Correct Answer: B. Evaluating radiographic quality using visible wires

Short Explanation:
Wire IQIs use wires of known diameter. The required wire must be visible on the radiograph.

82. In radiographing a 1-inch butt weld, the penetrameter is normally placed on:

A. Film side
B. Source side
C. Cassette side only
D. Viewer side

Correct Answer: B. Source side

Short Explanation:
IQIs are normally placed on the source side. If placed on the film side due to inaccessibility, the lead letter F is required.

83. What type of flaws may be detected by liquid penetrant testing?

A. Surface discontinuities open to the surface
B. Deep internal slag only
C. Internal porosity only
D. Subsurface lamination only

Correct Answer: A. Surface discontinuities open to the surface

Short Explanation:
PT detects only discontinuities that are open to the surface.

84. What type of flaws may be detected by magnetic particle testing?

A. Surface and near-surface discontinuities
B. Only internal slag
C. Only volumetric porosity
D. Only non-metallic defects

Correct Answer: A. Surface and near-surface discontinuities

Short Explanation:
MT detects surface and slightly subsurface discontinuities in ferromagnetic materials.

85. On a set of cassettes for a seam just radiographed, the lead location markers are taped to the cassettes. Are these radiographs acceptable?

A. Yes, because the markers are close to the film
B. Yes, if the density is correct
C. No, location markers should be placed on the part being examined
D. Yes, if the film is clear

Correct Answer: C. No, location markers should be placed on the part being examined

Short Explanation:
Location markers must appear as radiographic images and should be placed on the part, not merely taped to the cassette.
