I am beginner in welding, and excuse to add my answer which is according to what I KNOW (it is not necessarily correct). The answer is a "yes". A carbonizing flame is also called a reducing flame.
Yes, that's it! You might read "carbonizing" or "carburizing", it's the same idea: there is excess carbon in the flame, it's chemically active and it might be touching something chemically active (like a red-hot piece of iron), not only can it "REDUCE" oxides on the surface of that metal, but carbon can actually enter that hot metal and dissolve in it- for good or for ill! Personally I suspect that when using fluxes (which are glasses, made of melted oxides) that a reducing flame makes trouble because it reduces the FLUX! This is related to some bad experiences in glassblowing. I'm shooting for neutral or slightly oxidizing flame for flux-covered metals. I guess when in doubt neutral flame is always a good guess!
Here they might not say "carburizing" because I suspect that carbon doesn't dissolve in copper and silver alloys, maybe they don't BECOME carburized, so it doesn't come up in this industry? They can definitely reduce an oxidized surface!
The reducing flame is also called carburizing correct? Is that only with OA (which is what I am learning) thanks!
