Abstract

The practice of stainless steel in the industry is persisting in growing regularly. Investigators conducted different experiments for various grades of steels. The use of austenitic stainless steel (304L) and stainless steel (316L) has been increased noticeably in building up of railway wagons and modern boilers where corrosion resistance areas and mechanical properties like tensile strength, toughness, hardness, etc., of the welded zone plays a major role. The objective of the present paper is to investigate the mechanical properties on dissimilar metal of austenitic stainless dteel (304) and stainless steel (316) joining under TIG welding process. Single V-groove butt welding process was carried out using gas tungsten arc welding (GTA) and shielded metal arc welding (SMAW). The experiment was conducted with identical parameters such as current, gas flow rate, and nozzle-to-plate distance, and their effects were investigated. ASTM standards are adopted for the weld specimens, and the results have been discussed.
