Numerical Study of Welding Distortion in SAW Welded Creep Strength Enhanced Ferrite Steel Joint

Abstract

The present work explains the welding of creep strength enhanced ferrite steels. A square butt joint sample was welded using submerged arc welding process. The best suitable welding parameters for good top and bottom reinforcement with good weld bead shape and geometry were decided. The butt joint was also modelled using the best suitable heat source model. The thermal profile results measured experimentally were compared with the numerically obtained results. The welding-induced distortion in terms of edge deflection was also measured experimentally and compared with numerically obtained one. It was found that results fairly matched for both thermal profile and distortion results.
