    • The invention relates to a method of painting a ship's hull section or the like. The method comprises: a sintering process, in which an electrostatic powder paint 2 is spread evenly over both sides of the steel plate 1 undergoing workshop priming or treatment for chemical reaction coating 1a after having been shot-blasted or steeped, the excess electrostatic powder paint spread on the steel plate is removed by the use of a numerically controlled suction nozzle 3, following which the electrostatic powder paint 5 spread on both sides of the steel plate is sintered by a high-frequency sintering process; an intermediate section assembly process in which the sintered steel plate 1 undergoes numerically controlled cutting 8 to the predetermined shape and related steel plate is welded 15 together with an unpainted section in order to produce an intermediate assembly section 9; a main section assembly process, in which a number of intermediate assembly sections are welded together in order to produce a main assembly section 10; and an integrated section assembly process, in which the main assembly section undergoes a second surface treatment 11 through steeping, following which a second painting 12 is performed on the main assembly section prior to the formation of an integrated section 13.
