Ultrasonic flaw detector is a kind of advanced science and technology as one of the inspection instruments, it plays a very important role in the treatment process of hospitals, and also can be fast and accurate inspection of parts and so on, in order to achieve the purpose of the use of safety. Compared with other detectors, the ultrasonic detector can complete the operation in a short period of time, and it is relatively simple to use, accuracy and sensitivity is not comparable to similar products.
(a) the working principle of ultrasonic flaw detection instrument
As the name implies, the ultrasonic flaw detection instrument mainly relies on ultrasonic unique properties to realize the detection of injuries, of course, this is mainly because of ultrasonic waves, it has a variety of waveforms, adapted to a variety of propagation medium.
When used, its transverse wave can accurately monitor the pipe, especially for those cracks, scratches and porosity can be accurately detected. Its longitudinal wave of metal ingots, billets, large forgings, etc. can be quickly detected, especially to detect the phenomenon of white spots, delamination. And its plate wave can detect the normal or not of the thin plate, and it is different from the surface wave can only detect some relatively simple shape of the casting whether there are defects. So the ultrasonic flaw detection equipment in use can be very good to help people's work.
(2) the advantages of ultrasonic flaw detection instrument
Because the use of ultrasonic detection, so this flaw detector has a strong penetrating power, in the work of the time it is even able to detect a few meters below the situation. And its sensitivity is also very good, in the use of it can be found in a short period of time other detectors can not find the reflector, and can be accurately confirmed on the material orientation, shape and size, and it is able to quickly react to the results of the detection. Compared with similar products, it only needs to be measured from the side of the object to be measured, which saves labor and time to a large extent, and its size is relatively small and easy to carry, the operation is not only relatively simple, but also has a very good safety performance.
(C) ultrasonic flaw detection instrument shortcomings
At present, the ultrasonic flaw detection instrument is not accurate enough for those who are irregular in shape or non-homogeneous materials, and it is not suitable for the measurement of the structure of the cavity.
In summary, it can be seen that the ultrasonic flaw detection instrument although there are certain shortcomings, but its overall performance is still very good. And it plays a very important role in industry, water conservancy projects, medical equipment, rescue equipment, etc., the use of generating wave flaw detector can improve the accuracy to a large extent, but also saves a lot of manpower, is a good choice in the process of actual operation.
