PURPOSE:To contrive reduction of the material for welding and shortening of the process by jointing a plate by one side V welding by forming the groove in a small V shape with gentle slope on the butt part of the thick plate for ship. CONSTITUTION:The work 4 reducing the thickness is made by providing a gentle slope on the butt side of thick plates 1, 2 in the upper deck weld zone, ship bottom outer plate weld zone, etc., of a hull. A weld zone 3 is formed by performing a one side V-shaped welding by abutting the thick plates 1, 2 subjected to the bevelling 5. With this plate joint welding method, the calories in the weld zone is reduced and the quality control for deflection, etc., is facilitated.
