What position is a 4F performed in?

Explanation:
4F is the overhead fillet weld position. Fillet welds are designated by a number that climbs from flat to overhead: 1F is flat, 2F is horizontal, 3F is vertical, and 4F is overhead. The overhead designation means you weld in the orientation where gravity works against the molten metal, which makes control of the weld pool more challenging. You’ll typically focus on keeping a short arc length and a steady, small bead to maintain good fusion and profile. This is different from the other fillet positions, where gravity assists or acts differently on the molten metal.
