cast aluminum doesn’t weld very well at all. Sure the two pieces can be welded and it “looks” good visually…but you it’ll be very brittle and it’ll fracture at the edge, where the heat affected zone and original cast zone meet.

If it’s something that will see absolutely no stress…you’ll be fine, but if its something that has already broken it likely see stress gain.

fyi.
