1G, 2G, 3G, 4G, 5G, and 6G refer to welding position codes used to describe the orientation of the weld joint and the position of the welder. "G" stands for "groove weld," and the numbers indicate different positions: 1G (flat), 2G (horizontal), 3G (vertical), 4G (overhead), 5G (horizontal pipe), and 6G (inclined pipe at 45 degrees), with 6G being the most challenging.
