What is the primary purpose of nondestructive testing (NDT)?
A. Damage components intentionally
B. Evaluate materials or components without harming
usability
C. Replace all engineering design
D. Increase scrap rates
Rationale: NDT inspects integrity while preserving the tested
item.
Which industry commonly uses NDT?
A. Agriculture only
B. Aerospace, construction, manufacturing, and energy
C. Restaurants only
D. Retail clothing only
Rationale: Many industries rely on NDT for quality and safety.
Which is a common NDT method?
A. Sanding
, B. Ultrasonic testing (UT)
C. Painting
D. Welding only
Rationale: UT is a major NDT technique.
Which method uses sound waves to detect flaws?
A. Magnetic particle
B. Ultrasonic testing
C. Visual testing only
D. Dye mixing
Rationale: UT uses high-frequency sound waves.
Which method uses X-rays or gamma rays?
A. Eddy current
B. Radiographic testing (RT)
C. Leak testing only
D. Torque testing
Rationale: RT images internal conditions using radiation.
Which method uses visible examination tools?
A. RT
B. Visual testing (VT)
C. UT only
D. Thermal cutting
, Rationale: VT uses direct or aided visual inspection.
Which method uses magnetic fields and particles?
A. Liquid penetrant
B. Magnetic particle testing (MT)
C. Hydrostatic only
D. Acoustic emission only
Rationale: MT detects surface/near-surface flaws in
ferromagnetic materials.
MT is generally limited to:
A. Plastic only
B. Ferromagnetic materials
C. Glass only
D. Wood only
Rationale: MT requires magnetizable materials.
Which method uses dye to reveal surface-breaking flaws?
A. RT
B. Liquid penetrant testing (PT)
C. UT
D. Vibration analysis only
Rationale: PT highlights open-to-surface discontinuities.
