Abstract: Friction Stir Welding (FSW) is the fumeless solid state welding technique. In which the materials are joined by placing nearby with tightly clamped and a rotating tool was inserted with longitudinal feed and an axial load. Due to the stirring action, the metals plastically deformed and joined together. In this research the base metals are AA7075-T6 and A384.0-T6 aluminium alloys of 6.35 mm thickness butt joints. A design matrix was developed by using MINITAB-17 Software and the FSW was carried out in a friction stir welding machine. By using the FSW specimens, the Ultimate Tensile Strength (UTS) was conducted and find out the lowest UTS specimen to do fatigue test. The fatigue strength of the base metals of AA 7075-T6, A384.0-T6 and the same combinations of lowest UTS, FSW specimens are tested and analysed in low cycle fatigue strengths of <105 cycles.
