Purpose: Investigations include finite element model FEM of the various weld test performed on lean duplex stainless steels (TIG, MIG) and study calculated heat thermal cycle and deriving parameters. Design/methodology/approach: The FEM model was also applied to evaluate residual stress on the weld surface. The accuracy of the FEM model was verified by comparing the results of the computer simulation of the stresses with experimental results. Findings: Obtained result can be correlated to measured ferrite content in the weld, thus providing a simple prediction of phase balance in weld microstructure dependent on introducing heat input. Comparative analysis of the numerical FEM calculations and residual stress measurements made by X-ray diffraction showed good correlation. Practical implications: Numerical calculations allow to quick selection of the optimal welding process parameters. Analysis of the thermal cycles curves has enabled to determine the basic parameters such as maximum temperature, heating time and cooling down and the rate of temperature is reached maximum and intermediate temperature ranges important for phase transformations. Originality/value: A computer simulation of the stresses was carried out in the ANSYS environment using the FEM method.
