1G, 2G, 3G, 4G, 5G, and 6G refer to different welding positions for testing welders’ skills. "G" stands for "groove weld," and the numbers indicate the position: 1G (flat), 2G (horizontal), 3G (vertical), 4G (overhead), while 5G and 6G are pipe welding positions—5G (horizontal fixed pipe) and 6G (inclined pipe at 45 degrees), with 6G being the most challenging.
