SHIPBOARD ALUMINUM/STEEL WELDED TRANSITION JOINTS EVALUATIONS AND IMPROVEMENTS

To bond aluminum superstructures to steel hulls, aluminum and steel are explosion-welded to each other, producing a transition joint that is occasionally vulnerable to separation. A long-term study was undertaken to determine the causes of the bond separation and the possible solutions to this problem. The study reviewed current transition joint procedures, test requirements and bond strengths. Separation prevention measures and alternate joint materials were also considered. During the course of the study, a new trimetallic aluminum-to-steel transition joint was introduced and certified. The trimetallic design provides higher strength and higher resistance to degradation during installation, while offering potentially lower overall costs.
