Analysis of TIG Welding Process on Mechanical Properties and Microstructure of Aa6063 Aluminum Alloy Joints

Present work pertains to testing of mechanical properties and microstructure of AA 6063 Aluminium alloy joints by Tungsten inert gas (TIG) welding. By varying weld current and maintaining all parameters constant hardness, impact and tensile strength of the welded joints are tested and finally, microstructure details are analyzed. The results showed mechanical properties linearly varies with increase in weld current
