Abstract
The present study relates investigating the effect of four kinds of fluxes, SiO2, MnO2, TiO2, Al2O3,and no flux was used in activated-pulsed tungsten inert gas welding (A-PTIG) process on ultimate tensile strength (UTS), yield strength (YS), elongation, and weld morphology of Duplex Stainless Steel SS2205. This study involves a novel variant of the Activated-pulsed TIG welding process, was applied to 6 mm thick DSS 2205 plate through a thin layer of flux to join plate-to-plate using a butt joint. The oxide fluxes used were employed in powdered form. The experimental results indicate that using SiO2, MnO2, TiO2, and Al2O3 fluxes lead to a significant increase in the capacity of TIG welds. The employed activated -Pulsed TIG welding showed that increase in joint penetration and weld depth-to-width ratio, thereby reducing the angular distortion of the weldments. Weld morphology of all the weld was studied and correlated with the mechanical properties.
