Which welding symbol indicates a flare V shape?

• A. Fillet weld
• B. Groove weld
• C. Square weld
• D. Flare V

Answer: (D)

Understanding welding symbols starts with recognizing the shown geometry. A flare V indicates a V-shaped groove with flared edges at the root. The symbol visually represents a V groove, but with the added flare, which distinguishes it from a plain V or other shapes. That specific depiction is why it’s used to indicate a flare V weld. The other shapes—fillet weld (triangular symbol for a fillet between surfaces), square weld (square edge), and groove weld in general (covers various groove forms without the flare detail)—do not show the distinctive flare V geometry. So the symbol that explicitly shows a V shape with a flare is the one that indicates a flare V weld.
