2g Welding Position [2021] Jun 2026

It is distinct from the position, which refers to a horizontal Fillet weld (commonly a "T-joint"). The 2G specifically refers to a butt joint or groove weld.

According to the American Welding Society (AWS) A3.0 standard, the 2G position is defined by the orientation of the weld axis and the plane of the weld.

The 2G welding position has several distinct characteristics:

This is where 2G becomes a true test of craftsmanship. The pipe is positioned horizontally (like a pipeline crossing a river), but the welder cannot roll it. The axis of the pipe is horizontal, and the weld is made around the circumference. It is distinct from the position, which refers

To excel in the 2G welding position, welders need to develop specific skills:

Working too hot or holding the arc too long at the top edge can "dig" into the metal without filling it back in, creating a structural weakness known as an undercut. A Guide to the 2G Weld Test - Triangle Engineering Using E7018 (Low Hydrogen) 1/8" rod at ~115-125 amps

For pipe welders, 2G (Horizontal Fixed) is where the physical layout of the joint forces a 90-degree axis shift relative to the welder’s body. This article dissects the mechanics, techniques, common pitfalls, and career implications of mastering the 2G position for both Plate and Pipe.
