Presentation of results

Below are two presentations of results

  • presentation of the results of instantaneous during the test run and possibly the archival record
  • presentation of the results pooled so in the course of the study (part ± steaks) and (full) if the archival record

Figure 6 View of the screen during testing hollow axle or archival record

Screen during the test is divided into four areas and illustrates the instantaneous state of research. In the upper part of the screen shows two current waveforms defectoscopic (Imaging A - two heads). Under longitudinal section axis. Oblique sections define the axis of the head of research 'in przód'i head in the "rear". In the lower right corner of the screen at the cross-section jeer indicates the instantaneous angular połażenia survey sites. Grey marked areas are areas not yet explored. Presented imaging (original) is in cylindrical coordinates.

Visible detected six standard cuts on the pattern exactly in their places of location, ie the axis of the most dangerous sections.

The device consists of a shield of probes, flaw detector and bracket-adapter. Moreover, it may be equipped with a ring with the probes, as well as other research probes (e.g., welded connection). Shield of ultrasonic probes (Figure 1 and Figure 2) is used for testing, from the carrier face. Probes are placed on the target at distances resulting from the geometric analysis in a sustainable manner. The shield is designed individually for each type of axle depending on its geometrical dimensions. The shield is also arranged normal to the research probe along the axis. Also mounted device for measuring the rotation angle (inclinometer), making it possible to record the course of the study.

  • "horns" (battery) power supply,
  • faceplate with power outlets and additional probes,
  • three control buttons,
  • two signaling LEDs.

Figure 2 CUD BO-Fi. View from the bottom, visible:
  • shield of probes (6 pcs, 2MHz, Ø25mm),
  • numbers of probes and angles (e.g. 1 | 0 ° and 2 | 5,2 °),
  • centering pin.

Figure 1: A screenshot of the time axis using a wireless visible flaw:
The upper-left part of the screen shows the flaw with the current indication (type A), the right side represents the recorded amplitude axis circuit, the lower are the length of the axis. Imaging involves two incisions and shown as an echo on a scale percentage of the screen for the test section as a function of the angle. In this example there are two reference notches of different depth of 0.5 mm.

individual circles on imaging (Fig. 1) are:

  • gray color indicates the outer surface of the test axis (corresponding to the amplitude of 0%, the amplitude of 100% means a means wheel)
  • color zielonm designated registration threshold set at 20% of screen height. All indications are within range marker above this threshold will be registered
  • red color indicates acceptance threshold (40% of the screen) and any of its cross. All indications above the threshold of acceptance should be considered as a potential indication of unacceptable discontinuities
  • marked in blue while the tested location on the periphery of the axis together with an indication of any indication of the amplitudes above the threshold of registration.

  • profiled probe with inclinometer and resistance ring,
  • probes ring with inclinometer.
