I've personally heard of it being done and knew an engine builder who did
this (Larry Klein of Klein/HP Machine in San Jose). It's a last ditch
option only and for journals that aren't more than .040" off (puts you back
to 10/10 or 10/20 specs). On Ed's, I wouldn't even think about welding. Do
it right the first time, either get a new crank (or a virgin used) or, as
described below, sleeve them.

Instead of welding; why doesn't he just sleeve it. The
bearing journals can be sleeved to provide the fit you
want. And if he does this; try looking for some
stainless steel sleeves. They'll hold up better. They
do this in marine, racing and diesel applications.
You're not supposed to weld anywhere on the journals.
The original iron chemistry will be adversely
affected. Plus this could cause unnecessary wear on
any crank that you are going to put in. Let's put it
this way. My company is a cast iron foundry which
specializes in engine blocks. If we can't weld on the
journals (Cummins, Mack Truck, Detroit Diesel, Ford,
GM and DC specs says NO!); why does he think that he
can. Just a thought!
