if the keyway isn't too roached adding a second key was an approach that many used back in the day.
i never liked the idea myself.
welding a crank can destroy it but steves method if done carefully can work.
the idea is to heat locally in a tiny section.
if you just tap and leave the area heated shouldn't effect the metalurgy of the whole crank just the immediate area.
this still would be a negative if you reground a keyway as the metal there isn't tempered anymore.
personally i wonder why you'd weld at all if you're excluding the key unless there's ALOT of material missing.
if steve w could please elaborate i'd be grateful!!
