Abstract


The effect of process parameters of TIG welding like the present work focuses the findings of an experimental investigation into the effects of Welding current, Gas flow rate, Electrode diameter, and Root gap on the bead geometry of AISI-304. It is found that the process parameters considered affected the mechanical properties with great extent. Taguchi methodology is used to analyze the effect of each welding process parameters and optimal process parameters which obtained in order to get maximum ultimate tensile strength, Percentage elongation and Hardness of TIG welded AISI 304 stainless steel mainly four input parameter- Welding current, Gas flow rate, Electrode diameter, and Root gap are selected to analyze their effect by changing or varying them. In this study, maximization of response parameters has been identified by using design of experimental methods, Taguchi Analysis and Response surface methodology (RSM). The experiments were conducted using Taguchi’s L16 Orthogonal array in the design of experiment by considering Welding current (WC), Gas flow rate (GFR), Electrode diameter (ED), and Root gap (RG) as welding parameters. The model for the ultimate tensile strength, percentage elongation and hardness, as the function of response parameters, is obtained using the RSM. Finally, the result of developed mathematical model is examined by ANOVA. L16 Orthogonal Array technique is used to formulate the experiment layout and various processes. Conclude that the optimal input parameter setting for ultimate tensile strength, percentage elongation and hardness of TIG welded AISI 304.
