What is 5G and 6G welding?

Welds with a 1 are flat position, 2 is horizontal, 3 is vertical and 4 is overhead. F stands for fillet weld, while G is a groove weld .

There are mainly four types of pipe welding positions- 1G – Horizontal Rolled Position. 2G – Vertical Position. 5G – Horizontal Fixed Position . 6G – Inclined Position.

With this key in mind, what 4G mainly covers is Overhead Groove Welding . Meaning, the ability of welding metals to be joined together in an overhead position. Since this is the fourth, that most likely means that it is the hardest to do from the rest of the welding positions.

6G Position The pipe is in a fixed position, so the welder must move around the pipe to perform the welding . This is an advanced welding position that requires a great deal of experience and technical expertise.8 Eki 2019
