The NDT (Non-destructive testing) is a widely used inspection solution for numerous types of industries in the plant operations, manufacturing, construction and other engineering sectors. Which is a branch of engineering concerned with methods of detecting and evaluating flaws in the materials. The NDT produces no damaging effects on the material or structure under test and assists with guaranteeing safe operation, quality control, and assessing plant life.
Defects or Flaws may present as cracks or inclusions in welds and castings or variations in structural properties—all of which have the potential to lead to loss of strength or failure in service. There are many different types of Non-Destructive Testing methods available, each of which has both advantages and disadvantages.
CONVENTIONAL NON-DESTRUCTIVE TESTING METHODS
- ET – ELECTROMAGNETIC TESTING
- MT – MAGNETIC PARTICLE TESTING
- PT – LIQUID PENETRANT TESTING
- UT – ULTRASONIC TESTING
- VT – VISUAL TESTING
SPECIALIZED NON-DESTRUCTIVE TESTING METHODS
- ACFM – ALTERNATING CURRENT FIELD MEASUREMENT
- AUT – AUTOMATED ULTRASONIC TESTING
- PAUT – PHASED ARRAY ULTRASONIC TESTING
- STRUCTURAL INTEGRITY INSPECTION – SII
- TOFD – TIME-OF-FLIGHT DIFFRACTION METHOD
- VERTICALITY SURVEY / SLOPE SURVEY
