This study evaluates the stressed state of the ship's hull during its welding of separate water descent parts. Separate descent of ship hull is applicable for small and medium sized ship yards (SME), where shipbuilding facilities have restrictions on length and lifting capacity. In the paper different scenarios are developed for verification. It is assumed that separately launched sections of the ship's hull are free of heels and trim, i.e., pre-ballasted, and any initial deformation in connected structures has been eliminated during the stage of hull assembly. In different scenarios, there are varying factors directly related to the strength of the ship, its construction materials, as well as those that have an impact on the production processes. Two of most used welding methods in ship building are analyzed- submerged arc welding and gas metal arc welding. The analysis shows that the stressed state of the ship's hull closely depends on the initial tense state, thickness of plate elements and welding method.
