AWS Certified Welding Inspector — FundamentalsWelding SymbolsEasy
A blueprint shows a welding symbol for a single-bevel groove weld. The symbol is placed on the arrow side of the reference line. What does this indicate about the preparation of the joint?
- ABoth members are beveled.
- BThe beveling is done on the member indicated by the arrow.
- CNo beveling is required for this joint.
- DThe beveling is done on the member opposite to the arrow side.
Show answer & explanationAnswer & explanation
Correct answer: B. The beveling is done on the member indicated by the arrow.
For a single-bevel groove weld symbol placed on the arrow side of the reference line, the beveling is to be performed on the member to which the arrow points.
Why the other options are wrong
- A. This would indicate a double-bevel groove weld symbol.
- C. The presence of a groove weld symbol indicates that some form of preparation (like beveling) is required.
- D. This would be the case if the symbol was on the other side of the reference line.
Groove Weld Symbol Placement
The placement of a groove weld symbol (e.g., bevel, V, U) on the reference line indicates which member of the joint is to be prepared (e.g., beveled) for the weld.
- Symbol on arrow side: Preparation on arrow-side member.
- Symbol on other side: Preparation on other-side member.
- Symmetric groove symbols (e.g., V-groove) typically imply preparation on both members if on both sides of the reference line.
Memory trick: Where the symbol sits, there the bevel fits.
