To Study the Effect of Process Parameters on Mechanical Properties of Friction Stir Welded AA 6063 Aluminium Alloy

Friction stir welding is widely used in joining aluminium alloys in industries, especially, the shipbuilding, aerospace, mass transportation and automotive and other commercial importance. This process is considered as “green technology� due to its energy efficiency, environmental friendly and versatility. Friction stir welding was carried out using a vertical milling machine on aluminium 6063 alloy. The tool material and geometry were carefully chosen and prepared using lathe machine. Important process parameters that control the quality of the weld and rotation speed (rpm), transverse speed (mm/min), tool depth (mm) and tool tilt angle and these process parameters were optimized to obtain defect free welding joints. it is observed that, during the friction stir welding, extensive deformation takes place at the nugget zone and the evolved microstructure properties of the joint. The aim of present study is to understand the mechanical properties and study wear test of Friction Stir Welding of AA 6063. In order to study the mechanical properties, we applied Micro Vickers hardness test and tensile test on FSW AA 6063 Aluminium alloy.
