I would strike the plug several times really hard on the face with a heavy
hammer to help loosen it and use a tight fitting six-point impact socket
with a strong and long pull handle. Grind the face of the socket if needed
to remove the bevel. Dress the hex on the plug if needed for a good fit.
Then press the socket tightly in place and pull. You will either remove the
plug or the center hex will twist off. I don't think welding on a nut would
be any stronger than the hex itself.

An addition to what Don suggested would be to use a breaker bar with a small
hydraulic jack under it to keep the socket from camming off as you apply
torque to fastener.
