nondestructive testing
Quick Summary
Nondestructive testing (NDT) is a crucial method for evaluating materials and products without causing damage. This is particularly important for costly or difficult-to-fabricate materials, or for finished products where destruction is unacceptable.123
NDT techniques include:
* Radiation methods: Using X-rays or gamma rays to detect internal flaws by passing radiation through the material onto photographic film.1
* Liquid penetrant testing: Employing dyed or fluorescent liquids to reveal surface cracks and flaws. An electrically charged liquid variation exists for nonmetals.2
* Infrared thermography: Detecting flaws by observing how heat is absorbed or dissipated across a material's surface, useful for assessing adhesive bonds.3
These methods allow for the identification of defects, ensuring the integrity and quality of materials and components.123
