Abstract
Among the arc welding processes, submerged arc welding (SAW) is preferred over other methods of welding because of its inherent qualities like easy control of process variables, high quality, deep penetration, smooth finish, capability to weld thicker sections and prevention of atmospheric contamination of weld pool. A layer of powdered flux generates a protecting gas shield as well as a slag to protect the weld region. The arc can be submerged below the flux layer & in general, is not noticeable throughout the welding process and to study the effect of flux constituents and basicity index on mechanical properties, hardness and microstructure of the weld metal.
