On some cars (early Alfas) the wheel studs have hex heads like a regular
bolt. These tend to round off if the lug nut gets stuck and the bolt
spins. The later ones have D-shaped heads that are less of a problem. The
bottom line is that tacking the head down with a weld or two is farly
common on some cars. Don't be afraid of it. I would swap out the loose
stud for a fresh one and tack it down as you described. They can be
ground off and re-welded as needed.
