Duplex stainless steel, Welding, Microstructure, Mechanical propertiesAbstract
TIG welding of two different duplex stainless steels is carried out. Arc-discharge on base-material plates by means of the TIG technique without filler metal and varying the energetic conditions (E.N.A.) has been performed, A comparative study concerning the microstructural evolution as well as mechanical properties is carried out, The relation between hardness profiles, the microstructural variations and the ferrita δ concentration is established. Further, the above mentioned properties are related to the E.N.A. for each welded joint.
