The examination PA uses a single probe which contains multiple elements (16-128) to send ultrasonic angle beams through the test object. Each individual element can be pulsed to send where timed phase. This produces several beam angles, which combined form a network. This network of beams identify changes in the material, such as cracks or nclusions that can be viewed on screen and identified. Time of flight diffraction is one of the most advanced techniques of ultrasound examination. The method is based on the phenomenon of diffraction of the ultrasonic waves that create virtual images of the discontinuities found in the examined parts. This method has a higher degree of accuracy than any other method of ultrasound and it is considered to be one of the fastest NDT methods because a weld can be examined in a single scan.
APPLICATIONS:
•Weld examination;•Control of plates, forgings;•The examination of metallic pieces.
ADVANTAGES:
•The examination can be performed using the encoder that recordsreal-time control, and location of discontinuities.•The results can be viewed immediately and saved / stored in theequipment.•Possibility of automatic control using weld rover.•The ability to show multiple images at the same time, resulting inthe rapid identification of discontinuities.•Configuring the examination with the help of Estbean Tols andSetup Bilder.•Mobile equipment, examination can be made at home.
