Which code designates a pipe in a 45-degree fixed position?

• A. 1
• B. 2
• C. 6
• D. G

Answer: (C)

Pipe-welding position designations indicate how the pipe is held during a weld, and the fixed pipe position at a 45-degree angle is called 6G. The "6" signals the fixed orientation of the pipe, while the "G" stands for groove weld. This position is the standard test setup because it locks the pipe in a 45-degree angle, requiring precise control and consistency around the entire circumference. That combination—fixed 45-degree pipe orientation—is what this item is testing, so the code corresponding to it is the one that uses the six in the designation. The other symbols describe different positions or generic groove welding and do not designate this specific fixed 45-degree pipe setup.
