What is the designation of a horizontal weld test?

The designation of a horizontal weld test is indeed 2G. This label indicates a specific welding position as defined by the American Welding Society (AWS) standards. In the context of welding positions, the first digit prior to the letter specifies the position of the pipe.

In the case of 2G, the "2" denotes a horizontal position, meaning the weld is performed on the horizontal plane. This position is crucial in testing a welder’s ability to work on joints that lie flat and typically involves added challenges such as controlling the weld pool due to gravity.

Understanding these designations is important for anyone in the field, as welders must be proficient in various positions to ensure sound welding practices across different applications. The other designations refer to different positions, with "1G" indicating a flat position, "3G" indicating a vertical position, and "2B" not being a recognized designation in this context. Therefore, the recognition of 2G for horizontal welding reflects industry standards for assessing welding capabilities.
