Why would welding another nut on be any different? if it didn't break free the first time why would it with a welded on nut? To me it would only work if the studs have been removed prior and the threads chased,and,had never seize or something on the threads making the stud unscrew easy with no bind on the threads.

The key to the process is the heat cycles of the material. The expansion and contraction of the stud when heated is what breaks it loose.
