Using finite analysis element software, the transient displacement field of automatic submerged arc welding is established. It was also considered that the thermal physical properties changes were depended on the temperature and the heat loss on the surface. At the same time, it analyzed the influence of the deformation and stress, which generated in the plate butt-welding process, to the superstructure steel welding deformation. The result showed that the deformation and stress generated in the steel plate butt-welding process are considered to be the main factors to influence the welding deformation of superstructure steel. It found the effective ways to reduce the welding deformation of the hull superstructure steel is to relieve the butt-welding deformation and release butt-welding stress before welding the hull superstructure steel.
