Hope you used a bottoming tap .....

Not yet. Only had a standard tap, I'll pick one up and run it up and down before re-assembly.

Weld a nut on with an electric welder, let it cool and you can likely turn it out with your fingers. Know why?

The welding current goes through the bolt, through the rust to get the cylinder block where the welding ground clamp is located. The rust is high resistance to current flow so it gets real hot and turns the rust to dust. You can do the same with a battery and booster cables.
