Was looking for a recommendation rather than some random link on Google, which I could find myself.
I have bought steel from Dundas in Winchester and had them bend a axle back into shape. A buddy of mine has had some welding done by them. They also sold me some mig parts at less then the dealer.

Out of curiosity.... what do you need welded? In a lot of applications, cast iron welding is a relatively short term repair.
Cast Iron should be brazed and not welded
Parts for an old 1940s woodstove. Why do you say it can be a short term repair?Quote:

Obviously it's better than scrapping something irreplaceable, I was only curious if it would be a worthwhile cost vs longevity if it was something able to be purchased.
If it's a leg or an ornamental part it will probably be fine, brazing is usually better for sealing or repairing cracks because it is far more ductile than the casting so it won't Crack like weld.
Is it a small part. Preheat is easiest. Small part could be prepped and put in a wood stove bring it out weld it then returned to the stove coals. To cool slow
Braze or arc weld it it’ll likely fail again if it could be pinned success would be better
Ain’t Gona be cheap you could have beautiful repair and thats peaned out and it rebreak or luck may be on your side.
But stove if it can’t be pinned failure could be stove falling over?
