Mattel ultrasonic flaw detector AVG AVG curve curve preparation method is described in rule versus distance reflector, amplitude, equivalent size. Different industries and different product defect tolerance, in order to improve efficiency, before testing, we have produced a corresponding mark in accordance with industry standards, that curve. Role is to determine a benchmark to defect to the defect compartment and quantification. For example: When a piece that appears wounds wave height in Ⅱ area, which is between AVG when offline and neutral, detectors Which is good, as the diameter of the line is set to 1mm, midline diameter 2mm, ultra-exploration training courses, So the size of the defect is between 1mm and 2mm. Production Method: 1, according to sound path key flaw prices, the detection range is adjusted to 250mm, which is slightly larger than the value of the test piece thickness, so that both make a return appears in the display area can also take advantage of the display area width, clearly observed wave occurs between the beginning and the first wave echo injury. Press twice DAC / AVG AVG enter production options. 2. Press the F2 key, in reference option, the reference type into a flat-bottomed hole, the reference aperture is a defect in the test block hole diameter of 2.0mm. 3. Press the F1 key, Changping District detector, press the Enter key to select AVG production, then the upper right area of ??the waveform display that displays the words "AVG", that enter the AVG production process. 4, the probe on the CS-1-5 test block, moving the probe to a depth of 200mm looking at the highest echo φ2 hole, adjust Gate A state, locked at φ2 200mm flat bottom hole echo, by automatic gain so that echo height reached 80%. 5, to ensure that the probe does not move, return AVG menu select record the point, press the Enter key, the instrument can automatically record the echo location and height. 6. Press the F3 key to enter the aperture settings, if necessary, are input AVG online, AVG line, the aperture AVG offline. Such as: 3mm, 2mm, 1mm. 7, return AVG menu, select and press OK to finish creating the save. At this point a depth of 200mm, flat bottom hole diameter of 2mm as a benchmark to 3mm aperture as on-line, 2mm and 1mm aperture aperture as neutral as standard AVG curve will be produced off the assembly line. Mattel MUT600B flaw detector preparation MUT600B is a fully digital portable ultrasonic flaw detector that can quickly and easily, without damage, within the workpiece accurately a variety of defects (cracks, inclusions, porosity, etc.) to detect, locate, evaluate and diagnosis. Both for the laboratory, but also for engineering field testing. Inspection preparation: l surface temperature can not overheat, should be less than 120 ℃. l surface roughness can not be too large, otherwise it will affect the testing results. The measured surface of the workpiece to be exposed metallic luster, smoothing and polish. l Coupling: surface coated with an appropriate amount of coupling agent is required to facilitate testing. Probe preparation: Before starting the instrument, depending on the nature of the workpiece shape, defect select the appropriate probe, the probe tip is coupled to the instrument probe socket. Select the instrument system status. Emission detector, the receiving system combined state in which different for different detection tasks. For specific requirements, select a combination of a certain state, will play an echo waveform optimization to improve the signal to noise ratio, obtain better resolution action or optimal detection sensitivity. Before testing, the instrument must be calibrated probe parameters. Changping District, US Tyco _ _ flaw detectors classification provided by the Beijing Science and Technology Co., Ltd. US-Tyco.
