What is non destructive inspection?

Non Destructive Inspection (NDI) refers to a range of testing and analysis techniques used to evaluate the properties of a material, component, or system without causing any damage. These methods are commonly used in industries such as aerospace, manufacturing, and construction to detect flaws, cracks, or defects that could affect safety or performance. Techniques include ultrasonic testing, radiography, magnetic particle testing, and dye penetrant inspection. NDI allows for thorough inspection and quality assurance while leaving the tested item intact and functional.
