SLS LH2 tank.
They use a robotic welder that friction stir welds the panels together.
They actually invented a new type of friction-stir welding for this, which is why they didn't realize a small change in the welding pin design back in 2017 would screw up the tanks. They ended up having to build new replacements with the old pin, which caused about a year's delay for the first core stage.
