application scope of ultrasonic flaw testing equipment

The quality of ultrasonic flaw detection has always been a difficult problem, and it still mainly relies on the experience and analysis and judgment of flaw detection personnel, and the accuracy is poor. The development of modern artificial intelligence disciplines makes it possible to realize automatic defect characterization of instruments. Using pattern recognition technology and expert system, input a large number of various feature quantities of known defects into the sample library, so that the instrument can accept human experience, and after learning, it has the ability to automatically characterize defects.

When the ultrasonic wave propagates in the tested material, the acoustic characteristics of the material and the change of the internal structure will have a certain influence on the propagation of the ultrasonic wave. Ultrasonic detection methods usually include penetration method, pulse reflection method, tandem method, etc. The portable ultrasonic flaw detector usually emits ultrasound to the measured object (such as industrial materials, human body), and then uses its reflection, Doppler effect, transmission, etc. to obtain the internal information of the measured object and process it into an image.

Foreign companies such as GE Testing Technology, R/D TECH, Siemens, IMASONIC, etc. have launched commercialized portable ultrasonic phased array testing equipment and large-scale ultrasonic phased array testing systems. For example, the GE Phasor XS phased array ultrasonic flaw detector can perform simultaneous multi-angle inspections at one time, and can switch between conventional ultrasonic and phased array modes at will.

When using the phased array mode, the sector scanning function of Phasor XS greatly improves the defect detection capability. Only one scan is required to cover a large area of inspection, which greatly improves the efficiency of inspection work. Operators can easily achieve multiple angles and depths of focus with one probe without changing probes or wedges.

The development speed of portable ultrasonic flaw testing equipment is extremely rapid, and its flaw detection efficiency and flaw detection rate have a qualitative leap.

In the ultrasonic flaw detector, the Doppler effect method is to use the Doppler frequency shift effect that occurs when ultrasound encounters a moving object to obtain the moving direction and speed of the object; the transmission method is to analyze the ultrasonic penetration through the tested object. The application of the internal characteristics of the object obtained from the subsequent changes of the object is still in the development stage; here is the most widely used method to obtain the internal characteristics of the object through the reflection method.
