摘要：
The torsion box structure of a container ship is usually fabricated with 60-85 mm-thick high-tensile-strength steel plates. The complex multipass welding makes the welding mechanical response extremely complicated. In addition, it is difficult to predict the out-of-plane welding distortion, which directly affects the construction precision and shipbuilding cycle. To solve the issue of fabrication accuracy, the thermal-elastic-plastic finite element (FE) analysis is applied on the basis of parallel computation, considering the re-melt phenomenon. The out-of-plane welding distortion of a variable-thickness butt joint welded using the traditional welding procedure is effectively and precisely predicted. Furthermore, sequential welding procedure, reverse deformation loading and, especially, the welding groove design optimization method, were used to effectively control the out-of-plane welding distortion. In particular, the groove design optimization method could achieve efficient and accurate fabrication for a thick plate with one turnover. © 2019, Editorial Department of Journal of HEU.
