NDT Techniques
Nondestructive testing (NDT) techniques are methods used to examine the integrity of materials and structures without causing damage. They help identify defects like cracks, corrosion, or voids to ensure safety and durability. Common NDT methods include ultrasonic testing (using sound waves to detect flaws), radiographic testing (X-rays or gamma rays to view inside), magnetic particle testing (detecting surface and near-surface flaws with magnetic fields), dye penetrant (applying dye to surface cracks), and eddy current testing (using electromagnetic induction for surface and subsurface inspection). These techniques are essential for maintaining safety in industries like aerospace, manufacturing, and infrastructure.
