For pressure hulls of Deep Submergence Vehicle (DSV) operating in seas of 2000 m depth, the most important point is the maximum load carrying capacity under the minimum weight. For this reason, spherical shell made of high strength steel is adopted for pressure hulls. The heattreatment conditions and GTAW welding conditions of HT 100 steel have been investigated in report 1. In this report, a procedure of decision of welding condition for high strength steel like HT 100 is proposed. And using this procedure the full scale model of spherical pressure hull was fabricated. After completion of this model, the weld metal was proved to satisfy the requirements of the destructive and non-destructive tests. (Wassmann)
