REAL PRACTICE QUESTIONS – SET 100 MOST
COMMON EXAM FREQUENTLY TESTED QUESTIONS
AND ANSWERS IN DETAILS 100% VERIFIED EXAM
HIGHLY RECOMMENDABLE FOR GRADE A+
1. A primary purpose of nondestructive testing (NDT) is to:
A. Improve material hardness
B. Detect discontinuities without damaging the part
C. Increase production speed
D. Replace destructive testing entirely
✔ B. Detect discontinuities without damaging the part
Explanation: NDT methods are specifically designed to evaluate materials
and components without causing damage, ensuring usability after
inspection.
2. Which NDT method is most suitable for detecting surface-breaking cracks in
ferromagnetic materials?
A. Ultrasonic Testing (UT)
B. Radiographic Testing (RT)
C. Magnetic Particle Testing (MT)
D. Eddy Current Testing (ET)
✔ C. Magnetic Particle Testing (MT)
Explanation: MT is highly effective for detecting surface and near-surface
discontinuities in ferromagnetic materials.
3. In Liquid Penetrant Testing (PT), the dwell time refers to:
A. Time for developer to dry
B. Time penetrant remains on surface
C. Time for cleaning
, D. Time for inspection
✔ B. Time penetrant remains on surface
Explanation: Dwell time allows penetrant to seep into discontinuities for
proper detection.
4. Which type of radiation is commonly used in industrial radiography?
A. Alpha particles
B. Beta particles
C. Gamma rays
D. Neutrons only
✔ C. Gamma rays
Explanation: Gamma rays and X-rays are widely used due to their high
penetration capability.
5. The primary advantage of ultrasonic testing over radiographic testing is:
A. Lower cost
B. Ability to detect internal flaws with precise depth
C. Simpler equipment
D. No need for calibration
✔ B. Ability to detect internal flaws with precise depth
Explanation: UT provides accurate depth and location information of
internal discontinuities.
6. A discontinuity that interrupts the typical structure of a material is called:
A. Defect
B. Indication
C. Imperfection
D. Flaw
✔ C. Imperfection
Explanation: An imperfection is any deviation from the ideal structure; it
may or may not be a rejectable defect.
7. In Eddy Current Testing, the depth of penetration depends on:
A. Voltage only
, B. Frequency and material conductivity
C. Temperature
D. Probe size only
✔ B. Frequency and material conductivity
Explanation: Lower frequencies increase penetration depth; conductivity
also influences eddy current flow.
8. In radiographic film, higher density indicates:
A. Less radiation exposure
B. More radiation exposure
C. No exposure
D. Poor processing
✔ B. More radiation exposure
Explanation: Darker film areas correspond to higher radiation exposure.
9. Which discontinuity is most likely formed during solidification?
A. Fatigue crack
B. Shrinkage cavity
C. Corrosion pit
D. Wear
✔ B. Shrinkage cavity
Explanation: Shrinkage occurs during cooling and solidification of molten
material.
10.In Magnetic Particle Testing, what is the purpose of magnetization?
A. Heat the material
B. Create magnetic flux leakage
C. Clean the surface
D. Increase hardness
✔ B. Create magnetic flux leakage
Explanation: Magnetization allows flux leakage at discontinuities,
attracting magnetic particles.
