What is the "area of interest" on a weld radiograph?
- A . The entire radiograph minus 2 in. (50.8 mm) from the edges
- B . Only the area of contrasting density
- C . The specific portion of a radiograph that needs to be evaluated

- C . Record the change on the existing WPS.
- D . List the change as a supplement to the WPS.
When verifying that the filler metal selection is appropriate for the base metal being welded, an inspector should consider:
- A . Chemical composition.
- B . Tensile strength to be higher than the base metal.
