In shipbuilding, our Detacouple structural transition joints are the world-renowned standard for permanent, aluminum-to-steel welds — welds that connect aluminum superstructures and bulkheads to steel hulls, framing, and decks.
NobelClad's structural transition joint are approved by the American Bureau of Shipping (ABS) and the joints are made using a patented bonding process certified by Military Specification MIL-J-24445A and NobelClad Product Spec DETA-604M and NC 603.
Replacing mechanical fasteners, Detacouple structural transition joints provide strong, maintenance-free, aluminum-to-steel welds for thousands of structures aboard today’s marine vessels and offshore operations. Shipbuilders and naval architects have and continue to rely on Detacouple structural transition joints to:
Reduce vessel weight
