Investigation of Welding Process Parameters In Friction Stir Welding of AA1100 Alloy Using Taguchi Technique

Friction stir welding (FSW) of aluminium alloy AA1100 is investigated in this work. The process parameters considered the work includes; tool tilt angle, pin geometry, rotational speed and speed. tensile strength, temperature hardness are as responses selection optimum for maximizing minimization demonstrated using Taguchi technique Response surface methodology. Four levels selected L16 orthogonal array used to perform 16 experiments designed by design software. Aluminium alloys thickness 2mm chosen experimental specially which made up high steel material Stir Welding process. Tool pins various shapes study. ANOVA analysis carried out every response S/N ratio determined main effects plots signal noise plotted discussed. microstructure grain size infl uences strength weld joint. It observed that angle provides very less uence determination during FSW alloy. increasing penetration into specimen will increase a result it leads an temperature.
