Pulse Echo Inspection

Pulse Echo (UT) The ultrasonic pulse-echo method, or pulse-echo method, is a non-destructive testing technique using ultrasonic waves to find defects in materials.

A typical pulse-echo UT inspection system consists of several functional units, such as the pulser/receiver, transducer, and a display device. Ultrasonic waves are mechanical vibrations and have a frequency greater than 20 KHz. depending on the velocity of sound in a material and the frequency

The degree of reflection is representative of the depth the wave has travelled into the surface. There is a direct proportional relationship between the distance travelled by the wave, the length of delay between pulse transmission and echo reception.

This can be used to detect surface flaws, such as cracks, voids or inclusions of foreign materials, also used to measure the thickness of walls and diameter of bars.

The ultrasonic pulse-echo method uses two types of waves
