AWS Certified Welding Inspector — FundamentalsWelding SymbolsMedium
A welding inspector is reviewing a drawing for a T-joint. The welding symbol specifies a single-bevel groove weld. The symbol for the groove weld is placed on the arrow side of the reference line. What is the correct interpretation of the preparation of the joint for this weld?
- AThe beveling should be done on the member the arrow points to.
- BNo beveling is required, only a root opening.
- CThe beveling should be done on the other member that the arrow points to.
- DBoth members should be beveled.
Show answer & explanationAnswer & explanation
Correct answer: A. The beveling should be done on the member the arrow points to.
For a single-bevel groove weld symbol placed on the arrow side of the reference line, the beveling is to be done on the member that the arrow points to. This design ensures proper fit-up and weld access.
Why the other options are wrong
- B. A groove weld inherently requires preparation for the groove, including beveling for a single-bevel type.
- C. If the beveling were on the other member, the symbol would be on the other side of the reference line.
- D. If both members were beveled, it would be a double-bevel groove weld, indicated by a different symbol.
Groove Weld Arrow Side Prep
When a single-bevel or single-J groove weld symbol is on the arrow side of the reference line, the preparation (beveling) is on the member the arrow points to.
- Arrow side symbol = arrow side member prep.
- Other side symbol = other side member prep.
- Ensures proper joint geometry.
Memory trick: The arrow points to the part that gets the cut.
