Abstract

Abstract: Friction stir welding which is an innovatory method in solid joining procedure. FSW is energy effectual and most significant improvement in metal joining from decagon. Here, we are going to study mechanical properties about total nine friction stir welds of AA6063 are produced by following with three input independent processing parameters like spindle speed or tool rotational speed ,transverse feed and Tilt angle. The motto of this study is to find the optimum parametric values with FSW of AA6063 by using Taguchi technique.Different experimental tests are done on specimens of total nine AA6063 welded joints. We evaluate the mechanical properties values like Hardness, tensile strength, surface roughness by using hardness, tensile and surface roughness tests simultaneously. Finally we need to find the optimum values out of all tests. A High Speed Steel (HSS) was used for welding process. That tool having 6mm in diameter, 5.5mm as pin length and 18mm as shoulder diameter. Transverse feeds are 25, 35 and 45 mm/min; Spindle speeds are 950, 1250, 1450rpm; and the tilt angles are 0°, 0.5°and 1° are taken as the input parameters. We welded two metallic workpieces by using FSW. Each Aluminium workpiece is rectangle in shape having dimensions of 125X60mm and 6mm in thickness
