Leaks happen in clean-room environments, with excellent back purge, and cameras inside the tanks, as I learned from the guys who build Kenworth and Peterbilt tanks. Perfect appearing TIG welds, inside and out - leak - because of weld density issues. Welds are sliced open along their lengths, and voila! - porosity inside the weld, invisible from outside.

It's a problem that the most expensive tig machines are only just now starting to overcome.
