Effect of Activated Flux on Properties of SS 304 Using TIG Welding

This research presents the study on Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) used as activated fluxes to find out its effects on SS 304 in Tungsten Inert Gas (TIG) welding. The Ultimate tensile strength, percentage elongation, Penetration depth, width and depth to width ratio of SS 304 have been studied. The experiment indicates that the use of MnO2 and Fe2O3 as flux increases the weld penetration depth and decrease the weld width. The use of ZnO and MgCl2 as flux also shows a little increase in penetration depth and weld depth to width ratio as compared to conventional TIG process. The ultimate tensile strength and the percentage elongation have been increased in Activated Flux TIG welding.
