Resumen: TI1e aim of this work was to check the aplicability of the tension test on the fracture toughness detennination of weld joints. Submcrged are wclds were perfonned on a high strength quenched and tempered steel RQT 701 (British Steel Corporation) with a couple OK Flux 10.62/0K Autrod 13.43 with hcat inputs of 2 kJ/mm and 5 kJ/mm. Tension test specimens were obtained from the weld plates, transversely to the weld direction. In the absence of weld defects plastic deformation occurs in the weakest zone of the weld. Tension test showed a reduced capacity to discriminate the touglmess of welds performed with different heat inputs.
