I think one of the problems is that each welding job on cast iron needs to be thought about and evaluated. In some cases the contraction of the weld material will not cause a problem. And example is when you are welding two pieces together. In other cases the contraction will put stress on the cast iron. Like welding a spoke that broke on a spoked gear.

I'm curious about whether there is a good non-destructive way to
measure the post-weld stress. I recall something about an exotic lab
technique, which I read about years ago, but maybe there is something
newer.

Anyway, I have to talk to the people at Lincoln pretty soon, so I'll
see if I can remember to ask about these things.
