This paper presents a study on the elastic behavior of welded pressure equipment (PE) assemblies, incorporating the weld imperfection quality levels specified in the ISO 5817 standard. The objective is to develop a finite element model of this structure and analyze the maximum stress in fusion-welded plate assemblies. First, welding fundamentals are defined; second, pressure equipment is introduced; third, details of the ISO 5817 standard are outlined. Fourth, welded joints under static loading are modeled using ABAQUS software to determine maximum stresses at their transverse cross-sections. Finally, a comparative study evaluates the performance of quality levels relative to Level B.
