Sounds nice. If it is a ornate wood burning stove, I would expect it
was cast iron.

and...

If it is cast iron, what did you use for arc welding electrodes?

Some stuff that's been waiting in a can for 25 years.

I knew someone in Washington State that embedded a mail box in the
front half of a junk car. The mail box was not real obvious so it
looked like a car coming out of a thicket of blackberries.

Nice evasion . I TIG CI with either strips of CI cut from an old
woodburning stove door or with Invar 42 (thanks Dan!) or braze with brass .
I haven't used any but understand there are a couple of nickel based
electrodes that work well .
So tell us , did you preheat ? Cool slowly after welding or peen the welds
as they cooled ? Weld it cold and pray ?
