Non Destructive Testing

Nondestructive testing or NDT is a wide group of analysis and techniques used in science and industry to evaluate the properties and integrity of a material, component, or piece without causing damage to the specimen or piece being tested. The terms Nondestructive Examination (NDE), Nondestructive Inspection (NDI), and Nondestructive Evaluation (NDE) are also commonly used to describe these techniques. Because NDT does not permanently alter the physical conditions of the piece being inspected, it is a highly valuable technique that can save both money and time in product assessment, troubleshooting, and research. Some NDT methods include ultrasonic, electromagnetic, radiographic, remote visual inspection, guided waves, magnetic particle, penetrant testing, etc. All these methods have been subject to significant improvements during the last decade, therefore making available more accurate tools in the field of materials examinations.
