Quote: grinding a weld smooth will yield a ~2x improvement in fatigue life in steel
This is an amazing tidbit of information. You'd think NHRA, NASCAR and the aircraft industry would be insisting that all welds be ground smooth!
very costly, usually a last resort kind of thing to get the desired fatigue life....they do analysis to determine if they need to or not.
