Experimental study and taguchi optimization of process parameter on mechanical properties of A319 aluminum alloy using friction stir welding

Abstract

The main objective of this abstract is to investigate the effect of welding parameters and the mechanical properties in the study of FSW. In this process, the mathematical model was developed by creating the Taguchi design methodology with three parameters, three levels, and 9 runs and it was also used to develop the relationship between those parameters. It can be produced and using a wide range of process parameters and its recommendation for producing the best joint tensile properties. Taguchi Method is used for the optimization of FSW process parameters for the joining of A319 Aluminum alloys. Taguchi method is signal to noise ratio (S/N) analysis that suggests the maximum tensile strength is reached when rotation, traverse speed, and tool pin diameter were chosen as 900 rpm, 40 mm/ min and 5.5 mm pin diameter respectively. ANOVA is used to find out the importance of the parameters. FSW can produce a satisfactory result of 141.05 MPa tensile strength and 112.04 MPa yield strength. FSW can weld A319 plates with a joint efficiency of around 75%.
