Abstract: Welding is one of the most popular methods of metal joining process. Tungsten Inert Gas welding process is an important process in much industrial experience, for joining ferrous & non-ferrous metals. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This doesn’t ensure that the selected welding process parameters can produce the optimal or near optimal weld pool geometry, for that particular welding machine and environment. This paper discussed the effect of welding variables on the microstructure analysis, mechanical properties of welded 5 mm thick of 301 stainless steel plate and 1020 mild steel plate, welded using the Tungsten Inert Gas (TIG) welding method . However efficient welding of dissimilar metals has posed a major challenge due to difference in thermo mechanical and chemical properties of the materials to be joined under a common welding condition. So in this project weld hardness and the microstructure have been analyzed for dissimilar metal welding of 301 stainless steel to 1020 mild steel taking 302 stainless steel as the filler metal. Similarly taking strain developed as an index the susceptibility of the welded joint to stress corrosion cracking have been studied. It is found that when the filler metal is replaced by 301 stainless steel significant improvements is obtained in the welded joint in terms of reduction in stress developed and stress corrosion cracking.
Keywords: Hardness, Microstructure, mechanical properties, Parameters comparison, TIG welding
