Parametric Optimization for Tensile Strength of Friction Stir Welded Aluminium Alloy AA1100 using Taguchi Method

Saleh Abdullahi, Akor Terngu

Abstract


Friction stir welding of AA 1100 was conducted across a defined parameter range, leading to the establishment of optimal settings for Tensile Strength (TS). The tensile tests, performed using an Instron Universal Testing machine, yielded TS values ranging from 48 MPa to 98 MPa. Employing the higher-is-better criterion for maximum TS, the Taguchi experimental method was applied to optimize various process parameters and identify dominant factors. The optimal parameters were determined as a rotational speed of 900 rpm, traverse speed of 25 mm/min, and tilt angle of 2 degrees. Through analysis of variance, it was revealed with 90% confidence that rotational speed exerted the most significant influence on tensile strength, contributing over 72%. Additionally, the tilt angle contributed over 24%. Conversely, the traverse speed demonstrated an insignificant effect on tensile strength within the parameter range explored in this study.
