The letter and number combinations of 1F and 2G mean

In welding notation, the digits indicate where the weld is placed (the position), and the letters indicate what type of weld is required. The position numbers map to common orientations (flat, horizontal, vertical, overhead), while the weld-type letters distinguish fillet from groove welds. So a designation for a fillet weld in the flat position in one context and a groove weld in the horizontal position in another are both signaling two things at once: how the weld sits and what kind of weld is needed. This information is separate from welding current settings, base material grade, or filler metal type, which are specified elsewhere.
