The present paper reports the results of butt-welding trials on cladded steel plates by utilizing arc-welding + laser beam hybrid coupling, with a single-pass technique and a single filler metal of proper composition. Test plates are made of steel, cladded with austenitic stainless steel. Welded samples were submitted to metallographic observations, X-ray EDS microanalysis, Vickers micro-hardness and tensile tests. The results allow to make an evaluation of the weld quality of the trial joints, aiming to investigate the possibility to carry out deep penetration welds in a single pass welding technique from one side and to assess welding parameters suitable to achieve a crack-free weld metal of satisfactory composition.

Abstract

The present paper reports the results of butt-welding trials on cladded steel plates by utilizing arc-welding + laser beam hybrid coupling, with a single-pass technique and a single filler metal of proper composition. Test plates are made of steel, cladded with austenitic stainless steel. Welded samples were submitted to metallographic observations, X-ray EDS microanalysis, Vickers micro-hardness and tensile tests. The results allow to make an evaluation of the weld quality of the trial joints, aiming to investigate the possibility to carry out deep penetration welds in a single pass welding technique from one side and to assess welding parameters suitable to achieve a crack-free weld metal of satisfactory composition.
