mig welding will work just fine. almost any body or repair shop has mig welding and it doesn't take a true expert to get a decent weld.
NOTE. use a nut of sufficent size then you weld on the inside of the nut. make sure of a good contact. doing it this way will also contain the welding sparks. you should apply some spatter spray or paste to catch any errant sparks that may fly.
also don't fill the hole completely that helps contain the weld and be sure your first strike for arc is on the lug nut not the added on nut. the weld to the lug nut is the important one that must be sure to take. remember your going thru chrome so if you don't take it off that has to be burnt off first for the wire to stick to the lug. so you may want to slight grind the surface off of the lug nut
