Welding processes that employ an electric arc are the most prevalent in industry are Shielded Metal Arc Welding, Gas Metal Arc Welding, Flux Cored Arc Welding, Submerged Arc Welding and Gas Tungsten Arc Welding. These processes are associated with molten metal. Molten metal reacts with the atmosphere so that oxides and nitrides are formed. All arc welding processes employ some means of shielding the molten weld pool from the air. The Submerged Arc Welding process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. The quality of weld depends on bead geometry of the weld which in turn depends on the process variables. Submerged Arc Welding (SAW) is one of the major metal fabrication techniques in industry due to its reliability and capability of producing good quality weld. The ability to join thick plates (as thick as 1.5 inch) in a single pass, with high metal deposition rate has made this process useful in large structural applications. It is one of the most widely used processes for fabrication of pipes, thick plates, pressure vessels, marine vessels, rail tanks, ships, heat exchangers, offshore structure etc. This process is commercially used for welding of low carbon steel, high strength low alloy steel, nickel base alloys and stainless steel. It is possible to weld thin sheet of steels at over 5 m/min with minimum emission of welding fume. Selection of process parameters has great influence on the quality of a welded connection. In this paper the overall review on influence of Process Parameters in submerged arc welding during the multipass phase is presented. It is necessary to study on Process Parameters of submerged arc welding for getting quality and effective welding. Generally, all welding processes are used with the aim of obtaining welded joint with the desired weld-bead parameters, excellent mechanical properties with minimum distortion
