Abstract: |
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. Generally, all welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters, excellent mechanical properties with minimum distortion. The Submerged Arc Welding (SAW) process finds wide industrial application due to its easy applicability, high current density and ability to deposit a large amount of weld metal using more than one wire at the same time. The quality of weld depends on bead geometry of the weld which in turn depends on the process variables. Welding input parameters play a very significant role in determining the quality of a weld joint. The joint quality can be assessed in terms of properties such as weld-bead geometry, mechanical properties, and distortion. |
