Experimental Investigation of Welding Process Parameters on Mechanical Properties for TIG Welded Austenitic Stainless Stell 304 Joints

Abstract

Austenitic stainless steels have been used widely by the fabrication industry owing to their excellent high temperature and corrosion resistance properties. Some of the typical applications of these steel include their use as nuclear structural material for reactor coolant piping, valve bodies, vessel internals, chemical and process industries, dairy industries, petrochemical industries etc. Out of 300 series grade of these steels type 304 SS is extensively used in industries due to its superior low temperature toughness and corrosion resistance. This work aims at analysis for effect of selected welding process parameters on mechanical properties of TIG welded Austenitic stainless steel 304 plate butt joints. After TIG welding; mechanical tests are done on welded joints.
