state ofmaterial properties employed in a numerical welding simulation,having a direct in-fluence on the developing stress state.Three different CCT diagrams for S355J2 steelwere employed to understand the influence of variations in CCT behavior on the nu-merical calculation of welding-induced residual stresses.The CCT diagrams wereconstructed from transformation data contained in the Sysweld software database,measured dilatometric data from Gleeble experiments,and transformation data cal-culated from the JMatPro software.The calculated transverse and longitudinal resid-ual stress distributions provided a qualitative correlation only in comparison to ex-perimental measurements,with the largest deviation occurring near the weldinterface.Overall,the results indicate a weak dependency of the calculated residualstresses due to anticipated CCT variations.The most significant effect on the calcu-lated residual stresses was shown to be related to the proportion of formed marten-site.It is suggested that CCT data of approximate accuracy is sufficient for reliablecalculation of welding-induced residual stresses.  \nmote brittle fracture,fatigue failure,andstress corrosion cracking(Ref.3).  \n## Introduction\n\nDuring welding,residual stresses aredeveloped due to the local plastic defor-mations created by the steep thermal gra-dient that occurs in the weld zone from lo-calized heating and cooling(Ref.1).Phasetransformation strains,which are createdfrom differences in crystal structure andmechanical properties,also contribute tothe evolution of residual stresses duringwelding (Ref.2).Both the diffusive anddisplacive phase transformation mecha-nisms are often accompanied by substan-tial strains,which greatly exceed elasticstrain values(Ref.1).Residual tensilestresses result in unwanted deformationsof the welded component,increase thesusceptibility to hydrogen-induced coldcracking,and also combine with tensilestresses experienced during service topro-  \nAn historical account of research re-lating to weld residual stresses and dis-tortions is provided by Dong(Ref.4).One of the initial studies to use the finiteelement (FE)method to study welding-induced residual stresses dates back toUeda et al.in 1977(Ref.5).In recentyears,the on-cooling phase
