AWS Welding Inspection and Testing Certification Practice Test

Which welding position involves the pipe being horizontal?

1. 1G

2. 2G

3. 5G

4. 6G

The correct answer is: 1G

The welding position that involves the pipe being horizontal is referred to as 5G. In this position, the pipe is placed horizontally, and the welder operates in a fixed position around it. The 5G position allows for more accessibility when welding, as the welder can move around the pipe while maintaining a consistent horizontal orientation. In comparison, 1G is typically associated with flat position welding where the pipe or plate is horizontal, but the welding occurs on a flat surface, differing from the horizontal orientation of the pipe. The 2G position involves welding flat, but with a vertical orientation, and 6G refers to a position where the pipe is at a 45-degree angle, combining aspects of both vertical and overhead welding practices. Understanding these positions is critical in welding, as they directly affect the technique, skills required, and the type of welds that can be executed effectively in each scenario.
