Abstract

The conventional Tungsten Inert Gas (TIG) welding process is an autogenous welding process primarily used to weld thin metal sheets in the food processing and chemical industry. The process can weld almost all engineering materials but suffers from the limitation of slow speed and inability to weld thick sections. With the development of A-TIG welding, some of the drawbacks of traditional TIG welding have been addressed, where the activated flux is used to modify the welding arc, and the effect is shown in various aspects. The present investigative work aims to demonstrate the capability of A-TIG welding by using 316 L austenitic stainless steel as work material with CaO, TiO2, SiO2, Al2O3, and ZnO as flux. The input parameters like speed, voltage, and welding current were kept constant during the process to understand the effect of these fluxes on angular distortion and their subsequent comparison with conventional TIG welding. The work carried out shows that there is a reduction in the resulting angular distortion when fluxes are used.
