| Abstract | The aim of the present study is to show the influence of different input parameters such as welding current, gas flow rate and welding speed on the mechanical properties during the gas tungsten arc welding of austenitic stainless steel 202 grade. The microstructure, hardness and tensile strength of weld specimen are investigated in this study. The selected three input parameters were varied at three levels. On the analogy, nine experiments were performed based on L9 orthogonal array of Taguchi’s methodology, which consist three input parameters. Analysis of variance (ANOVA) was employed to designate the levels of significance of input parameters. Current has the maximum influence on the output characteristics. Microstructure of weld metal structure shows the delta ferrite in matrix of austenite. |
