Experimental and numerical study of submerged arc welding induced thermal history residual stresses distortion and weldment characterization

Abstract

Submerged arc welding is a fusion welding process which is characterized by its high deposition deep penetration high productivity and smooth finish especially for down hand position welding It is generally used in fabrication of large structures which involves the formation of residual stresses and distortion The purpose of the present work is to study the thermo mechanical behaviour and weldment characterization of the submerged arc welded joints and development of suitable mitigation tec
