AWS Certified Welding Inspector — FundamentalsWelding SymbolsMedium
A welding inspector encounters a blueprint with a welding symbol for a flare-bevel-groove weld. The symbol is placed on the arrow side of the reference line. What is the typical characteristic of the members being joined in this type of weld?
- AA pipe and a flat plate, both prepared with a V-groove.
- BTwo members, both with flat surfaces, forming a T-joint.
- CTwo flat plates forming a corner joint.
- DTwo members with curved surfaces, one being beveled.
Show answer & explanationAnswer & explanation
Correct answer: D. Two members with curved surfaces, one being beveled.
A flare-bevel-groove weld is typically used when joining a curved surface (e.g., a round bar or pipe) to a flat surface, where the curved surface forms the 'flare' and the flat surface is beveled to fit.
Why the other options are wrong
- A. This describes a standard V-groove weld, not a flare-bevel-groove.
- B. This often describes a fillet weld or single-bevel groove weld on a T-joint.
- C. This typically describes a fillet weld or a square-groove weld.
Flare-Bevel-Groove Weld
A type of groove weld used when one or both members being joined have a curved surface, where the natural curvature forms part of the groove.
- Typically used for joining a round bar/pipe to a flat plate.
- The 'flare' refers to the curved surface.
- The other member is usually beveled to fit the curve.
- Symbol is a curved line with a straight line.
Memory trick: Grooves are cut, flares are curved, J-U-V are shapes.
