To improve the mechanical properties of the weld structure and to reduce the manufacturing costs, the welding parameters of TIG welding process needs to be optimized. The present investigation focused on the optimization of the procedure parameters of TIG joining procedure. AISI 304 materials selected as a base metal. The dimension of specimen is 200 mm × 50 mm × 3 mm. The specimen was butt-welded by the TIG welding method. Selection of input parameters is based on their significance effect on the mechanical properties of weld structure. The selected input parameters are Voltage, Current, Gas flow and root gap. The number of experiments carried out is 27, which is designed by Taguchi L27 orthogonal array using four factors and 3 levels by MINITAB-17software. Conducting tensile strength test checks the final weld quality
