I hesitate to disagree with Rusty who knows his stuff, but I don't think that a good weld job on a cast iron part subject to considerable thermal expansion and contraction is "a simple job". I've seen it done a number of times by a shop that specializes in this work; the just the gradual heating up in a furnace, welding while HOT, and then the controlled cooling over a period of days is anything but simple. Maybe there are other methods that I'm not familiar with.
