The Basque Research centre IK4-IDEKO has developed a state-of-the-art ultrasonic inspection system f
or the train wheel. This system secures a sound condition of train wheels and is thus a significant contribution to rail transport safety. The device was delivered to CAF recently and its use allows the manufacturer to become an approved supplier of rolling stock in Italy, as it meets the demanding homologation standards of this country. \\\\r\\\\n
The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.
Pulse thermography is a non-contact test method that is ideal for
the characterization of thin fil
ms and coatings or the detection
defects. With a remarquable short test time and a high detection
sensitivity, the Telops TESTD-PT is the perfect tool for non-
destructive testing. With such high frame rates, it is even
to investigate highly conductive or diffusive materials.
