Mechanical properties of duplex stainless steel laser joints

Abstract

[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.
