If there is no side significance for NDT, where is the NDT designation centered?

If there is no side significance for NDT, where is the NDT designation centered?

• A. On the left side.
• B. On the right side.
• C. On the reference line center.
• D. In the tail.

Answer: (C)

In welding symbols, non-destructive testing (NDT) requirements are shown near the weld symbol, and where no side significance is specified, the NDT designation is centered on the reference line. This centers the test on the weld itself without tying it to a particular side. If side significance were intended, the NDT mark would be placed to the left or right of the reference line to indicate which side must be tested. The tail is used for additional notes or information, not for the standard NDT indication.
