tack welding vs full bead

SS to mild steel

No, not a no-no. Care has to be taken to avoid ruining the anti-oxidation features of the SS near the weld, and the weld itself will definitely oxidize if left bare. But structurally, welding SS to mild steel will work fine.

Matt can tell us the right wire to use (by alloy), etc. Me, I'd use tri-mix and ss wire to give the best possible oxidation resistance at and near the weld.
