Description
Summary:This study relates about the mechanical properties, contour analysis and multi response method was implemented into the processed similar joint of AA5083 by friction stir welding (FSW). The processing was carried with fluted cylinder tool pin profile with applicable process parameters namely; tool traverse speed (35 to 65 mm/min), spinning speed (1250 to 1750 rpm) and tilt angle (1.5 to 2.50), respectively. These parameters are mingled together with Taguchi L9 array to reframe the parameters to identify the optimal by grey analysis technique. The hardness and tensile properties were employed with whole nine welded samples. The entire samples procured fine mechanical strength due to the influence of FSW parameters resulting in more plastic deformation was occurred in the stirred region. From the GRG responses the optimal FSW parameters are 50 mm/min of traverse speed, 1500 rpm of spinning speed and 2.5 of tilt angle. The hardness and tensile strength was attained more in those particular process parameters. Influence of tool traverse and spinning speed as major impact to improve their properties.
