Experimental Studies on Submerged Arc Welding Process

Abstract

The efficient application of any welding process depends on the understanding of associated processparameters influence on the weld quality. The weld quality includes the weld bead dimensions, temperaturedistribution, metallurgical phases and the mechanical properties. A detailed review on the experimental andnumerical approaches to understand the parametric influence of a single wire submerged arc welding(SAW) and multi-wire SAW processes on the final weld quality is reported in two parts. The first part dealswith the experimental approaches which explain the parametric influence on the weld bead dimensions,metallurgical phases and the mechanical properties of the SAW weldment. Furthermore, the studies relatedto statistical modeling of the present welding process are also discussed. The second part deals with thenumerical approaches which focus on the conduction based, and heat transfer and fluid flow analysis basedstudies in the present welding process. The present paper is the first part.
