Abstract

Features:

A portable test system for manual ultrasonic testing with on-line


• monitoring probe position and beaming direction by airborne ultrasound
  
• monitoring acoustic coupling by low frequency noise
  
• true-to-scan recording and display of actually inspected areas of probe trace
  
• echo processing with true-to-scale recording and display of the inspected region presented as projection defect imaging in the top and side with colour coded echo amplitudes<
  li>intelligent post-processing of recorded data, including reviewing defect images withdifferent sensitivity thresholds, sizing and zooming of defect images

The significance of the lecture

Using mechanics-free monitoring of probe location and beaming direction (airborne ultrasound) with simultaneous monitoring of acoustic coupling, by evaluating low frequency noise passed through the object, a true-to-scale presentation of the inspected region is recorded and displayed with all the relevant indications, including the documentation of the active probe trace.
The classical manual ultrasonic test is decisively supplemente: presentation of the entire probe movement as proof that complete test object scanning has been made. The lecture describes the technology applied, its advantages compared with conventional ultrasonic testing and describes the opportunities of using the system as a replacement for radiography testing.
