Pipe Welding 6g Position Jun 2026

The refers to welding a pipe that is fixed at a 45-degree angle (inclined). The pipe is not rotated during welding; the welder must move around the pipe to complete the joint. The “G” stands for “groove weld.”

Stick welding is the most common method for the fill and cap passes in 6G testing because it works well in out-of-position scenarios. pipe welding 6g position
