NDT Techniques, or Non-Destructive Testing Techniques, are methods used to evaluate the properties of materials, components, or assemblies without causing damage. These techniques help identify defects, measure material 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, magnetic particle testing, and liquid penetrant testing. Each technique utilizes different principles, such as sound waves or electromagnetic fields, to detect flaws. By employing NDT techniques, organizations can maintain quality control and extend the lifespan of their products while minimizing waste and costs.
