1G, 2G, 3G, 4G, 5G, and 6G refer to welding position codes used to describe the orientation of the weld and the workpiece. "G" stands for "groove weld," and the number indicates the position: 1G (flat), 2G (horizontal), 3G (vertical), 4G (overhead), 5G (pipe horizontal, fixed), and 6G (pipe at 45° angle, fixed), with 6G being the most challenging. These positions are used to test and certify welders' skills.
