Defects in metal blocks do not allow ultrasound to pass through them, and they are reflected. This fact is used to detect defects in metal blocks. Ultrasound is passed through one end of a metal block, and detectors are placed on the other end. The defective part of the metal block does not allow ultrasound to pass through it. As a result, it will not be detected by the detector. Hence, defects in metal blocks can be detected using ultrasound.
