AWS Welding Inspection and Testing Certification Practice Test

The pipe welding position in which the axis of the pipe lies fixed at a 45-degree angle is?

1. 1G

2. 2G

3. 5G

4. 6G

The correct answer is: 6G

The correct response is based on the understanding of pipe welding positions as defined by the American Welding Society (AWS). In the 6G position, the pipe is fixed at a 45-degree angle, which makes it a challenging position for welders because they must weld in all directions around the pipe. This position is used to simulate field conditions where pipes are often installed at various angles, and the welder is required to maneuver the welding gun effectively to achieve a sound weld throughout the entirety of the joint. To differentiate, the 1G position denotes a flat position where the pipe is horizontal, 2G indicates a vertical position with the pipe upright, and 5G refers to a horizontal pipe position that can rotate. None of these other positions incorporate the 45-degree angle aspect, which is why they do not match the description given in the question.
