Evaluation and Optimization of Process Parameters of Tig Welding

Abstract

Tungsten inert gas welding is an advanced technique for bringing conjoins between ferrous and non-ferrous metals. TIG welding has abundant benefits in joining of dissimilar metals while considering certain parameters such as  zone with low heat, Min slag. The intension was to investigate the effect of TIG welding parameters acting along the surface of Aluminium-6061. The Taguchi method        used to conduct the experiments. The voltage, current, stand-off distance and gas flow rate were the attributes considered for the process. The  Joints of the samples were tested by the Universal Testing Machine  and welded joints were tested for hardness using the  Rockwell Hardness testing machine. The experiments were conducted with an intension to optimize the welding conditions so as to maximize the hardness and tensile strength
