Tom , that information you just described, tells me that you are knowledgable about ss and monel fabrication.

There is a piece of information on welding ss , that I hope you can clarify .

I have been told that when welding ss, some of the chromium and nickle are boiled away, from the molton puddle, vaporized as it were, and that changes the alloy balance percentage to somewhat less than the mil spec ,,,,, ie 18 - 8 , might be less, of a percentage, at the finished weld.

I have been also told that using a filler rod, higher in content (richer) of chrome and nickle, likely will replace that boiled away "lost" chrome and nickle , thus keeping the alloy percentages more near the mill spec.

Is there any truth to these ideas of enrichening a weld ?
