Standard pipe welding positions are classified by the American Welding Society (AWS) and ASME using alphanumeric codes that describe the orientation of the pipe and the type of weld.
The hierarchy of pipe welding positions moves from the gravity-assisted to the technically demanding 6G . For a professional welder, proficiency in the 6G position is the ultimate demonstration of skill, proving the ability to control the weld pool in any orientation gravity can present. welding positions pipe
