Abstract

Stainless Steel have functional characteristics in wide variety of applications such as nuclear reactor vessels, heat exchangers, oil industry tubulars and components of chemical processing units. Components have been used in such industries often required joining of materials with high thickness. There are many welding methods reliable for stainless steel welding. Among various welding methods, Submerged Arc Welding technique is familiar for high thickness welding .In this paper, Submerged Arc welding process and the effect of process parameter on quality of welding have been reviewed with various researches and discussed in detail because of its inherent benefits such as higher metal deposition rate, good strength of the joint and good surface appearance. Due to the above said desired properties, this welding process is extensively used in the fabrication of pressure vessels, pipe lines and off-shore structures. Welding flux constitutes nearly half of the cost in Submerged Arc Welding process. This welding process is often preferred because it offers high production rate, high melting efficiency and ease of automation. The review is concerned with factors influencing the quality of weld in stainless steel by Submerged Arc Welding and hope that it is very helpful for predicting the best welding conditions for stainless steel.
