ULTRASONIC ANALYSIS METHODS
Ultrasonic inspection uses sound waves of short wavelength and high frequency to detect flaws or measure material thickness. It is used on welds in pressure vessels, structural steelwork and last but not least aircrafts.
Usually pulsed beams of high frequency ultrasound are used via a hand-held transducer which is placed on the specimen. Any sound from that pulse that returns to the transducer like an echo) is shown on a screen which gives the amplitude of the pulse and the time taken to return to the transducer. Defects anywhere through the specimen thickness reflect the sound, back to the transducer. Flaw size, distance and reflectivity can be interpreted.
Because of its complexity considerable technician training and skill is required.
PTS like to keep up to date with new technology and have invested in new “digital” ultrasonic equipment for all of the NDT operators.
PTS have inspection teams qualified in rope access to carry out this NDT discipline without the need for scaffolding, suspension platforms and cradles. Following our inspections we produce detailed reports, including drawings and photos, and these can be supplied in whatever form is required.
