The U.S. Navy has been searching for new weld-repair methods on its aluminum-hulled ships beyond dry docking, which is impractical and costly. Phoenix Intl., an underwater services company that has held the Navy’s Diving Services contract for the past 15 years, may have found one: underwater aluminum GMAW in a hyperbaric chamber.

Submerged arc welding is known as a process that can result in high welding speeds and deposition rates. However, in today's manufacturing reality, engineers are always looking to boost productivity—even for already productive processes. Fortunately, companies have three common approaches to consider to increase the performance of their submerged arc welding systems.
Chronic exposure to manganese oxide fumes, which occur when manganese metal is heated and reacts with oxygen, can lead to damage to the central nervous system. Welders are especially susceptible to this disease, called maganism by the National Institutes of Health, because manganese is found in many welding rods and filler metals to promote hardness. The American Conference of Governmental Industrial Hygienists recently issued guidance that dramatically reduced suggested threshold limit values. Because many metal fabricators use this guidance to manage worker exposure, they now are having to rethink how they approach personal protective equipment.

A shop is only as productive as its constraint process—that is, its bottleneck. All that adaptability in upstream processes may not make a part cost less if it takes days or weeks to build a new weld fixture. A modular approach to weld fixturing can help.
