Welding NI99 rod with Thermal Arc Fabricator 181i
Posted: Wed Feb 03, 2016 12:44 pm
Has anyone welded cast iron with NI-99 / NI-55 rods using a Thermal Arc Fabricator 181i? If so, what kind of experience did you have? Any suggestions on running these rods with this machine?
Several of us are restoring a cast iron anvil from the 1870's and we may have to weld using this machine. There will be several layers of weld metal. The anvil must be pre-heated to 450 deg. prior to welding. After this a butter layer of NI-99 / NI-55, then multiple layers of Stoody 2110 and finally up to 3 layers of Stoody 1105. Each layer must be peined (peened) and then the anvil normalized over night in a heat blanket, sand, vermiculite, etc. Then after all this, the top must be ground using a cup stone. That's a lot of grinding.
