The ___ test is a nondestructive testing procedure.

The ___ test is a nondestructive testing procedure.

• A. Radiographic
• B. Visual
• C. Magnetic Particle
• D. Ultrasonic

Answer: (D)

Nondestructive testing includes techniques that evaluate a weld or part without altering or destroying it. Visual inspection checks surface condition, radiographic testing uses X-ray or gamma rays to reveal internal features, magnetic particle testing highlights surface and near-surface defects in ferromagnetic materials, and ultrasonic testing sends high-frequency sound into the material to detect internal flaws and measure thickness. Because none of these methods damages the part, all are nondestructive testing procedures. Filling the blank with ultrasonic testing is a valid example, especially in welding, where it is widely used to uncover internal weld flaws and assess thickness, and it often complements other NDT methods to give a fuller picture of quality.
