Abstract
This paper presents the evaluation of the mechanical properties and microstructure of the butt joint of AA 8011 produced by friction stir welding (FSW). The effect of the important FSW parameters on ultimate tensile strength (UTS) was determined using Taguchi L9 orthogonal arrays (OA) for analyzing the main effects and variance. From the results of the study, it was found that the most dominating factor affecting the UTS is welding speed, contributing 61.87%, followed by shoulder diameter with 18.02% and lastly tool rotational speed with 13.38%. The maximum UTS of 142.1 MPa higher than the base metal (BM) strength was attained at ideal settings of rotational speed at 560 rpm, welding speed of 100 mm/min and tool shoulder of 16 mm. The microstructure revealed dynamically recrystallized fine and equiaxed grains in SZ. The microhardness in SZ was found to be greater than the BM/TMAZ/HAZ.
