Flat Position (1G and 1F)
The easiest type to perform is the flat position, which is also sometimes called the downhand position. It involves welding on the top side of the joint. In this position, the molten metal is drawn downward into the joint. The result is a faster and easier weld.
In 1G and 1F, the number 1 refers to the flat position, while the letter G stands for a groove weld and letter F stands for a fillet weld.
Horizontal Position (2G and 2F)
This is an out of position welding position. It’s a more difficult position compared to the flat position and it requires more skill from the welding operator to do them well.
2G is a groove weld position that involves placing the weld axis in a horizontal plane or approximately horizontal. As for the face of the weld, it should lie in an approximately vertical plane.
2F is a fillet weld position, in which the welding is done on the upper side of the surfaces that is approximately horizontal that lies against a surface that is approximately vertical. In this position, the torch is usually held at a 45-degree angle.
