The method of ultrasonic testing allows to determine a wide range of features and defects of the tested material. Let’s dwell only on the detection of internal flaws, among which it is:
- Search and identification of reflectors.
- Determination of its location.
- Measurement of its sizes.
- Identification of its features (orientation, type, etc.).
What is a “reflector”?
For better understanding, let us give a synonym for the word “reflector” – “discontinuity”.
This concept is interpreted as “improper object in the structure of a testeded object, which may be a defect.”
In fact, only an accurate determination of the location of the defect, its analysis, makes it possible to argue that this is a flaw that may affect the functionality of the testing object.
The term “discontinuity” is used until there are confirming facts that the detected reflector is an unacceptable “defect”.
