Forging steel inside a zero oxygen environment Intro: I have watched one too many blacksmithing videos and now I have a question: is it possible to forge steel (either just reshape or "forge-weld") inside a no-oxygen environment?

Scenario: considering the amount of material that turns into iron oxide during the forging process, would it be possible (or plausible) to fill a room with some non reactive noble gas (maybe helium or neon) and proceed to forge inside this room? Or would it be possible to forge in a complete vacuum?

If any of these two options are possible, what are the hindrances and requirements? 

Extra info: I am not from the chemistry area and I haven't  studied chemistry in years. I took a look at some old textbooks of mine and also did some research on on Google but did not find anything specific to this question. This is purely out of curiosity, and since I don't know how reddit works (therefore can't do a more relaxed inquiry there) , I thought it was not a bad idea to ask here.
It is possible to forge iron in a low atmosphere environment, but it isn't worth it because there are few if any benefits to doing so.

This isn't true for some other metals, though, or even for some specialist steels. In many other metals and alloys the presence of oxygen or water vapour has a very bad effect on the quality of welds. But the common way to exclude air from these systems is to use an apparatus that flows some inert gas around the spot being welded rather than to fill the room with an inert gas. Some examples are given here.

This is mainly worth doing for many specialist aluminium, copper and titanium alloys where the metals are oxidised more easily than typical irons or steels and effect of impurities in the welds is much larger. It isn't as simple as just having an inert gas blanket though, as this brochure for commonly used gas mixtures shows.
