Abstract

Gas Tungsten Arc welding (GTAW) process offers a potential for materials which are hard to weld. It is used to join thin sections of stainless steel and non ferrous metals like Al alloys and it is possible to obtain high quality weld for wide variety of metals and alloys. Gas Tungsten Arc Welding is generally used for fabrication of ferritic stainless steel components because it produces a very high quality weld. The majority of armour fabrication is performed by fusion welding process and they demand for highest welding quality. Shielded metal arc welding (SMAW) and the flux cored arc welding (FCAW) processes are widely used in fabrication of combat vehicle construction. Gas Metal Arc Welding (GMAW) is an effective technology used throughout the industry. It is used widely in advanced construction and equipment, especially in the automotive industry to join the parts. The combination of building materials which commonly uses aluminium and steel has high demand for welding technology. The GMAW welding parameters influence the quality, productivity and cost of welding joint. Austenitic stainless steels have been widely used as nuclear structural materials for reactor coolant piping, valve bodies and vessel internals because of their excellent mechanical properties. Ferritic stainless steels are good resistance to cyclic oxidation and to thermal fatigue, due to their low thermal expansion coefficient compared to austenitic stainless steels. However, these ferritic stainless steels generally have lower strength and lower resistance to isothermal oxidation and creep at high temperature. The current study presents some fundamental observations on the effect of welding processes on tensile, microstructure and corrosion behavior of the fusion zone, formed by AISI 304 (ASS) and AISI 430 (FSS) with AWS E308MoL austenitic stainless steel covered electrode, being a dissimilar welding procedure. Such welding configurations are widely used as an overlay of equipment in the petroleum and gas industries. The welding processes carried out in this experiment are Shielded Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), and Gas Metal Arc Welding (GMAW). Samples of the weld metals were conventionally prepared for the microstructural characterization for optical microscope. The tensile properties of the welded material are determined. Based on the results obtained, the optimum welding process for joining ASS and FSS is evaluated.
