non-destructive evaluation (NDE)

Non-destructive evaluation (NDE) is a set of methods used to inspect and assess the condition of materials and structures without causing damage. It helps identify flaws, cracks, or defects that could lead to failure, ensuring safety and reliability. Techniques include ultrasound, radiography, magnetic or optical methods, and eddy current testing. NDE is essential in industries like aerospace, construction, and manufacturing to verify integrity without dismantling or damaging the tested object. This process allows for maintenance, repairs, and safety checks while preserving the item's usefulness.
