AWS Certified Welding Inspector — FundamentalsWelding SymbolsEasy
A welding inspector is reviewing a drawing for a T-joint. The welding symbol specifies a single-bevel groove weld on the arrow side. To ensure proper fit-up, what specific preparatory detail is indicated by the bevel symbol's orientation?
- AThe base metal on the arrow side must be beveled.
- BThe root opening must be zero.
- CBoth base metals must be beveled.
- DThe base metal on the other side must be beveled.
Show answer & explanationAnswer & explanation
Correct answer: A. The base metal on the arrow side must be beveled.
For a single-bevel groove weld, the symbol indicates that only one of the members is prepared with a bevel. When the symbol is on the arrow side, the member pointed to by the arrow is the one that receives the bevel preparation.
Why the other options are wrong
- B. Root opening is a separate dimension shown on the symbol, not directly indicated by bevel orientation.
- C. This would be a double-bevel groove weld, with symbols on both sides.
- D. This would be indicated by the symbol being above the reference line.
Single-Bevel Groove Weld
A groove weld where only one of the joint members is prepared with a single bevel.
- Symbol below reference line = arrow side member beveled.
- Symbol above reference line = other side member beveled.
- Bevel symbol orientation indicates which plate is beveled.
Memory trick: Bevels point the way to the prepared plate.
