dc.description.abstractABSTRACT newlineThe structural material identified for the work is 15CDV6 steel belongs to the category of newlineHigh Strength Low Alloy (HSLA) family. HSLA steels vary from other alloys in the context; newlinethey are not made to meet a specific chemical composition but rather to specific mechanical newlineproperties. The material finds its application in the fabrication of rocket motor casings, newlinepressure vessels etc. and features excellent strength, mechanical properties, high strength newlineto weight ratio, good corrosion resistance, better workability and weldability. Several newlinecomponents in the space program are developed by one of the candidate process named newlineas Tungsten inert gas (TIG) welding process. Arc welding process named as Gas tungsten newlinearc welding (GTAW) also called as TIG welding, which produces the weld by deploying newlinethe non-consumable tungsten electrode. Inert shielding gas (argon or helium), are utilized newlinefor the protection of the weld area from atmospheric contamination or by generally utilizing newlinethe filler metal. The full penetration for joints thicker than 3 mm is obtained usually by the newlinemultiple pass TIG welding with filler wire. In multiple pass welding, because of the uneven newlinethermal cycles, there may be a generation of tensile residual stresses within the weld zone newlineand directs the crack formation and angular distortions also occur during this process. These newlinelimitations can be overcome by the narrative TIG welding variant named Powdered Flux TIG newlinewelding and thereby it is utilized in the learning of attaining complete penetration in a single newlinepass. Further, this research work contributes some advanced model of TIG welding with newlinesome new mathematical concepts. The main objective of this research work is to attain a full newlinepenetration over the single pass autogenous (without filler wire) TIG welding by searching newlinethe process parameters optimally with respect to the minimum potential heat input in 6.2 newlinemm thickness in 15CDV6 steel. newlineThe primary contribution of this research work is the selection of maximum and newlineminimum level of GTAW paramet
