Welding Positions Pipe ~upd~ File
| Designation | Pipe Orientation | Rotation Allowed? | Weld Orientation | | :--- | :--- | :--- | :--- | | | Horizontal | Yes (Rolled) | Flat | | 2G | Vertical | No | Horizontal | | 5G | Horizontal | No | Flat, Vertical, Overhead | | 6G | 45-Degree Angle | No | All (Complex) |
These codes dictate the angle of the pipe, the direction of travel, and the orientation of the weld joint. Mastering these positions is a requirement for any pipe welder seeking certification. welding positions pipe
| Position | Official Name | Pipe Axis | Weld Type | Difficulty | Common Application | | :--- | :--- | :--- | :--- | :--- | :--- | | | Horizontal Rolled | Horizontal | Butt or Fillet | Easiest | Shop fabrication, bench work | | 2G | Vertical Fixed | Vertical | Butt | Moderate | Pipe spools, vertical risers | | 5G | Horizontal Fixed | Horizontal | Butt | Hard | Structural pipe, racks, no rotation | | 6G | Inclined Fixed | 45° angle | Butt | Hardest | Critical process piping, oil & gas | | Designation | Pipe Orientation | Rotation Allowed
As the welder works, the pipe is rotated so the welding always happens at the top (flat) surface. | Position | Official Name | Pipe Axis
