If the same examination type is to be performed on both sides of the joint, the letter designation must appear on both sides.

• A. On both sides
• B. On one side
• C. Only on the tail
• D. Only on the reference line

Answer: (A)

In welding symbols, the annotation that indicates the examination or testing type is placed in specific locations to show where it applies. When the same examination is required on both faces of a joint, the letter designation for that NDE must be shown on both sides of the joint symbol. This makes it clear to everyone involved that testing is mandatory on both sides, preventing any ambiguity and ensuring the weld is inspected from both faces as required. If the test were needed on only one side, the designation would appear on just that side, signaling a single-side requirement. Placing the designation on the tail or on the reference line would imply a different instruction and would not accurately convey a double-sided requirement.
