Triplate Transition Joints

The vacuum-explosion welded transition joint, called TRIPLATE is a high quality material for welding aluminium to steel. TRIPLATE is most often used in shipbuilding as a transition joint, for example welding an aluminium superstructure to a steel hull.

Atmospheric vs. Vacuum Cladding

Although atmospheric cladding is an effective process there appears to be advantages if the explosive bonding process is carried out under vacuum. This produces a smoother wave bond between the aluminium and steel. The ductile aluminium steel joint helps easy sawing and forming. At the present time only one manufacturer in the world has the capability to produce explosive clad products in a vacuum and their products are distributed by Righton Marine.
