Operation and usage instructions for MUT600B fully digital ultrasonic flaw detector:
The surface temperature of the workpiece should not be too hot and should be less than 120 ℃.
The surface roughness of the workpiece should not be too large, otherwise it will affect the detection effect. The tested surface of the workpiece must show a metallic luster and be flat and smooth.
The surface of the workpiece needs to be coated with an appropriate amount of coupling agent to facilitate inspection.
Probe preparation: Before starting the instrument, select a suitable probe based on the shape of the workpiece and the nature of the defect, and connect the probe to the probe socket at the top of the instrument.
◇ Select the system status of the instrument. The different combination states of the transmission and reception systems of the flaw detector are suitable for different detection tasks. For specific requirements, selecting a certain combination of states will optimize the echo waveform, improve the signal-to-noise ratio, and achieve better resolution or optimal flaw detection sensitivity.
Before testing, the parameters of the instrument and probe must be calibrated.

　　Operating procedures and precautions for ultrasonic flaw detector
In order to perform non-destructive testing on key components of production equipment, the correct use of the MUT600 B-ultrasonic flaw detector requires the following operating procedures:
1、 Testing personnel requirements
Testing personnel must undergo professional technical training from the competent department and obtain the corresponding qualification certificates before engaging in the corresponding testing work.
2、 Instrument requirements
1. The operating frequency range of the MUT600 B-ultrasound ultrasonic flaw detector is 1-5 MHz, and it displays linearly within at least 80% of the full scale on the display screen.
2. The horizontal linear error shall not exceed 1%, and the vertical linear error shall not exceed 5%.
3. During use, the horizontal and vertical linearity of the instrument should be measured at least once every three months.
3、 Testing method
1. After connecting the MUT600 ultrasonic flaw detector and probe, turn on the main power switch of the flaw detector and press the operation key to set the system status.
2. Press the operation keys to preset the year, month, and day.
3. Enter the preset channel, select the flaw detection method and probe type, and enter the nominal size value of the probe chip (for oblique probes, also enter the leading edge distance).
4. Place the probe on the CSK-IA test block and adjust the instrument's "gain" button.
5. Measure or use the "zero" button to preset the zero offset of the probe.
6. Measure or use the "sound speed" button to preset the speed at which sound waves propagate in the workpiece (sound speed).
7. When using a tilt probe, use the "K value" key to preset the K value.
8. Select the scale definition and size of the MUT600 B-ultrasound ultrasonic flaw detector using the "Sound Path" button.
9. When surface compensation is required, use the "Compensation" button for compensation.
10. After the setting is completed, press the "Function" button to enter the working state.
11. Apply coupling agent on the surface of the tested workpiece, place the probe on the tested workpiece, move the probe to check for defects, and freeze any defects found with the "Quantitative" button and record them with the "Record" button.
12. Record the defects detected during inspection.
13. After the inspection is completed, turn off the main power switch of the MUT600 B-ultrasound ultrasonic flaw detector, remove the probe, wipe off the oil stains on the surface of the instrument and probe, and then install it in the instrument box.
4、 Precautions
1. Coupling agent: Coupling agents such as engine oil, paste, glycerin, and water should be used, which have good sound transmission and do not damage the detection surface
2. Testing surface
a. The determination of the detection surface and detection range should ensure that the entire area of the inspected part of the workpiece is inspected. For steel plates, forgings, steel pipes, and bolt components, the entire workpiece should be inspected, while for fusion welds, the entire weld seam should be inspected.
b. The inspection surface should pass the visual inspection, and all rust, splashes, and dirt that affect ultrasonic testing should be removed. The surface roughness should meet the inspection requirements.
3. Detection coverage: During detection, the entire inspected area of the workpiece should be scanned as much as possible, and the coverage rate of each scan of the probe should be greater than 15% of the probe diameter.
4. The movement speed of the probe should not exceed 150mm/s. When using an automatic alarm device for scanning, this restriction is not applicable.
5. Scanning sensitivity: It should be at least 6dB higher than the reference sensitivity.
6. Coupling compensation
a. Surface roughness compensation: When detecting and quantifying defects, compensation should be made for the energy loss caused by surface roughness.
b. Attenuation compensation: During detection and defect quantification, compensation should be made for the decrease in detection sensitivity and defect quantification error caused by material attenuation.
c. Surface compensation: For workpieces with curved detection surfaces, reference blocks with the same or similar curvature radius as the workpiece should be used for comparison and curvature compensation.
7. According to the industry standard JB4730-94 of the People's Republic of China.
