V
Describe a V-Groove
The 2 surfaces are machined flat and smooth at an angle (bevel). When the 2 surfaces are placed together, they form a single “V” shape. In some cases, the root of the “V” does not extend to the bottom surface of the material.
Describe a Double V-Groove
The edges are beveled from both sides. When placed together, the 2 pieces form a “V” on both sides. Both sides are then welded.
