Non-Destructive Testing (NDT) is a method used to evaluate the properties of a material, component, or assembly without causing any damage. This technique is essential in various industries, including aerospace, construction, and manufacturing, as it helps ensure safety and reliability. Common NDT methods include ultrasonic testing, radiographic testing, and magnetic particle testing. NDT allows for the detection of flaws, cracks, or other irregularities in materials while preserving their integrity. By using advanced technologies and techniques, inspectors can assess the quality of products and structures, ensuring they meet safety standards and performance requirements.
