Solid-State Welding Processes Being Developed for NASA Manufacturing Programs Could Significantly Reduce Workboat Fabrication CostsWhether it is for a tug boat, cargo vessel, or an offshore supply ship, much of the workboat fabrication industry is located along the Southern Coast of the U.S. But a visit to any one of the workboat facilities in that area (or any other in the country) would reveal antiquated and archaic fabrication processes used seventy years ago. The workboat manufacturing process is very expensive, labor intensive, and has not really changed since World War II.
