Abstract : Tungsten inert gas (TIG) welding widely known for the precise weld joint of the components due to controlled
heat input lacks the maximum weld penetration it can provide in a single pass for the steel joint, offers low -productivity and
cast to cast variation . Weld penetration being the most important parameter quantified by the aspect ratio (depth to width),
decides the number of passes required to weld a certain thickness of material. To overcome these limitations, optimized
mixture of certain oxides was developed for welding of 15mm plates of ASS which is applied by a paint brush followed by
TIG welding. Weld fusion zone having full penetration in a single pass achieving the aspect ratio even more than 1 was
observed. Various metallurgical and mechanical properties like hardness, toughness and tensile strength has been studied to
understand the effectiveness of activated flux GTAW of steels.
Keywords - TIG Welding ,Austenitic Stainless Steel, Activated Flux, Aspect Ratio, Arc Constriction, Marangoni Flow.
