Nondestructive Testing (NDT) is a method used to evaluate the properties of materials, components, or assemblies without causing any damage. This technique helps identify defects, measure thickness, and assess structural integrity, ensuring safety and reliability in various industries, including aerospace, construction, and manufacturing. Common NDT methods include ultrasonic testing, radiographic testing, and magnetic particle testing. Each method uses different principles, such as sound waves or electromagnetic fields, to detect flaws. By employing NDT, companies can maintain quality control and extend the lifespan of their products while minimizing waste and costs.
