Abstract

The present research work deals with parametric study and optimization of tungsten inert gas welding process (TIG) on Duplex Stainless Steel (DSS2205).The present investigation is to find out the best influence of welding current, welding speed, and gas flow rate on mechanical properties more specifically the tensile strength.MINTAB  software was used for designing, analyzing and optimization of the welding process.Taguchi L9 orthogonal array method was employed to optimize the welding process parameters for improvement of mechanical properties of weld bead such as tensile strength without any alteration of its corrosion resistance. Three welding parameters was selected as a study variablesand their three levels were selected and design of experiments was implemented as per Taguchi L9 array approach. Analysis of Variance (ANOVA) applied in investigation. Results have been analyzed using tensile strength  as a response variable  of the prepared welding jointsusing Taguchi L9 array approach The tensile strength test results showed that as welding current is increased the tensile strength was decreased, while increasing gas flow rate caused an increase in tensile strength up to rate of 13 L/min then decreased. Finally a regression model is developed which relate the TIG welding factors with the response variable which is the tensile strength which can be used in the future to predict the welding setting which would produce a joint with a specific strength.
