Opinions on the Policy for Applying Electric Welding to Submarines, 11-2-4, Lieutenant Commander Nakamura, Shipbuilding
- AI summary (β)
- An opinion paper dated February 4, 1936, by Lieutenant Commander Nakamura, Shipbuilding, discussing the policy for applying electric welding to submarine hull structures. It considers the securing of watertightness and oiltightness and weight reduction as advantages, and examines disadvantages such as internal stress and sagging moment, and reduced pressure-resistant strength due to distortion of the inner hull. It refers to the I-56 class, I-61 class, Ro-33 class, I-74 class, Kaidai VI class, experiments at Kure, and investigations by Staff Members Matsumoto and Maruishi, and sets out as its main points restrictions on use for the inner hull itself, the attachment of large structures, on-site welding of the outer hull, and forward and after outer plating. Keywords: submarine, electric welding, Lieutenant Commander Nakamura, Shipbuilding, inner hull, pressure-resistant strength, sagging, Ro-33 class, Kure experimentsAuto-generated by Azure OpenAI gpt-5.5 from OCR text (which may contain errors) and image captions.
