Which code designates a pipe in the fixed horizontal position?

• A. 5
• B. 1
• C. R
• D. G

Answer: (A)

In pipe welding, position codes indicate how the pipe is oriented during the weld. The fixed horizontal pipe position is represented by the number five, typically seen as 5G to note the groove weld on a fixed-horizontal pipe. This numeric designation specifically encodes the straight, horizontal orientation of the pipe, which is why it’s the correct choice. The other options correspond to different setups or aren’t used to indicate this pipe orientation, so they don’t describe the fixed horizontal pipe position.
