What Is Non-destructive Testing? Non-destructive testing (NDT) also known as ‘positive testing’.
As its name implies, non-destructive testing means testing of materials without destroying them. It is a kind of a testing approach in which the testing is performed to cover only the positive cases to confirm that the software behaves properly and returns the expected results as per the product requirement. It is one of the best courses to do if you want to get a high profile job in abroad or India in oil & gas, petroleum, aircraft, refinery, etc. It is commonly used in the area of aerospace engineering, mechanical engineering, civil engineering, electrical engineering, system engineering, and medicines. EXAMPLES OF DESTRUCTIVE TEST:
Visual Testing: Advantages:
Disadvantages: · Ferromagnetic materials only · Alignment of the magnetic field is critical · Demagnetization required after the test · Surface coatings can mask defects · Pre- and post-cleaning necessary · Messy · Subjective: dependent on operator interpretation · Difficult to automate · Ultrasonic Testing (UT): Advantages
Disadvantages:
Non Destructive Testing provides cost-effective and reliable analysis under realistic conditions. Each NDT Testing services has certain capabilities and limitations and often more than one technique is used to cover various parts. Increasing the availability of robotic scanners improve the speed of testing large surfaces, hence minimizing the testing time.
