Joining three sheets by resistance spot welding was an increasing trend in automotive assembly. Effect parameter of welding such us voltage and welding times to physics and mechanical properties resistance spot weld joint dissimilar metals three sheets 316L, SS 400, J1 was determined. Electroda pressure was kept constant in this result. The parameter of welding was used in this experiment were 2.02; 2.30; 2.67 V and 3; 4; 5; 7.5 s. As a result of the experiment, it was determined that voltage 2.67 V and welding times 7.5 s result tensile shear load was 11.19 kN with pull out failure mode. The increasing of voltage and welding times cause higher fusion zone size along sheet/sheet interface. The area of HAZ was increased because there was an increase in the welding times. The higher hardness was a nugget because grain was formed columnar.
