TIG welding is highly regarded because of quality and applicability; the process can be applied to several industries and aid in the creation and repair of many items. This form of welding is common in the aerospace, automotive, repair and art fields. To improve welding quality of SS 304 L & SS 410 using TIG welding system, by which welding speed can be control during welding process. Surface roughness and tensile strength of the weld joint has been investigated on the weld zone to evaluate the effect of welding parameters on welding quality. Micro-hardness value of the welded zone has been measured at the cross section to understand the change in mechanical property of the welded zone. At lower welding speeds, strength is more due to more intensity of current. With the increase in current, tensile strength of the weld joint increases. Comparison between methodical model and experimental results is in good agreement indicating that the developed models can predict the responses adequately within the limits of welding parameters being used.
