- AI summary (β)
- A document believed to be a circular notice, “On the Scope of Use of Electric Welding in the Hulls of Naval Vessels (Excluding Submarines).” Issued by the Naval Technical Department on January 20, Showa 11. Prompted by the Fourth Fleet storm accident, it points out deficiencies in hull strength, policy on the use of electric welding, and the design of applicable structures; states that, under a safety-first principle, a proposal to reduce the scope of use was adopted; and discusses reinforcement of completed vessels and vessels under construction, removal of internal stress, and improvements through future experimental research.
