Summary

The Falcon 9 booster tank is made of aluminum lithium alloy. Welding it without forming hydrogen bubbles is tricky. SpaceX uses friction stir welding throughout. I had to crop the welding jig from the photo because of ITAR restrictions. Let me just say that it is very clever, and the challenges are like building a ship in a bottle.
