A Non Destructive Inspection (NDI) is a type of testing that evaluates the integrity of a material, component, or system without causing damage. This type of inspection is often used in the aerospace, automotive, and construction industries to ensure the safety and reliability of products and components. NDI is also used in the medical field to detect diseases and other medical conditions. The process of NDI involves the use of various techniques such as radiography, ultrasonic testing, eddy current testing, magnetic particle testing, and visual inspection. These techniques are used to detect any flaws or defects in the material, component, or system that could lead to failure or other problems. NDI is an important part of quality control and helps to ensure that products and components are safe and reliable.
