Draft Policy for the Use of Electric Welding in Submarine Hull Structures
- AI summary (β)
- This item is a draft policy (circular notice?) titled “Draft Policy for the Use of Electric Welding in Submarine Hull Structures,” establishing the areas where electric welding is to be applied or prohibited in submarine hull structures. It sets out general policies to avoid special-quality steel materials, on-site welding, overhead welding, and locations subject to intense vibration or repeated impact. Transverse bulkheads, fore and aft end materials, built-up frames, interior deck beams, various “tanks,” superstructures, access trunks, “divers’ locks,” pressure-resistant storage trunks, rudders, and similar parts are, in principle, to be welded, while inner shell plating, outer shell plating, “vertical keels,” “ballast keels,” and similar parts are divided between riveting and welding according to conditions. Date and publication information are unknown. Keywords: submarine, hull structure, electric welding, riveting, inner shell plating, outer shell plating, transverse bulkhead, ballast keel, vertical keelAuto-generated by Azure OpenAI gpt-5.5 from OCR text (which may contain errors) and image captions.
