Abstract
In recent years, composite materials have gained more and more attention in aerospace, automotive and structural applications. In
many engineering applications, high strength-weight ratio of materials are important while designing the components. Now a
days, to fulfil the above requirements conventional materials are replaced by composite materials. In present work, stir casting
method is used for uniform distribution of the reinforcement material (SiC) in Aluminium as a matrix material. Friction stir
welding (FSW) is a relatively new solid-state joining process. In particular, it can be used to join high-strength aerospace
aluminium alloys that are hard to weld by conventional fusion welding. For analysis, L9 orthogonal array is used with four
different variables (Wt % of Sic, welding speed, tool rotation speed and tool geometry) for the analysis of UTS. ANOVA is
performed for the optimization of the process parameters.
