The increasing size of modern supertankers has created a need for improved methods for the manufacture of large cast and forged ship parts, because the dimensions involved make large castings or forging blocks necessary. A recent example of this was the production of a rudderstock for a new 330,000 dwt tanker in a Scandinavian shipyard. Since the shape and size of this piece dictated the use of specialized machining tools and because the weight of the material would increase machining costs considerably, the yard investigated a different manufacturing route. This consisted of casting and forging the rudderstock in two pieces, machining one of the pieces, then welding them together. The use of the consumable guide electroslag welding process in this operation is detailed.
