Tungsten inert gas welding is popular in some industries due to the possibility of obtaining good weld bead surface and high-quality joint without any weld defect. However, compared to many welding processes, shallow penetration of TIG welding hinders its applicability to weld thick components in one pass, thus the productivity is relatively low. An increased depth of penetration can be achieved by Activated TIG (ATIG) welding leading to overall reduction in number of welding passes, and thus increasing productivity. In the present work, attempts were made to find out the optimum flux mixture of SiO and TiO from various ratio of mixtures by carrying out 2 2 bead-on-plate welding on AISI 316 Stainless Steel specimens. From the obtained experimental data, suitable flux ratio was tried to find out giving the highest depth of penetration.Keywords
