Welding For Horizontal Position. In this position the weld axis lies horizontally and the weld faces the vertical plane. Starting at the bottom or 6 oclock position weld upward to the 3 oclock position.
3G UphillPF Position Vertical. The weld axis is horizontal. It is harder than the 1F position.
This position is almost the same as the 1G position only the pipe cannot be rotated.
As for the face of the weld it should lie in an approximately vertical plane. As for the face of the weld it should lie in an approximately vertical plane. 2S position is similar to horizontal position welder will move the electrode in horizontal plane. Welding Position 1G is the easiest pipe welding position as the pipe is in horizontal position.
