CHOOSING OPTIMUM METHODS FOR THE CUTTING OF HULL PARTS, TAKING THE TYPE AND VOLUME OF PRODUCTION INTO ACCOUNT

A concise review and analysis of the methods and equipment used for the thermal and mechanical cutting of plate in shipbuilding, including quantitative and other information on the productivity and economics of the equipment types. A number of recommendations are made as to which methods and equipment are preferable for various cutting and edge-preparation applications. These recommendations embrace plasma cutting, cutting of pairs of mirror-image plates, flame-cutting, laser cutting, mechanical cutting, and control systems for the machines, and are in broad terms (individual makes of machine are not, in general, mentioned). A final recommendation is that, where there is a steel throughput of over 30,000 tonnes/yr, three types of machines should be provided: a two-position (i.e., mirror-image) plasma-cutting machine, a single-position plasma-cutting machine, and either a three-gantry flame-cutting machine with three-torch equipment or a two-position flame-cutting machine. The number of each of these machines would depend on the production volume and conditions. The possibility of developments in plasma cutting eventually leading to its completely replacing mechanical cutting and flame-cutting is mentioned.
