Review on Optimization of Submerged Arc Welding Process

Impact of Welding Parameters on the Quality of Submerged Arc Welding

Abstract

The present review is on optimization of submerged arc welding process. The physical and mechanical properties of the weld metal vary with different welding parameters such as arc voltage, welding current and welding speed. Hence it is essential to study and optimize these factors to achieve high quality welding procedures. Engineers in the manufacturing industries and researchers always face the problem of selecting appropriate or optimum combinations of input welding parameters for achieving the required weld quality. Optimal control of the welding parameters will give the best properties of the weld and reduce weld defects. Weld strength is directly proportional to the penetration depth. Hence it is essential to study the effect of voltage, welding current and welding speed on depth of penetration, weld bead width and reinforcement height of weld.
