Not a metalurgist, but agree the oxide problem would go away. However I think you'd have a worse problem with heat. Aluminum in my limited experience gets really hot and soupy when welded, so that you have to go quite fast in many cases. Without an atmosphere to sync some of the heat, you might have very interesting thermal issues. You'd definitely need much bigger heat syncs. However depends likely on the scale of welding that's happening. Definitely will be interesting.
- bloggie 2y agoLaser welding has quite different challenges from electrical welding as the heat-affected zone is so much smaller, much less energy is delivered to the metal to perform the weld. I'd like to read more about the research in the article to see what they've done to address this or if it was even an issue for them! It probably depends on the thickness and orientation of the metal and fixturing.
