Aluminium alloys are the king in aircraft construction materials for aircraft industry since 1930. In the aerospace industry, 2014-Aluminum alloy after 2024-Aluminum alloy is the second most popular of the 2000-series. It is commonly forged and extruded. TIG welding can be a potential tool which is superior to other joining techniques, resulting in weight reduction with high strength. In order to find out the weakest locations of the joints and determine the optimum TIG welding parameters, this present work aims to demonstrate its TIG weldability and the emphasis is placed on the relations of the tensile properties and hardness to the welding parameters. To improve welding quality of Aluminium alloy (Al-2014) is welded with TIG welding system by changing different welding parameters. Effect of welding current and gas flow rate (Argon) on the tensile strength and hardness of the weld joint has been investigated. Optical microscopic analysis has been done on the weld zone to evaluate the effect of welding parameters on welding quality. Micro-hardness value of the welded zone has been measured at the cross section to understand the change in mechanical property of the welded zone. From the experimentation.
