Mechanical properties of duplex stainless steel laser joints

[EN] This work presents the influence of welding parameters on the microstructural parameters and mechanical behaviour of welded joints. In doing so, we seek to establish the microstructural changes in the molten area and the heat affected zone, which will define the mechanical properties of the welded joints. This mechanical behaviour is evaluated by means of traction tests on welded test pieces and microhardness scanning of the heat affected zone. The authors would like to express their gratitude to the Asociación de Investigación de Óptica de la Comunidad Valenciana [Community of Valencia Optics Research Association] for the application of the laser welds and to the Spanish Ministry of Science and Technology for its support through Project MAT2001-1123-C03-02.
