Yeah, you are right. Sometimes I know I get carried away with the theory (I'm an engineer) and I don't necessarily have a good understanding of what is actually ok. I deal with aircraft parts, where something like this would definitely not be acceptable and would most likely cause fatigue failure.
However, in talking with several experienced people, especially other machine shops that do crankshaft welding, I think this won't be a problem. Apparently, some weld pitting is very common and acceptable, and most shops do not pre-heat or post-heat the crankshafts.
Anyway, thanks for the response!
