Spot weld cutters

Eastwood sells good ones. I prefer the type without the pilot bit. I don't like the ones that look like a tiny hole saw. Get the kind that is 1 solid bit & is the width of your spot weld. It should have the correct taper on it so the tool doesn't walk when you use it. Center pinch the weld 1st & they work great. Drill only to the depth of the top layer of sheet metal & use a seam buster to separate the panels.
