How can you build large, durable structures in deep space in a way that minimizes parts handling, simplifies construction steps, and can be automated or controlled remotely?

In a project funded by NASA, EWI and BOND Technologies have developed and validated a process based on Refill Friction Stir Spot Welding (RFSSW) to build a solar panel tower on the moon. The work involved in this program is described in Refill Friction Stir Spot Welding Enables Lunar Tower Construction, written by EWI Principal Engineer Michael Eff.

The aerospace industry is renowned for its relentless pursuit of innovation and excellence. Traditional methods like resistance spot welding and riveting have served the industry well, but RFSSW is rightfully gaining attention. Invented at Helmholtz-Zentrum Geesthacht in Germany, this method promises numerous benefits for aerospace applications.

Bond is thrilled to be a part of this project utilizing RFSSW’s capabilities to move lunar exploration forward. The team at Bond remains ever-committed to pushing the envelope of what friction welding and processing technologies are capable of – how they can be applied, and what new materials can be forged.
