Bevel-Groove Weld Symbol
A bevel-groove weld uses an angled preparation on one member while the mating member remains square. Because the preparation is asymmetric, the arrow and joint detail are essential.
- Recognize an asymmetric bevel-groove preparation
- Identify which member is prepared
- Keep groove angle, bevel angle, root opening, and depth separate
A correct icon is not yet a correct decision.
Preparing the wrong member can make a joint impossible to assemble. Bevel grooves demand more attention to arrow convention and the physical detail than symmetric groove families.
What each mark tells you—and what it does not.
Use the third column as a stop-check. It prevents a familiar mark from turning into an unsupported assumption.
| Visual cue | What it tells you | What you must still verify |
|---|---|---|
| Single-bevel shape | One prepared face against a square/unprepared mate | Do not convert it into a symmetric V groove. |
| Arrow/broken-arrow convention | Helps assign the prepared member where the convention applies | Confirm against the detail and governing standard. |
| Angle and root-opening values | Define preparation geometry and fit-up | Neither value is weld length. |
One plate must stay square
A single-bevel callout points to a joint where only one member is accessible for preparation.
Use the arrow convention and joint detail to identify the member receiving the bevel. Read the angle, root opening, and depth from their stated positions.
The correct edge is prepared and the mating member remains square as designed.
How to read it without guessing
Recognize the vertical-and-sloped bevel symbol, establish the side, then use the arrow break or detailed view to identify which member receives the edge preparation.
- Identify the bevel-groove symbol rather than a V groove.
- Locate the exact member at the arrow tip.
- Use an arrow break or joint detail to identify the prepared member.
- Read groove angle, root opening, depth, and weld size separately.

DECIDING CHECKLook for the J-shaped elementary symbol and radius detail.Three mistakes that change the instruction
Preparing both members
Preparing both edges creates a V-type joint rather than the specified single bevel.
Reversing the member
An asymmetric groove on the wrong member changes fit-up and may make the joint impossible to assemble.
Confusing angle types
Read whether the value is the bevel angle or complete groove angle in the governing convention.

Standards and editorial basis
This guide teaches common AWS-style drawing interpretation. It is educational material, not a substitute for the purchased standard, project specification, code, WPS, or qualified engineering direction.
Editorial method. Original training diagrams, worked decisions, misconception checks, and questions are written for learning—not copied from a standards table. Production interpretation must still follow the governing documents.
