Non-Destructive Testing
Non-destructive testing is a known non-invasive technique that is used to assess the physical integrity or assure the quality of a material in terms of flaws,discontinuities, or defect detection.
Five NDT were performed in the Atomic Energy Center:
i. Dye-penetrant Test (PT)
ii. Magnetic particle Test (MT)
iii. Ultrasonic Test (UT)
iv. Eddy current Test (ET)
v. Radiographic Test (RT)
Objective:
i. Detection of surface defect
ii. Assessment of surface defect
iii. Evaluation of surface defect
i. Detection of surface defect
ii. Assessment of surface defect
iii. Evaluation of surface defect
Applications of NDT
i. Detection of flaw and Evolution
ii. Determination of location and size of flaw
iii. Leak Detection
iv. Dimension verification of components
v. Structure and micro structure characterization
vi. Estimation of mechanical and physical properties
vii. Stress and dynamic response measurement
viii. Material sorting and chemical composition determination
ix. Assessment of strength of materials
x. Quality control
Advantages of NDT
i. It is reliable
ii. It offers reassurance
iii. It is cheap
iv. Immediate result can be found
v. Destruction of material is not needed
vi. Fast preparation
vii. 3D data acquiring
viii. High accuracy
ix. Very sensitive
x. Easy to perform
xi. Independent of weather conditions
