The first-of-its-kind GMAW procedure has passed mechanical testing and now awaits further lab results prior to earning official Navy approval. Ultimately, the Phoenix International procedures must pass three hyperbaric aluminum-weld tests: 5083 alloy welded to itself; 5083 alloy welded to a 6000-series alloy; and a 6000-series alloy welded to another 6000-series. The process and procedures have been carefully selected for easy repeatability anywhere in the world.
Lincoln Electric has worked closely with Phoenix International throughout the project, supplying a Power Wave® S350 welder and Power Feed® 25M wire feeder, as well as Lincoln Electric SuperGlaze® 5556 3/64-in. diameter wire. The Power Wave welder and Power Feed feeder are located above the surface of the water on land, connected to a push-pull welding gun with 50-foot gun cable located 24 feet underwater in the hyperbaric chamber.
