Anyone here whoi welds aluminum fuel tanks. Ev er had 1 100% sealed after first weld? mTwo id so Hats off to you and what kind of maching? Not that machiune is issue rather the user is.

Welded tank for car this weekend. One needed more fuel,once tuned out and leaned down maybe not so much. Plus extra weight ion a fed's nose never really bad thing. 5.5 feet of weld and 4 leaks. Minor but PIA, Hell two of them took about as long to get to seal as rest of damn weld did, Ended up grinding clean and welding back over them.

Yes. Mine was 100% sealed the first time. It’s the only aluminum cell I’ve ever built. Miller Dynasty.

Greart jib all I can say. Built probably dozen and ionlt remember two totally sealed first weld. Have down few harley steel tanks and never gotten perfect seal on pass but then normally something like split tank into 3 pieces, addtwo between tham and extended the whole deal workkng around multi contour angle ans ome crap like 4 all around seams and 6 or 8 oirhrs for extentions.

Wonder why they say welding is bad for eyes.LOL
