About the Topic: NASA’s Orion Program is currently building the crew module for the Exploration Mission-1 flight which will be an uncrewed mission around the moon. The aluminum components of the pressure vessel primary structure of the crew module portion of the vehicle are being joined together using a variation of friction stir welding (FSW) called self-reacting FSW. Self-reacting FSW and welding of the crew module will be discussed as well as some of the challenges and successes with using a new variation of FSW on critical spaceflight hardware.
About the Speaker: Dr. Lucie Johannes is the System Manager for Materials and Processes on the Orion Program at NASA. She has Bachelor of Science and Doctor of Philosophy degrees in Metallurgical Engineering from Missouri University of Science & Technology (University of Missouri – Rolla), a Master of Engineering in Materials Science and Engineering from the Massachusetts Institute of Technology, and a Master of Science in Welding Engineering from The Ohio State University. She is also a registered Professional Engineer. Dr. Johannes is a member of the AWS D17 subcommittees for fusion and friction stir welding for the aircraft and aerospace industry.
