Welding ads additional stresses to a crank. I've only seen one crank that had the journals built up in an aircraft engine (150 Franklin). It was cracked through #5 journal when I tore the engine down at 30 hours SMOH. No more than a Corvair crank costs, buy another crank. I expect William Wynn would tell you the same. I would rather use a .020 under crank than one that was built back up to standard.
