Experimental Investigation of Friction Stir Welding on AA 5052 H32

摘要

Friction stir welding (FSW) is an effective mean of solid-state joining. It can weld thin plates with good weld joint that's why it is gradually replacing the riveting technique. In recent years, the application of Aluminium alloys gained a good attention because of its advanced mechanical, physical and tribological properties. Aluminium alloy 5052 H32 has very good corrosion resistance, weldability, high fatigue strength and moderate strength. In this paper, FSW of 2 mm thick AA5052 H32 plates were performed. The weld joint was tested for ultimate tensile strength (UTS) and Brinell harness number (BHN). Taguchi method was used to obtain the optimum process parameters and then ANOVA test was carried out to find the contribution and most significant process parameter effecting the ultimate tensile strength and Brinell hardness number.
