And more cast iron mig welding.

[aametalmaster]

I have been looking for odd cast iron parts to try this mig wire out on and my neighbor brought this old Ford tractor exhaust manifold over. It had a gasket leak and was wore pretty bad on the end. I ground it to shiney metal and put the wire to a test. 1 minute later i was done. No preheat just ran a simple bead for him to file flat. I used argon gas with the wire. I didn't get a pic of the finished part but he filed it flat and installed it back on the tractor and it worked perfect...Bob

Looks real good. I don't have any cast to fix yet but its nice to know that there's some good wire out there to get the job done. It looks like it lays a real nice bead too.

Just curious Bob, on your first post you talked about pre-heating but you chose not to on the manifold. Was there a reason for not doing so? This looks like a good way to weld cast-iron.

Thanks

I couldn't see heating it since it just was a cosmetic fix and not a crack. Plus it was pretty thin and heated right up when i started welding on it...Bob
