What is the difference between a single-V-groove and a single-bevel-groove joint?
- In a V-groove one member is beveled; in a bevel-groove both members are
- A V-groove has curved groove faces; a bevel-groove has straight faces
- In a V-groove both members are beveled; in a bevel-groove only one is
- A V-groove is welded from both sides; a bevel-groove from one side
Show the answer
C. In a V-groove both members are beveled; in a bevel-groove only one is
A V-groove is formed by beveling the edges of both members, while a bevel-groove has one prepared member against a square edge. Curved groove faces describe U- and J-grooves.

On a groove joint, what is the root face (also called the land)?
- The open gap between the members at the joint root
- The sloped surface cut on the edge of the member
- The unbeveled part of the groove face next to the root
- The backing strip placed behind the joint root
Show the answer
C. The unbeveled part of the groove face next to the root
The root face is the flat portion of the edge left square at the bottom of a bevel. The gap between the members is the root opening, and the sloped surface is the bevel (groove) face.

What is the toe of a weld?
- The deepest point of fusion into the joint root
- The exposed surface on the side welding was done
- The shortest distance from the root to the face
- The junction of the weld face and the base metal
Show the answer
D. The junction of the weld face and the base metal
The toe is the line where the weld face meets the base metal; undercut and overlap occur there. The deepest point of fusion is at the weld root, and the root-to-face distance is the throat.
