Final Answer:
In a single V-groove weld, the sloped surfaces on which the weld metal is applied are called the groove faces.
Step-by-step explanation:
A V-groove weld is a type of weld joint where two pieces of metal are joined at an angle, typically in a V-shape. In this configuration, the sloped surfaces on either side of the joint are referred to as the groove faces. The V-groove provides space for the weld metal to be deposited, creating a strong and effective joint between the two pieces of metal. It is a common weld joint design used in various applications, including structural welding.
The groove faces play a crucial role in ensuring proper penetration and fusion of the weld metal into the joint, contributing to the overall strength and integrity of the weld.
