In the present research work an attempt is made to understand the effect of TIG welding parameters such as welding current, gas flow rate, welding speed, weld torch angle that are influences on responsive output parameters such as weld penetration, width, fusion area, micro hardness, and tensile strength of welding. Taguchi method is used to get the optimal parameters. In Taguchi method, L9 orthogonal array is used for experimentation. The effort made to investigate optimal machining parameters and their contribution for producing better weld quality and higher Productivity. After welding test for weld penetration, weld width, fusion area, tensile test, and micro hardness have been conducted. The significance of the factors on overall output feature of the weldment has also been evaluated by analysis of variance (ANOVA).
