DESIGN OF EXPERIMENT STUDY OF FRICTION STIR WELDING OF ALUMINUM ALLOY 6063

Abstract

Design of experiments using Taguchi L16 orthogonal array was applied to study the effect of different process
parameters on tensile strength of friction stir welded joints. Different process parameters namely tool rpm, welding speed
and pin diameter were studied. Tensile strength of welded 5mm thick aluminum alloy 6063 was determined and it was
observed that welding speed, tool rpm, tool shoulder diameter and tool pin diameter significantly affected the joint strength.
