Abstract

Tungsten inert gas (TIG) welding is a fusion welding process having side range of applications in current industry. The TIG welding process parameters plays a very significant role in estimating the quality of a welded joint. So appropriate selection of welding process parameters is very much necessary to attain weld joint with increased tensile strength value. In the work, experiments were carried out on Austenitic Stainless Steel (AISI 304L) using Tungsten inert gas (TIG) welding process. In this study Butt welded joints have been made by using three levels of current, gas flow rate and nozzle to work piece distance. The quality of the weld has been estimated in terms of ultimate tensile strength of the welded specimens L9 orthogonal array of Taguchi`s experimental design method was utilized for optimization of welding current, gas flow rate and nozzle to work piece distance on welded joints.
