Expansion tank aluminum welding

[Junbug]

So after our first go-cart we found the aftermarket aluminum coolant expansion tank appears to be have small crack or bad weld on the bottom of the tank. Its on the seam where the over-pressure release eyelet from the fill cap goes through the tank and comes out the bottom. I verified it wasn't coolant leaking through that eyelet, but rather forming a drip and coming through a small crack/gap in the weld. See point of arrow in pic below. I've reached out to the manufacturer to see what they plan to do. Worst case I'll need to take it to a local aluminum/fab shop and see if they can fix it.

I'm not an expert at welding or aluminum welding so I'll go with asking the pro's for advice on this. Any thoughts as I engage local aluminum/fab shops? Also added a short video of the first go-cart just because it was awesome!

I’m not quite understanding what that is but no matter, any good welding shop should be able to repair that easily.
