Root face is another name for which weld feature?

Explanation:
Focus on groove weld geometry. The root face is the small flat surface, or land, at the root of the groove. It sits along the bottom of the prepared notch where the two pieces meet and provides the seating surface for the weld root, helping control penetration and alignment. This feature is part of the groove setup but is not the bevel angle itself, not the overall groove opening, and not a fillet weld, which forms in a corner rather than in a groove. So the term root face describes that specific flat area at the root of the groove, which is why it’s the correct concept here.
