Phased Array Ultrasonik Testing (PAUT) is a non-destructive testing methode used to decret and criteria defects infices in materials. It providees detaild information about thee size and location of defects, which ch is essential for assessing structural integrale. Thi article explains the basic steps to calculate flaw size and position using PAUTT data.

Zrozumiałe thee Data

PAUT generates a serie of ultradźwiękowe signals that ar e displayed as B- scans or C- scans. These images show thee reflection points where influents are detected. The data includes the time of fight, amplitude, and the position of thee probe during testing.

Kalkulating Flaw Location

Te flawe 's position is determinate te by analyzing thee time of flaght and thee probe' s position. The distance from thee probe te to thee flaw is calculated using thee sound velocity in thee material ante te time it takes for thee ultrasondonic wave to travel to thee flaw and back.

Te formuły używane is:

(Speed of Sound in Materiial) x (Time of Flight / 2)

Bo combinang thi with the probe 's known position, the flaw' s exact location with thee material can be mapped.

Kalkulating Flaw Size

Te wszystkie te zmiany, które są estymated based on thee amplitude of thee reflected ultradźwiękowe signal. Larger phers tend to produce higher amplitude signals. Calibration with known flaw sizes helps improwizuj dokładność.

Dodatek, że width of thee echo in thee A- scan can indicate thee flaw 's extent. By measuring thee duration of thee reflectod signal, thee approxiate size of thee flaw can be inferred.

  • Analizuję te ultradźwiękowe sygnały, żeby zidentyfikować odbicie flaw.
  • Oblicz te dystance te te flaw using time of fight and sound velocity.
  • Ustalić, że te flaw 's size based on amplitude and echo width.
  • Map thee flaw 's location with ith material for assessment.
