Re: welding cast iron

Easy: You braze it instead.

Seriously. Not too many scenarios where I would pick welding over brazing for cast iron. Cast steel I would weld, no probs. Cast iron? Why bother?

Re: welding cast iron

Use the cast iron rod with a stick welder. The high nickel stuff is machinable afterwards, but expensive. Welding cast iron isn't bad at all, really.

Re: welding cast iron

Wellding cast iron is a breeze if done correctly wht the correct procedure and filler.

I find vermiculite amazing for slowly cooling cast iron. http://en.wikipedia.org/wiki/Vermiculite

It is the white stuff in potting soils and can be bought by the bag at most garden centers.

Dont forget to preheat and peen!!!
