      Abstract

      Dissimilar FSSW (Friction Stir Spot Welding) is the development of solid state point welding to joining different type materials as an alternative to fusion welding from RSW (resistance spot welding). The addition of Zn to FSSW has the advantage to increase the strength of the welding joint by the occurrence of Zn diffusion reactions at the interface. The purpose of this research is to know the effect of variation of rotational speed (1000 rpm, 1200 rpm, 1600 rpm and 2000 rpm) and variation of flat tool diameter (10 mm, 12 mm and 14 mm) to Zn distribution in AA 5083 H321 and galvanized steel with the FSSW method. A constant variable of this research is Depth of plunge 2,7 mm, dwell time 3 second and penetration rate 0,9 mm / sec. This research used a lap joint configuration with AA5083 H321 (3 mm) plate placed on the top and galvanized steel plate (1 mm) placed at the bottom. As the speed increases, more diffusion of Zn flow to the edge of stir zone. The highest Zn flow is at 2000 rpm with a flat tool of 14 mm (2.114 mm). As the flat tool diameter increase, farther Zn distribution distance of the edge stir zone followed by the increase of Zn density to Al. The 2000 rpm speed variation with 14 mm flat tool has the furthest distance with 1.17 mm and 0.3% Zn density.
