No full textPerforated plates are widely used as components in heat transfer equipment, playing a vital role in the plant safety. When their fabrication includes welding, the distortions due to this process should be estimated and reduced, as much as possible. The only way to do it in the design stage is by modeling and simulation, the most suitable method being the finite element method (FEM). This paper presents a methodology for simulation of perforated plates multipass welding in order to compute residual stress and distortion, using FEM. It involves a combination of 2D and 3D analyses, thermo-elasto-plastic and elastic models, submodeling, equivalent material data and experimental work
