Analysis of Dissimilar Metal Welding of 1020 Mild Steel and 304 Stainless Steel

opining of divergent metals has discovered its utilization widely in power age, electronic, atomic reactors, petrochemical and concoction enterprises primarily to get customized properties in a segment and decrease in weight. Anyway productive welding of disparate metals has represented a significant test because of contrast in thermo-mechanical and synthetic properties of the materials to be joined under a typical welding condition. This causes a precarious slope of the thermo-mechanical properties along the weld. An assortment of issues come up in disparate welding like breaking, huge weld leftover anxieties, relocation of molecules during welding causing pressure focus on one side of the weld, compressive and tractable warm burdens, stress erosion splitting, and so on. Weld lingering pressure and warm pressure have been investigated for unique metal welding of 304 treated steel to 1020 mellow steel accepting 302 tempered steel as the filler metal. Likewise taking strain created as a file the powerlessness of the welded joint to pressure erosion splitting have been considered. It is discovered that when the filler metal is supplanted by Inconel 625 critical improvement is acquired in the welded joint as far as decrease in pressure created and stress consumption splitting. Additionally the issue of carbon relocation is disposed of by the utilization of Inconel 625 as a weld filler metal because of the obstruction of nickel-based composites to any carbon dissemination through them.
