Futuramic Gore Weld Tool

At NASA’s Michoud Assembly Facility in New Orleans, Louisiana, Boeing engineers operate a PAR Systems I-STIR Friction-Stir Welder. This specialized equipment is used to join massive aluminum dome sections, which are critical components for next-generation aerospace vehicles such as the Space Launch System (SLS) for the Artemis program. The friction-stir welding process forges metal under intense pressure and heat without melting it, producing welds with exceptional structural integrity for rocket fuel tanks and spacecraft pressure vessels. Michoud has a significant history in spaceflight hardware production, having previously manufactured components for the Saturn V rockets and Space Shuttle external tanks. The facility continues its role as a key national center for large-scale precision manufacturing and assembly of spaceflight hardware, supporting ongoing deep space exploration.
