I need to add a bit of mat'l to the area around the gib screw contact grooves on my van norman mill
I was wondering if anyone has done this and if so what type of filler rod (TIG) was used?
Thank you!!

I'm not totally clear on where on your mill you are trying to add material. It's my understanding that gibs are used to make up for normal wear-and-tear. But you are talking about "gib screw contact groove" on which piece is this groove?

Pix if possible.

Since you know TIG, you also know that using Ni rod will make future machining of a cast iron part nearly impossible.

Also, TIG welding cast iron gets funky. Because the air has not been forged out of cast iron, the base metal looses lots of volume when you start to build a puddle.

I successfully TIG welded a cast iron part. Before I realized that it wasn't a steel forging. I used the regular mild steel rod.

The part is still in service and I can check the rod package tonight.

You don't use ni rod for cast iron if you want to machine it you use 99% nickle and it machines real nice. Cast it not hard to ark weld if you now how.

Just to be pedantic, but was your spell checker on Noah's crew? I like arc welding. The Ark was used to save humanity and all known animals.

And yes, welding cast iron is not that tough if you pre-heat, work carefully, peen the weld and very slowly cool the part.
