Recommendations

Place a nut of appropriate size over the hole with the broken bolt.

Weld through the nut, holding the electrode parallel to the axis of the broken part, without interrupting the arc until the threaded hole is filled and a “cap” can be formed.

After cooling, unscrew the welded nut together with the broken part.
