AW Inspection provides an experienced and robust Ultrasonic inspection service to a wide range of industries across Somerset and the South West. UI Inspection is a non-destructive test method that uses sound waves to detect cracks, weld grooves, fractures and defects in parts and materials.

Electronic transducers transmit high-frequency sound waves to a material, these sound waves bounce back crystal-clear images, which reveal key characteristics about a material’s properties. Ultrasonic Inspection can be used to determine the thickness of the test object, for example, to monitor pipework corrosion.

Ultrasonic Inspection Testing

Ultrasonic testing is often performed on steel and other metals and alloys. It is a form of non-destructive testing used in many industries including power generation, aerospace, steel fabrication, automotive, and other transportation sectors.  Because of the portability of the equipment and variety of methods available, ultrasonic testing allows for inspection of parts that are large, irregularly shaped, or unable to be transported.


  • High penetrating power, which allows the detection of flaws deep in the part.
  • High sensitivity, permitting the detection of extremely small flaws.
  • Only one surface need be accessible.
  • Greater accuracy than other non-destructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
  • Some capability of estimating the size, orientation, shape and nature of defects.
  • Non-hazardous to operations or to nearby personnel and has no effect on equipment and materials in the vicinity.
  • Capable of portable or highly automated operation.
