Non-destructive testing (NDT) is a method used to evaluate the properties of a material, component, or system without causing any damage. This technique is essential in various industries, including aerospace, construction, and manufacturing, as it helps ensure safety and reliability. NDT methods include ultrasonic testing, radiographic testing, and magnetic particle testing, each designed to detect flaws or irregularities. The primary advantage of NDT is that it allows for the inspection of materials while maintaining their integrity. This means that components can be tested repeatedly without affecting their performance or usability. By identifying potential issues early, NDT contributes to improved quality control and reduces the risk of failures in critical applications.
