Oh. I see the predicament now.

Unless you have access to an easy out and have some mad drilling skills...I'm not sure what to tell you, besides heating the hell out of that welded-on nut, breaking it off, and replacing the whole thing with a standard bolt/nut.

Most every remedy to something like this comes back to extreme heat and hammers of varous sizes.
