A reference line symbol can carry multiple NDE types on which locations?

• A. Only on the left side.
• B. Only on the right side.
• C. On any side or in the center.
• D. Only above.

Answer: (C)

Nondestructive examination indicators on welding symbols are flexible in where they’re placed around the reference line. You can carry multiple NDE types on the same reference line and put those indicators on either side of the weld symbol, or even in the center, to show exactly which part of the joint is inspected or if the inspection applies to the whole joint. This allows you to specify different tests for different sides or for the entire weld, without being restricted to one fixed position. That’s why the best answer is that the NDE indicators can be on any side or in the center. Placing them only on one side or only above would not fully convey which parts of the joint are inspected or whether multiple tests apply to the same weld.
