ABSTRACT:
A method for manufacturing a large basically spherical vessel from plane aluminum plates having a thickness in the range from about 20 mm to about 70 mm, comprises (a) forming at least first and second plane plate assemblies by downhand welding together plane plates controlled by a welding device including an adjustably lockable portal, (b) cutting each welded plane plate assembly to a peripheral shape that fits into the structural pattern of the vessel except for an allowance for machining in step (d), (c) bending each plate assembly to part-spherical configuration, (d) machining respective edges of the first and second bent plate assemblies to a profile suitable for welding in step (e), and (e) downhand welding the first and second plate assemblies together along the machined edges using a manipulator device that includes a tiltable support.
