In certification tests (e.g., AWS D1.1):
The 2F position is used across multiple welding processes. Below are typical choices:
The is a specific classification within the American Welding Society (AWS) and ASME standards for Fillet Welds . 2f welding position
In 1F welding, the joint is tilted so the weld pool is supported entirely by the "V" of the metal. In 2F, gravity pulls the puddle toward the bottom plate, requiring the welder to actively "push" or "hold" the metal onto the vertical plate.
| Process | Typical Electrode/Filler | Polarity | Notes | | :--- | :--- | :--- | :--- | | | E7018 (Low-hydrogen) or E6013 | DCEP (DC+) | E6010/6011 can be used but produce more spatter. | | GMAW (MIG) | ER70S-6 (0.035" or 0.045") | DCEP (DC+) | Use a slight push angle. | | FCAW (Flux-Core) | E71T-1 (Gas-shielded) or E71T-11 (Self-shielded) | DCEP (DC+) | Great for thick plates; high deposition. | | GTAW (TIG) | ER70S-2 or ER70S-6 | DCEN (DC-) | Less common for fillets; used for thin or critical alloys. | In certification tests (e
In a 2F position, you typically have a "T-joint." One plate lies flat on the table (horizontal), and the other stands vertically upright. You are welding the triangular joint where these two plates meet.
In the 2F position, the welder deposits a bead into the corner of two pieces of metal that are oriented roughly 90 degrees to each other (like an "L" shape). The critical distinction is that , and the welding proceeds in the horizontal direction , but the face of the weld lies in a vertical plane. In 2F, gravity pulls the puddle toward the
If you are not careful, you will end up with a defect known as or overlap . This happens when the weld metal flows onto the bottom plate but doesn't fuse properly because it sagged too quickly, creating a lip that hides lack of fusion.
