhardness in the entire volume of the samples and in changes of the morphology of the joint surface. In three-point bending tests, the samples were examined in two opposite positions (Ti6Al4V on the top or Inconel 625 on the top). The results indicated to depend on the position in which the sample was tested.

“…However, there are some difficulties to weld titanium and stainless steel, because of the great differences in thermal, physical, and chemical properties. Hence, some welding methods have been studied in the last few years to obtain a sound joint, such as electron beam welding [1], diffusion bonding [2], soldering [3] and explosive welding [4]. Although the joints acquired by the above means show reasonable performance to a certain extent, the performance of the joints still need to be further improved.…”

Commercially pure titanium and stainless steel sheets were welded using resistance spot welding with interlayer of Nb. The interfacial microstructure was observed, the effects of welding current on nugget diameter and tensile shear load were investigated deeply. The results show that the interfacial reaction products were consisted of Nb and FeNb eutectic structure. The joint with the maximum tensile shear load of 5.61kN was obtained at the condition of 10 kA. It reveals that it is effective to weld titanium and stainless steel using resistance spot welding with an interlayer of Nb.
