I was wondering... with aluminum tire rims are they at all practical to weld? I understand the liability involved and would NEVER take on a something like that. I was just curious if it was possible or practical to do, say come the end of civilization and you have no choice but to weld an aluminum wheel to move your stuff or have it stolen by Road Warrior types?
The ones I have looked at look like they were cast and then polished, but what do I know. Well, there are also the custom ones for motorcycles that are machined out of a solid billet of metal too, but those are not the ones I am talking about.
