I don't have any experience on that, but my opinion:

It can be welded, no doubt about it.
But the condition of the wheel after welding is the concern.
It could be distorted, etc. But if it passes all those post welding inspections, it should be good to go (but may need some cosmetic work, ie grind/polish etc). I don't know about the heat treatment in the weld effected area (ie aluminum 6061, 50xx, 70xx, etc.)
