Welding a gauge in a flame hardened cast iron machine base way?
(OP)
I have a large G&L boring bar saddle with a score in the 55Rc hardened machine way. I am grinding the machine base but to clean up the gauge, I would have to take between .020 to .030 off the entire way structure of this machine. This boring bar saddle is quite large. The gauge is approximately 12 inches long .030 deep and .13 wide. Any ideas on how to patch the defect so the grinding can be just a clean up grind. Can I TIG weld the gauge before grinding and if so are there any recautions or procedures that I have to give the weld shop? Open to other ideas.

Have you checked the entire bed/ways for straightness? Do you know the cause of the gouge in the first place, there could be other issues.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
