Where is a percentage of NDE requested?

• A. To the left of a NDE symbol.
• B. To the left of an NDE designation.
• C. To the right of an NDE designation.
• D. Above the NDE designation.

Answer: (C)

In welding symbols, the way much of the weld is to be subjected to non-destructive testing is shown directly with the NDE designation and the extent of testing. The method of NDE is listed after the NDE designation, and the percentage describing how much of the weld (or how many welds) is to be examined is placed to the right of that designation. This position keeps the information about the testing method separate from the scope of testing, making the instruction clear at a glance. So you’ll see something like the NDE designation followed by a percentage to its right, which tells you the portion to be tested. Placing the percentage to the left or above the designation would not conform to standard notation and could create confusion about what is being specified.
