What is an ultrasonic flaw detector used for?

Ultrasonic flaw detection can potentially be applied to any standard engineering material to uncover hidden cracks, voids, porosity, inclusions and similar discontinuities.While most tests involve steel and other structural metals, the flaw detector can also be used on plastics, composites, fiberglass and ceramics.

How does ultrasound detect defects in metal?

These waves travel through the medium in the desired direction at a specific speed.When these waves hit a boundary with a different medium, they are transmitted back.This is the principle behind ultrasonic flaw detection.

What is the name of the ultrasonic flaw detector?

Ultrasonic Nondestructive Testing, also known as Ultrasonic Nondestructive Testing or UT for short, is a method of characterizing the thickness or internal structure of a test piece by using high frequency sound waves.Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT

How does ultrasound detect metals?

The ultrasound is passed through one end of the metal block and a detector is placed at the other end.The defective part of the metal block does not allow ultrasonic waves to pass through.As a result, it will not be detected by the detector.Therefore, ultrasonics can be used to detect defects in metal blocks.
