This paper discusses the use of Taguchi technique for maximizing the tensile strength of friction stir welded cast aluminium alloy A413. The experiments have been conducted using Taguchi's experimental design technique. The friction stir welding (FSW) process parameters namely tool rotational speed, welding speed, axial force play a major role in deciding the weld quality. The effect of process parameters on tensile strength is evaluated and the optimum welding condition for maximizing the tensile strength is determined. The analysis of variance and the signal to noise ratio of robust design are employed to investigate the influence of process parameters on the tensile strength of friction stir welded A413 aluminium alloy. To correlate the process parameters and the measured tensile strength, a mathematical model has been developed by multiple linear regression analysis. The developed mathematical model is found to be very useful for predicting the tensile strength of friction stir welded A413 aluminium alloy.

Abstract


This paper discusses the use of Taguchi technique for maximizing the tensile strength of friction stir welded cast aluminium alloy A413. The experiments have been conducted using Taguchi's experimental design technique. The friction stir welding (FSW) process parameters namely tool rotational speed, welding speed, axial force play a major role in deciding the weld quality. The effect of process parameters on tensile strength is evaluated and the optimum welding condition for maximizing the tensile strength is determined. The analysis of variance and the signal to noise ratio of robust design are employed to investigate the influence of process parameters on the tensile strength of friction stir welded A413 aluminium alloy. To correlate the process parameters and the measured tensile strength, a mathematical model has been developed by multiple linear regression analysis. The developed mathematical model is found to be very useful for predicting the tensile strength of friction stir welded A413 aluminium alloy.
