That is not realistic in this hobby, nor if you maintain your own vehicles and live East of the Manitoba border.

I found that when trying to weld through the nut, you just didn't manage to get the contact area, and had to repeat the process a couple times.

Important as well is that you don't clean the metal around the broken stud, otherwise you could end up welding the stud to the surrounding metal. If so, grind it all flush and revert to the proper size washer.

I consider every extraction a victory, and it seems like the welded assembly stay on the workbench for considerable time.

Some climb mountains, some lead countries....I extract bolts.
