Aluminum Steel Construction in a New 36M (120 Ft) Patrol Boat

Abstract

Construction of the U.S. Coast Guard Cutter Leopold, the lead ship of the 36m (120ft) Heritage Class, is discussed. A new Structural Critical Aluminum-Steel Transition (SCAST) product, Duratemp II, was selected for the welding transitions between the aluminum deck house and steel deck. The explosion bonded material's higher strength and toughness permitted use of lighter, narrower transition joints (1cm (0.375in) wide x 2cm (0.75in) thick) than are permissible with traditional materials. The unique heat resistance of the material permitted cutting and welding of the small section joints without overheating. The need for corner butt joints was reduced due to the product's reliable bendability. Welding procedures and Quality Assurance procedures are discussed in detail.
