Which number and letter combination does the AWS assign to the flat welding position?

The flat welding position is identified by the combination of the number one and the letter G (1G) according to the American Welding Society (AWS) classification system. In this system, the "1" denotes that the weld is performed in a flat position, which is generally the easiest position to weld in due to gravity assisting in material placement and uniform weld pool management.

In the flat position, the workpiece is horizontal, and this allows for effective control over the weld puddle, making it ideal for beginners and proficient welders alike. The G stands for "groove," indicating that the welding is typically done on groove welds in this position. This standardization helps welders to communicate effectively about welding positions across various settings and projects, ensuring clarity in training, certification, and job specifications.
