Stop at a Napa store and ask for a spot weld drill bit. These are specially designed to drill the center welded part of a spot weld out.

as the same as if you are spot welding you heat the job and not the solder, the solder will melt if not it could need drilling out all depends on where it is
I once took the sills from a car the hard way a cold chisel or coal chisel a solid steel or iron tool and a large hammer belt belt blt until each spot broke apart that meant removing rubber seal and any carpet footmats and edgings fitted to the floor pan of the car and then getting the sill and the chasis open enough to slot the chisel in place to start breaking the welds andrewj

How you take it apart depends on what you want to be left with and how much speed is required.
Usually you would use an air chisel for something you wish to get apart quickly.
But when you don't wish to mess stuff up you would drill through the spot weld with a drill.

A bad one can sometimes be torn apart but it does depend on the thickness of the metal and the closeness of other welds.
If the weld is accessible you can use a circular grinder.

You could also use levers to pry a weld apart, a pry-bar, a hammer. Or you could use opposing vises to try to rip the weld apart, if you don't care about damage. Then there is always acid to eat away the weld. and files.

They make a special drill bit to drill these out. You can get them at NAPA or about any auto parts stores. You can also take an air chisel and jam it between the sheets of metal and try and seperate it that way, but it often tears the metal.

Bend it if it isn't sheet metal. A chisel or a grinder.

Hacksaw if the space permits, then file down for smooth edges
