The research focused on the application of the tungsten inert gas (TIG) welding method on mild steel metal materials and its optimization of the welding input factors along with its mechanical response parameters using the response surface method (RSM). The study has reviewed many research works alongside works of literature related to the study, and also revealed that the specific studied mild steel weld bead geometry mechanical properties on its weldment have not been studied to the best of the researchers' knowledge. The material under study is IS 2062, why the method applied for the analysis is the response surface method of optimization. The result shows the optimal solutions of both the input factors and the response parameters. The optimization results show that the optimal solutions for input process factors are: a gas flow rate of 16.00m3/s, welding speed is 113.221m/s, welding voltage is 18.00V, and welding current is 217.914A. The optimization results for the response parameters are; 344.628MPa for Hardness strength, 331.042 MPa for Yield strength, 25.272% for percentage Elongation, 452.780 for ultimate tensile strength, and 409.484 MPa for shear stress, and 118.00 J for impact energy response. The overall desirability of the models developed to achieve the optimal solutions result is 78.41%. The results will serve as bases for mild steel companies and industrialization. The research will also serve as a decision-making system in engineering and industrialization.
