Multi objective prediction and optimization of control parameters of Friction stir welding on Casted AlSi10Mg plates with Taguchi – Gray Relational Analysis

In this study, a 3 mm thickness of AlSi10Mg Casted alloy plates was used in the friction stir welding process. The experimentations were conducted Using design experiment to shorten number experiments and get optimal parameters by utilizing Gray relational analysis based on ultimate tensile hardness test results. Orthogonal array L9 (33) three main stages for each parameter, where tool velocity are 800, 900 1000 Rpm, feed 30,40,50 mm/min, plus axial load 300,400 500 Kg. Minitab 17 software. Relational is explore set process variables their effects strength weld plates. effectively welded, measured at room temperature. end result shows that rpm, 50 / min, then 400 kg dominant join
