Yes, you would wrap the sheet to form the overall tank shape, weld in
a baffle or three working from the open ends and then weld on the ends
to close things up.

'Kay. makes sense. Al I have to do now is learn to weld aluminum!

Or, you can drill holes in the outer skin where the baffle flanges are
located and then weld them from the outside. It's a lot easier than trying
to get a stinger in the tank.

Learn how to weld Aluminum? After a couple thousand in dedicated equipment,
and a hundred hours of practice, you'll certainly be qualified. It's a
little easier than turning crankshafts, I suppose. If it was me, I'd spend
my time doing fun things and leave the 20 minutes of welding to the pros.
