Boeing SLS Dome Friction-Stir Welding at NASA Michoud

Friction Stir Dome Assembly at NASA Michoud
At NASA’s Michoud Assembly Facility in New Orleans, Louisiana, a large aluminum dome section for the Space Launch System (SLS) undergoes friction-stir welding. This advanced technique, performed by a PAR Systems I-Stir Friction Welder, joins thick aerospace materials by using frictional heat and mechanical pressure to create strong, defect-free joints without melting the metal. Boeing engineers utilize this precision process for critical rocket and space vehicle components, supporting the Artemis program's deep space exploration missions. The Michoud facility has a long history of large-scale fabrication for space programs, including the Saturn V and Space Shuttle, continuing its legacy as a vital center for American spaceflight infrastructure.
