Conference Name :
The aim of this work is to study the mechanical properties that affect the welding joint of metals. Stainless Steel 304 was welded to Mild steel using a TIG welding which also known as Gas tungsten arc welding (GTAW) or tungsten inert gas (TIG) welding The weld area and electrode is protected from oxidation and other atmospheric contamination is prevented by an inert shielding gas (argon or helium). Metals welding have great scope in advanced technology that includes high hardness, high strength and corrosion resistance properties. The combination of stainless steel has got large number of application in industry such as nuclear plant, and heat exchanger assembly etc. Due to the fact that low cost of mild steel and corrosion resistance property of stainless steel, all these application requires welding of the two which can perform the desired service requirement of the industry. The results indicate the optimum value of current and voltage which will be applied to developed to maximize the mechanical properties of welding the stainless steel 306 and Mild steel.
