What is a 2F?

What is a 2F?

• A. Horizontal Fillet
• B. Vertical Fillet
• C. Flat Fillet
• D. Overhead Fillet

Answer: (A)

In welding terminology, the F indicates a fillet weld, and the number shows the joint’s orientation relative to gravity. A fillet weld joins two pieces at about a 90-degree angle, and the position describes how the joint sits. A horizontal fillet means the joint lies in a horizontal plane and the weld bead runs horizontally as you weld, requiring good control to prevent sag in the molten metal. This is what 2F denotes. The other fillet positions differ: flat fillet is welded on a flat plane, vertical fillet on a vertical plane, and overhead fillet from above. So the 2F designation corresponds to a Horizontal Fillet.
