Industrial aluminum alloys generally present low weldability by fusion welding methods because of the sensitivity to weld solidification cracking, vaporization of strengthening alloys and other defects in the fusion zone. Friction stir welding (FSW) can be deployed successfully with aluminum alloys. We presented the effect of post-weld heat treatment (PWHT) on the microstructure and hardness properties of Aluminum. Semi solid plates were butt-welded by FSW at a rotation speed of 1200, 1000, 500 rpm, welding speeds of 300 mm/min. The heat-treatable alloys Al-Fe-Zn-Mg-Cu develop their properties by solution heat treating and quenching, followed by either natural or artificial aging. The heat-treatable alloy may also be annealed to attain maximum ductility. This research was the study in post weld heat treatment (PWHT) that affected to hardness properties and microstructure. The material in testing is aluminum alloy. Post weld heat treatment temperatures were set at 400 0C and Post weld heat treatment times were controlled at 20 and 24 hours. The welded specimens were tested by hardness testing machine. This can result in increased of hardness. These results can use as data information in future for improve post weld heat treatment properties.
