Right Answer is: B
SOLUTION
Nomenclature of butt and fillet weld:
Root: The parts to be joined that are nearest together
Root gap: It is the distance between the parts to be joined.
Root face: The surface formed by squaring off the root edge of the fusion face to avoid a sharp edge at the root.
Reinforcement: Metal deposited on the surface of the parent metal or the excess metal over the line joining the two toes.
The toe of weld: The point where the weld face joins the parent metal.
Weld face: The surface of a weld seen from the side from which the weld was made
Root penetration: It is the projection of the root run at the bottom of the joint.
Throat thickness: The distance between the junction of metals and the midpoint on the line joining the two toes.
Leg length: The distance between the junction of the metals and the point where the weld metal touches the base metal ‘toe’.
The length of the leg is the distance from the root of the weld to the toe of the weld.
The theoretical throat is the perpendicular distance between the root of the weld and the hypotenuse joining the two ends of the length. It is the shortest distance from the root to the face.
