High-frequency sound waves<\/strong> are sent out at a material to find material changes. A pulse produces an electrical pulse that causes a piezoelectric transducer to send out a sound wave. Reflected waves are transformed back into electrical signals by the transducer and analyzed. Its main applications are in thickness gauging and flaw detection.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Pulse Echo Technique:<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Ultrasonic inspections are largely performed<\/strong> by the pulse echo technique in which a single probe is used to both transmit and receive ultrasound. In addition to the fact that access is required from one surface only, further advantages of this technique are that it gives an indication of the type of defect, its size and its exact location within the item being tested.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

The major disadvantage is that pulse echo inspection is reliant upon the defects having the correct orientation relative to the beam in order to generate a returning signal to the probe and is not therefore considered fail safe. If the sound pulse hits the flaw at an angle other than 90o much of the energy will be reflected away and not return to the probe with the result that the flaw will not show up on the screen.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
