Body shops use spot weld drills to separate spot welds.  It looks like a
small hole saw, just slightly bigger than the spot weld.   To use it you
drill, theoretically, just through the top layer of metal which frees it
from the lower level.  Any body shop supply place should have them
.    .    .    or mail order from Eastwood, TIP, etc.

Hope this helps,
