I bought an old andiron. Goes in front of a fireplace as somewhat of a screen. Made of cast iron. Breaks are clean. I would like to weld this back together, but strictly for decorative. It will see no heat. I will bead blast it, or just wire wheel it.
When I did ornamental metal, I welded on thousands of those cast iron picket points with E 70S-3 and 6 wire with CO2. Right now, I have 75/25 mix. The metal is only about 1/4" thick, so not sure if I do groove it if there will be enough meat there to not burn it up.
I am thinking of just cleaning it, and welding it with MIG, and calling it good. I know it's not the proper repair for cast iron, but for decorations, it should be good to go? No? Is there nickel MIG wire I can get in one pound spools? Preheat?
