Question

how can ultrasound be used to detect the defect in metal block

Answer 1

Answer: Ultrasounds can be used to detect cracks and flaws in metal blocks. ...Ultrasonic waves are allowed to pass through the metallic block and detectors areused to detect the transmitted waves. If there is even a small defect, theultrasound gets reflected back indicating the presence of the flaw or defect.

Answer 2

Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components are used in the construction of big structures like buildings, bridges, machines and scientific equipments. The cracks or holes inside the metal blocks, which are invisible from outside reduces the strength of the structure. Ultrasonic waves are allowed to pass through the metallic block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of the flaw or defect.
