  • Abstract In this study, the feasibility for the friction stir spot welding (FSSW) of SS400 low carbon steel to 6061-T6 aluminum alloy was investigated using the assembled-type and plain tools under the constant load of 13kN, the rotation speed of 1200 rpm. The temperatures between the steel sheet of thickness 2 mm and the aluminum alloy of 5 mm were measured during the FSSW process using K-type thermocouples. Results showed that the maximum interface temperature could achieve about 740°C using either the assembled-type or plain tools, but the temperature rise rate of assembled-type tool was higher than that of the plain tool. Furthermore, with increasing the thickness of aluminum alloy sheet, the temperature rise rate also decreased.
    The FSSW joint of steel sheet of 2 mm and aluminum alloy sheet of 10 mm could be fabricated by the assembled-type tool with the failure load of 22 kN at a dwell time of 45 s. However, under the same welding parameters, the heat generated by the plain tool is not enough to weld two sheets together.
