Ultrasonic Examination

Ultratest is the leading specialist in ultrasonic inspections on a wide range of materials and products.
Ultrasonic testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection / evaluation, dimensional measurements, material characterisation and more. Ultrasonic examination is most conducted on steel and several other metals and alloys including composites. Ultrasonic examination is commonly used in industries like aerospace, automotive and other transportation industries.
One of the main advantages of ultrasonic examination in comparison to other non destructive testing methods is that it offers greater accuracy in verifying the depth of internal flaws and the thickness of parts with parallel surfaces.
To demonstrate the general inspection principle, a typical pulse echo inspection configuration as illustrated below will be used.
