What Is 5g Welding ((link)) -

In welding, there are several standard positions that are used to describe the orientation of the weld joint. These positions are designated by a number and a letter. The number indicates the position of the weld, and the letter indicates the type of weld (e.g., groove, fillet, etc.).

| Position | Pipe Orientation | Pipe Rotation | Welder Movement | Difficulty | |----------|----------------|---------------|-----------------|-------------| | (rotated) | Horizontal | Rolls (rotates) | Stationary | Easiest | | 2G | Vertical | Fixed | Horizontal around pipe | Moderate | | 5G | Horizontal | Fixed | Vertical up/down & around | Difficult | | 6G | 45° inclined | Fixed | All positions (inclined) | Most difficult (test standard) | what is 5g welding

The pipe does not rotate. The welder must weld in all three basic positions around the pipe’s circumference: In welding, there are several standard positions that

In the world of welding certifications and pipe fitting, position codes are the language that defines skill level. Among these, is considered one of the most critical and widely used certifications. | Position | Pipe Orientation | Pipe Rotation

refers to a pipe welding position where the pipe is fixed in a horizontal orientation (its axis is horizontal), but the welder must move vertically around it to make the weld. The “G” stands for Groove weld (as opposed to fillet weld).

Most welders take a per ASME Section IX or AWS D1.1 (structural) / API 1104 (pipeline).

The primary difficulty of 5G welding is managing gravity. As the welder moves around the pipe, gravity affects the molten weld pool differently at each clock position.
