Study of the Mechanised Manufacture and Welding of Reinforced Shell Units From Rolled Shell Plate and Tee Bar Segments
Abstract
Simple Stage by Stage Production with Step by Step Monitoring and Time Recording Control establishes a system eminently suitable for the accurate handling and positioning of a workpiece relative to the operation to be performed. A balanced distribution of the workload between Stages maintains an inbuilt flexibility throughout the complete operational sequence. In other words the end product is without restrain successively built up through selective positioning with fully balanced heat in-put control throughout a Stage by Stage Production System. Loading, unloading and transportation of components, sub-assemblies and final product is so planned as to prevent any possible damage to work already completed. This Study attempts to describe two mechanized methods of Shell Ring manufacture; both are according to a Stage by Stage Production Method. Alt. 1: Carried out without the use of Shop Crane for Shell Rings up to 34 ft. in diameter, 75 U.S. Tons in weight and 12 ft. in length. Alt. 2: Carried out with the partial use of Shop Crane for Shell Rings up to 44 ft. in diameter, 100 U.S. Tons in weight and 10 ft. in length.
