Effect of Friction Stir Welding Parameters on the Mechanical and Microstructure Properties on Dissimilar Welds

Friction Stir Welding (FSW) is a solid-state welding process used for welding similar and dissimilar materials. FSW is especially suitable to join sheet Al alloys and this technique allows different materials couples to be welded continuously. In this study, 6061 Al alloys and commercially pure Cu and Al alloy 6061 to Brass were produced at four different tool rotation speeds (710, 900, 1000, 1120 rpm) and different tool traverse speeds (10-60 mm/min) Copper and aluminium are important metals for the electrical industry due to their good electrical and thermal conductivity as well as high corrosion resistance and mechanical properties. Brass materials are widely used as engineering materials in industry because of their high electrical and thermal conductivity, high strength, and high corrosion resistance. The aim of present study was analogy of the microstructures and mechanical properties of friction stir welded joint of Aluminium to Copper and Aluminium to Brass plates in 4mm thickness.
