The purpose of this experimental investigation is to determine how the root gap and groove angles affect the tensile strength of TIG-welded SS304 weld joints. The welding parameters for connecting 304 stainless steel using Gas Tungsten Arc Welding (GTAW) were extensively studied using the Taguchi method and a l9 orthogonal array. The evaluation of the mechanical properties of the welded joints is the main goal of this study. The analysis specifically looks at the effect of the Root Gap and Groove Angles on the response variable, which probably represents the tensile strength of the TIG-welded SS304 joints. The analysis specifically looks at the effect of the Root Gap and Groove Angles on the response variable, which probably represents the tensile strength of the TIG-welded SS304 joints. According to the results, Root Gap has a greater percentage of contributions (64.22%) than Groove Angles (43.64%), indicating that it dominates the response. The optimal root gap and V-groove angle for producing the highest tensile strength (621.06 MPa) were found to be 1 mm and 45°, respectively. These findings contribute to improvements in welding procedures for numerous industrial applications by providing useful information on boosting the mechanical performance of TIG-welded SS304 joints and optimizing welding parameters.
