How to use LK ultrasonic flaw detector?
LK ultrasonic flaw detector is a kind of portable industrial non-destructive flaw detector. It is fast, convenient, non-destructive, and can accurately detect various defects inside the construction site. I believe many people are not familiar with it and don't know how to use it. Let's learn the use method of LK ultrasonic flaw detector with the editor.
LK ultrasonic flaw detector can be used in the laboratory, also can be used in the project site, can be widely used in the manufacturing industry, iron and steel metallurgy industry, metal processing industry, chemical industry and other fields that need defect detection and quality control. It can also be widely used in aerospace, railway transportation, boiler and pressure vessel and other fields for safety inspection and life assessment, and it is also a necessary instrument for nondestructive testing industry.
1. After connecting the instrument 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 key to preset the year, month and day.
3. Enter the preset channel, select the flaw detection mode and probe type, and input the nominal value of the probe chip size (the angle probe also needs to input the leading edge distance).
4. Place the probe on the csk-i a test block and adjust the "gain" key of the instrument.
5. Measure or use the "zero point" key to preset the zero point offset of the probe.
6. Measure or use the "sound speed" key to preset the speed (sound speed) of sound wave propagation in the workpiece.
7. Use the "K value" key to preset the K value when using the angle probe.
8. Use the "sound path" key to select the scale definition and size of the instrument.
9. When surface compensation is needed, use the "compensation" key to compensate.
10. After setting, press the "function" key to enter the working state.
11. Apply coupling agent on the surface of the workpiece to be tested, place the probe on the workpiece to be tested, move the probe to check whether there is any defect in the workpiece, freeze the defect found with "quantitative" key, and record with "record" key.
12. After the test, turn off the main power switch of the instrument, remove the probe, wipe off the oil stain on the instrument and probe surface, and then install it into the instrument box.
Well, the above is about the use of LK ultrasonic flaw detector, I hope these can help you. If you want to know more, please keep an eye on us and we will update it in time.
