4f Welding Position Full May 2026
Assuming you are welding a T-joint (two plates forming a 90° angle) with the web vertical and the flange horizontal, follow these steps.
For larger fillet welds (e.g., 10mm leg length), multiple passes are needed. 4f welding position full
Typical sequence (T-joint, overhead):
Each pass should be cleaned thoroughly (chip/brush) to remove slag that may drip onto the next pass. Assuming you are welding a T-joint (two plates
| Feature | Description | |---------|-------------| | Workpiece Orientation | The member receiving the weld is vertical (90° to horizontal). | | Weld Axis | Horizontal (parallel to the floor). | | Weld Face | Lies in a vertical plane. | | Gravity Effect | Molten metal tends to sag or drip downward due to gravity. | | Typical Joint Types | T-joints, lap joints, corner joints (where one plate is vertical). | Each pass should be cleaned thoroughly (chip/brush) to
