What is Non-destructive Testing (NDT)?
Non-destructive testing (NDT) is a method to examine, test, and assess the material, its constituents, configuration, or variations in features without damaging the usefulness of the product or its parts.
Nowadays non-destructive tests are advantageous in construction, fabrication, and in-service examination to confirm the reliability and durability of the product, manage the process of manufacturing, reduce the cost of production, and maintain a consistent level of quality.
Non-destructive Testing has numerous advantages that include the parts under examination are not damaged during the process, the faulty pieces are fixed rather than substituted.
Non-destructive testing is reproducible and various tests can be combined to correlate the results thus making it a precise technique of examination.
The Non-destructive Testing Procedure is inexpensive because it can help to identify the error and repair it without damaging the item.
Most of the procedures are harmless for operators but still, some are required to take place under monitored settings.
It can help to avoid any casualties by certifying structures, components, and machinery are unharmed.
The NDT also provides the operators' satisfaction and assurance that the device is running smoothly, stopping any forthcoming mishaps and establishing all the means for life extension.
A few standard NDT Techniques that are used include Electromagnetic Testing (ET), Magnetic Particle Testing (MT), Radiographic Testing (RT), Liquid Penetrant Testing (PT), Ultrasonic Testing (UT), Visual Testing (VT), Eddy Current Testing (ECT).
Each of the testing techniques has its benefits and drawbacks.
With technological developments in imaging and digital regulators, several other techniques have been established that including Phased Array Ultrasonic Testing (PAUT), Time of Flight Diffraction (ToFD), Digital Radiography, and Computed Radiography.
Non-destructive Testing (NDT) Training
