What is the amount of metal deposited on the back side of a welded joint called?

Explanation:
Reinforcement is extra weld metal that builds up beyond the intended surface. On the back side of a welded joint, the metal that extends past the root is called root reinforcement. The root face is a groove-weld dimension, not the amount of metal on the back side, while the cap is the final top surface of the weld, and the weld bead is the deposited metal in the weld overall. So the metal on the back side is described as root reinforcement.
