The weld ____ is the point where the weld bead contacts the base metal surface.

• A. Toe
• B. Root
• C. Face
• D. Edge

Answer: (A)

Weld bead anatomy includes the face, the root, and the points where the bead meets the base metal along its sides. The point where the weld bead contacts the base metal surface along those sides is called the toe. It marks where the bead transitions from the main body of metal into the base metal as it spreads out along the joint. The root is the bottom part where the weld enters the joint, and the face is the top surface of the weld. The term edge isn’t used to describe this contact point in standard terminology. In fillet welds, you’ll have two toes, one on each side, which is important for understanding how the weld blends with the base metal and how stresses are distributed.
