In Episode 2 of our SME Series, Spacetron founder Rick Montoya pulls back the curtain on the hidden risks of open-air welding. Holding a titanium strike plate preserved since 2008, Rick demonstrates the undeniable difference between standard purging and the Total Immersion environment of the Tron E-24. From Hydrogen Embrittlement to the "silent failure" of cold cracks, learn why achieving 99.999% argon purity isn't just a preference, it’s a requirement for flight-critical hardware on Artemis-class missions.
