That's exactly why large pressure tanks are rounded.
I had the same crack in my tank. I took it to a local welder who does a lot of aluminum work. He said the biggest problem is cleaning the surface of the antifreeze contamination. So far his work is holding after two years.

IMHO, it's a "quality control" issue. I had one tank re-welded and the resulting bead was significantly thicker than the original bead. Mine tanks were not the original tanks in the car, but a completely new tank.
Bob D.; I got my some of the original wet application epoxy from Bob Hall so I don't recall the brand, off-hand. I believe what I have now is actually a J-B Weld product called "WetWeld". Sets very fast so I was able to use it between track sessions when I had a crack the size of the one seen in a prior post on this thread. Mine happened on the opposite side of the tank at the "L" portion of the tank.

It came in a tube and was JB Weld. You kneed it to a consistent color and apply. I don't know how long I have had the tube, but it has been awhile.

Just to be clear, my tank crack was not a quality control issue. I got airborne enough that when the car came down, the rear body section slapped down on the tank. Even the bracket was bent down. A good friend welded it up like new for a six pack of beer. All's good.

I just found JB Wet Weld at my local tractor supply.
