The story of welded aluminum on ships begins with the design and construction of the SS United States. Conceived and designed by Fredric and William Gibbs as a 1000-ft express super-liner, taking advantage of the technologies that had been rapidly evolving up to and through WWII, SS United States was an avant garde vessel. The United States had, for the first time, 2000 tons of welded aluminum in her superstructure; however, the superstructure was not all aluminum. It was fully ten years later, in 1962, before another ocean liner, the SS France, was built that incorporated an aluminum superstructure (1600 tons). In conjunction with a newly reconstituted Aluminum Association, a new, nationally agreed upon four-digit aluminum alloy numbering system was developed for this ship. New application-appropriate aluminum base materials needed to be developed along with companion alloys to weld them. With a growing number of base metal combinations, research needed to be done for filler metals appropriate to many base metal combinations. Source
