I have always heard of the technique of hitting t he outer surface of metal with something as "peening". "peening" being usually just using a hammer, or "shot-peening" to surface condition a piece of metal. I have not heard of"peining", and cant find any reference to it on line. So I guess I do not know.....Question: is it peining or peening? One's a surface treatment. The other's a fabrication technique. I'm confused.
