I also have welded cast with Ni5 Ny-Rod. We start out by preheating the cast iron then lay in a bead of Ny-rod then peaning then I do just a little different by warming the welded piece up along with the preheated metal then bury it in sand up to 24 hrs. depending on how big the welded piece is with a minuminum of 4 hrs. on a small parts. This releives the stress on the metal. This is a very good way to weld up expensive vices that guys break doing stupid things with cheater bars. The trick is Slow Cooling of the Cast. Once the cast is cool you can grind it down and sand blast the part to look like the org.
