So I'm sitting around dreaming of flying my plane someday and contemplating my stub wing tanks.? The outer wing tanks are welded aluminum and that was fine but a bit pricey.? My mains are .032 aluminum sheet and I got to thinking how hard it was going to be to weld such thin sheet.? Poking around the internet I found that in fact you can spot weld thin aluminum sheet (see video) and as luck would have it I have a new 220V spot welder sitting on the shelf.? My plan is to use this technique to spot weld my tanks together and seal the seams with Pro-Seal.? Anyone heard of spot welding fuel tanks or aircraft skins?
