In this paper, the influence of weld corrosion on the mechanical behavior of a welded joint pipeline was investigated using corrosion and mechanical simulations simultaneously. In the corrosion simulation, the modeling results (i.e., the corrosion potential and current density) revealed that the welded joint is preferentially corroded and the corrosion rate is higher in the outside environment due to the severe corrosion factors. The increase in corrosion degradation according to the operation time increases the stress concentration on the welded joint, indicating that the failure risk of the welded joint is increased with increasing corrosion degradation. These results can be used to evaluate the lifetime of welded joints exposed to corrosion and suggest guidelines for the maintenance of structures.
