The main idea of this paper is to compare the results of FE analysis and data obtained by experiment for identification of residual stresses in welded high-strength steels. The DOMEX steels welded by two technologies are compared – steel welded with laser beam and steel welded by electric arc. Residual stresses at the surface and just below the surface were evaluated using X-rays at predefined points. These data were subsequently processed in MATLAB and evaluated. FE analyzes were performed in software SYSWELD and ADINA.
