Editing Talk:Removing stuck fasteners

Welding a nut onto a broken bolt, flush with the casting or whatever tends to make for a poor weld.  As a blacksmith for 55 years, I always found it much better to weld on a clean uncoated flat washer.  Use higher welding 'heat' to expand and break down rust, etc.  Then try a large pliers or smaller pipe wrench.  Or,  weld a larger nut onto the washer, which will allow better and stronger welding.  Always let cool to room temp BEFORE attemping any removel of bolt.
