Mattel using ultrasonic flaw FAQ 1. Q: The same conditions and procedures, why the results are different ultrasonic testing of man-made and external factors greater impact on the testing results, although on the surface it seems, testing conditions and operations, but the result is not the same, this is normal. Because there are some conditions that can not be controlled and repetitive, such as coupling, handle, probe orientation and position, and so on. Just make sure whether the difference is within the allowable range. 2. Q: Why are some parameters on the screen parameter area has been a slight change either in the presence or absence of echo displays, amplitude values ??are displayed on the screen may appear minor changes, this is normal. The reason is due to the presence of an echo in the gate minor fluctuations. If the probe is not connected, it may be the reason the instrument noise. 3. Q: Why make DAC curve, but a low amplitude close: poor coupling probe and test block is not found the highest wave; effect of the probe near-field region (eg: K1 probe with 10mm aperture ratio sounding sounding 20mm echo hole is low.) Mattel ultrasonic flaw detector set MUT600B MUT600B wave probe is a fully digital portable ultrasonic flaw detector that can quickly and easily, without damage to accurately perform a variety of defects (cracks, inclusions within the workpiece, porosity etc.) to detect, locate, evaluate and diagnose. Both for the laboratory, but also for engineering field testing. Nominal way probe K value (probe angle) shear wave angle probe in three ways: First, the angle of incidence to the nominal longitudinal wave; the second is transverse to the nominal angle of refraction; Third K value () to nominal. The instrument uses the latter two. The instrument displays either the angle of refraction, K values ??can also be displayed. You can freely switch between the two display modes, switching mode to: select probe angle project, repeatedly button or click the knob, you can switch the display mode. K values ??are displayed when the probe, ultrasonic flaw detector price, the probe K value of the status bar on the display in the form of: KX.XX; to refraction angle display, the display on the status bar in the form of: ∠XX °. Probe K value and the angle of refraction interrelated. Different angle probe its angle of refraction is not the same, the K value is different. E.g., an angle probe K value K2, then the refraction angle of 63.4 °; K1 corresponding refraction angle 45 °; K1.5 refraction angle corresponding to 56.3 °. Straight probe angle of refraction of 0 °, metal detectors, then the K value is also 0, so straight probe K value calibration is not required. Each commercial probes have a group of data symbols to illustrate its "identity." For example: denoted as 2.5P13 × 13K2 probe, the logo can be seen from it is a oblique probe, K represents the slope, which is 2 ,, the piezoelectric wafer size is 13 × 13mm square chip, the frequency of 2.5MHz. For commercial nominal value of the probe, in particular K values ??and the actual values ??are some errors. When testing to pinpoint the location of the defect, Gansu detectors, after the probe bias calibration must be measured K value or probe angle. Usually the first angle probe input nominal value, when the K value after the calibration value will be measured refraction angle; if known actual refraction angle, you can directly input.
