Abstract: A rolling stock fitting structure has laminated panels, each formed by sandwiching a core member between a pair of face plates, and channel members are placed between the face plates around the periphery of the panels and possibly in the interior thereof to provide structural strength. The laminated panels, which may be shaped to conform to a particular design, are joined and welded together to form a rolling stock body. The channels are provided with holding members for holding equipment, so that the load of the equipment on the holding member can be distributed through the channel member to the laminated panel, thereby securing the equipment reliably.

Abstract: A rolling stock fitting structure has laminated panels, each formed by sandwiching a core member between a pair of face plates, and framing shapes are placed between the face plates around the periphery of the panels and possibly in the interior thereof to provide structural strength. The laminated panels, which may be shaped to conform to a particular design, are joined and welded together to form a rolling stock body. The framing shapes are provided with a support shape for holding equipment, the support shape being mounted on a rod fixed to the framing shape, so that the load of the equipment on the holding member can be distributed through the framing shapes to the laminated panel, thereby securing the equipment reliably.

Abstract: When a welded joint is produced for joining metal components by applying a plurality of layers of deposited metal, the plurality of layers of deposited metal are provided in a groove of a weld preparation formed between the metal components to be joined in such a manner that each layer of deposited metal has a small thickness and a large width crosswise of the groove and the layers are arranged to be superposed one over another. During this process, a coarse metal structure formed when each underlying layer of deposited metal is provided is completely tempered and transformed into a fine metal structure by the heat generated when each overlying layer of deposited metal is provided. Thus the welded joint produced by this method shows an excellent performance in service.
