In aerospace, automotive, manufacturing industries, welding has been widely used for engineering applications. Welding requires properties like corrosion resistance, wear resistance and hardness. The corrosion and wear rate depends on the atmospheric conditions and engineering applications. The welded AISI type 304L stainless steel is subjected to post weld heat treatment during welding process. This welding process suffers by ferrite and carbon contents. The filler ER310L is selected and welded with stainless steel (AISI type 304L) by Gas tungsten Arc welding (TIG welding) method. Satisfactory results are obtained from tensile test, hardness test, impact strength and microstructures, which makes it eligible for engineering applications. This research work elevates the corrosion resistance and mechanical properties of stainless steel (AISI type 304L) economically for the engineering applications.
