NDT activities involve inspecting components or materials to detect defects, cracks, corrosion, porosity, or deformation without damaging the part.

This process includes surface preparation, selecting an appropriate method such as ultrasonic testing, magnetic particle testing, dye penetrant testing, or radiographic testing, performing the test, and analyzing the results to determine the component's quality or condition. All findings are recorded for evaluation of maintenance, repair, or operational decisions, ensuring equipment reliability and safety.
