摘要：
In this study, weldability and mechanical properties of resistance spot weld bonding were investigated when adhesives with different properties were used. The results show that weldability is improved in resistance spot weld bonding when the adhesive is discharged from the weld zone by using a multi-stage current application technique. In terms of mechanical properties, weld-bonded joints using high-strength adhesives showed improved strength because both the weld and the adhesive are subjected to loads. On the other hand, when a low-strength adhesive is used, the adhesive and the weld fail separately, and the CTS is not improved. In addition, in the resistance spot weld bonding of Fe-Al, the IMC formation area is expanded, and the CTS is improved by using a 3-stage current application.
