1. The primary responsibility of an NDT Level II technician is to:
A. Perform NDT only under constant supervision
B. Develop new NDT methods
C. Interpret and evaluate test results according to applicable
codes
D. Approve engineering design changes
Answer: C
Rationale: Level II technicians are qualified to interpret,
evaluate, and document NDT results in accordance with codes
and standards.
2. Which document provides written instructions for performing a
specific NDT method?
A. Code of construction
B. Procedure
C. Specification
D. Quality manual
Answer: B
Rationale: A procedure gives step-by-step instructions on how an
NDT method is to be performed.
,3. In ultrasonic testing, sound energy that returns to the transducer
from a reflector is called:
A. Attenuation
B. Refraction
C. Back reflection
D. Echo
Answer: D
Rationale: Reflected ultrasonic energy received by the
transducer is known as an echo.
4. The main purpose of couplant in ultrasonic testing is to:
A. Increase sound velocity
B. Eliminate air between transducer and test surface
C. Reduce surface roughness
D. Improve probe durability
Answer: B
Rationale: Couplant removes air gaps, allowing efficient
transmission of ultrasonic energy into the test material.
5. In radiographic testing, image sharpness is primarily affected by:
A. Film size
B. Source-to-film distance
C. Radiation wavelength
D. Exposure time
Answer: B
Rationale: Increasing source-to-film distance reduces geometric
unsharpness and improves image sharpness.
6. Which type of discontinuity is best detected by radiographic
testing?
A. Tight cracks parallel to the beam
B. Planar lack of fusion
, C. Volumetric defects such as porosity
D. Surface-breaking cracks
Answer: C
Rationale: RT is most effective for detecting volumetric
discontinuities like porosity and slag inclusions.
7. In magnetic particle testing, leakage fields are strongest at:
A. Smooth surfaces
B. Subsurface voids
C. Changes in magnetic permeability
D. Discontinuities interrupting magnetic flux
Answer: D
Rationale: Discontinuities disrupt magnetic flux, creating
leakage fields that attract magnetic particles.
8. Which material property is required for magnetic particle testing?
A. Electrical conductivity
B. Ferromagnetism
C. High density
D. Smooth surface finish
Answer: B
Rationale: MT can only be performed on ferromagnetic
materials.
9. Penetrant testing is most effective for detecting:
A. Subsurface defects
B. Volumetric internal defects
C. Surface-breaking discontinuities
D. Changes in material hardness
Answer: C
Rationale: PT detects defects that are open to the surface, such
as cracks and porosity.
