AB  - Duplex stainless steels (DSSs) are gaining more and more attention in corrosion-resistant applications and also in the transport and automotive industry. The outstanding mechanical and corrosion properties of DSSs highly depends on the austenite-to-ferrite phase balance (A /F). This phase ratio can shift in a large scale during welding. Thus, the heat input and the shielding gas composition should be optimized. Nitrogen addition to argon shielding is frequently used in DSS welding, because it is a potent austenite former. The dissolved nitrogen content in the heat-a ff ected zone and the weld metal (WM) predetermines the A /F. To determine the e ff ect of heat input and nitrogen content in shielding gas, two di ff erent heat inputs and six di ff erent gas compositions were used in autogenous tungsten inert gas welding. An improved theoretical model was established in order to simulate theWMdissolved nitrogen content, which calculates it with less error than the initial models. The correlation between nitrogen content and arc voltage was also determined. This improved model delivers the basics for shielding gas selection and the subsequent weld design for optimal A /F for industrial applications.
