Abstract

Joining of dissimilar metals is using extensively in power generation, petrochemical, nuclear reactors and chemical
industries mainly to get custom built properties in a component and weight reduction. However efficient welding of dissimilar
metals has faced a major challenge due to difference in chemical and mechanical properties of the materials to be joined
under a common welding condition. A variety of problems come up in dissimilar welding like cracking, large weld residual
stresses, Voids & Porosity, oxides formation, compressive and tensile stresses, stress corrosion cracking, etc. In the Present
study, Stainless Steel grade 304 was welded with Mild Steel grade 1020 by Tungsten Inert Gas (TIG) welding process by
taking different stainless steels as the filler metals i.e. ER SS308L, ER SS309L and ER SS316L. The macrostructure of joints
were analyzed and tensile strength of dissimilar metal joints was investigated. The results were compared for different joints
made by different filler metals and it was observed that TIG welded dissimilar metal with filler metal used ER SS309L have
better physical properties than others.
