Abstract
In this research work an efforts has been taken to identify the effect of GTAW welding variables such as electrode angle with work surface, flow rate of shielding gas, arc gap and voltage affecting reactive performance variables such as hardness of weldment, tensile strength and toughness by impact test by using factorial design. Arc length is the important variables among all, which has the impact on the tensile, yield strength and elongation of the material and on hardness of the weldment. However, shielding gas has impact on toughness.
