Abstract
Modernization of TIG process can be done after thoroughly examining its various parameters and their effect on the strength of the welds produced. Welded stainless steel finds application with aerospace, nuclear and underwater industries. Main objective of the experiment is to optimize the factors affecting the tensile strength of austenitic stainless steel at varied welding parameters. SS202 and SS410 stainless steel of 3 mm thick is taken for experiments. The Taguchi method is applied using input parameters viz. current, gas pressure and weld rate and the desired response output namely ultimate tensile strength was evaluated. It is clear that there are highly non-linear relationship between current & UTS and welding speed & UTS.
Keywords: TIG welding, stainless steel, Taguchi method, ultimate tensile strength.
