Introduction

The phased array ultrasound referred to in this standard refers to the phased array ultrasound technique used in industrial testing. Although phased array ultrasound is a pulse reflection method Detection range, but in the sound field characteristics, detection applications, signal processing and imaging, performance and function, and many other aspects of phased array and conventional pulse inverse Shifting is very different. Phased array ultrasound using the probe is composed of a number of piezoelectric chips array transducer, through the electronic system to control the array of the various chips According to a certain delay in the law to launch and receive ultrasound, in order to achieve the beam scanning, deflection and focus and other functions. Using the scanning characteristics, phase Array technology can be in the probe does not move the case to achieve the detection of the area of the scan; the use of deflection characteristics, phased array technology can not only The probe does not move the case to achieve the detection of the area of the scan, and can stimulate the multi-angle beam on the detection area for a larger area Cover, so as to improve the detection efficiency and defect detection rate; the use of focusing characteristics, phased array technology can improve the sound field signal strength, echo signal amplitude And signal to noise ratio, thereby improving the defect detection rate, as well as the depth of the defect, the length of the measurement accuracy. Phased array ultrasound detection system is a high-performance digital instrument, to achieve the detection of the whole process of signal recording. Through the signal Processing, the system can generate and display high-quality images projected in different directions. Because phased array ultrasound with conventional ultrasound methods is based on pulse reflection detection, so in this standard test block, the detection level And the quantification of defects and other content part of the reference to the conventional ultrasound standards. But phased array technology and conventional ultrasound is a great difference between the advanced technology, So in the instrument system calibration, probe parameter selection, scanning and scanning methods, process parameter selection, gain compensation and sensitivity settings and other aspects of standard A new provision is given that is different from conventional ultrasound. Non - destructive testing of ultrasonic testing Phased array ultrasonography

1 Scope

This standard specifies the use of manual scanning or automatic (semi-automatic) scanning one-dimensional linear array phased array ultrasound technology application of the basic principles, The selection rules of the process parameters when testing, and the method of determining the location and size of the defect. This standard applies to the thickness of 6mm ~.200mm fine crystal steel welded joints. For other metal fine grain welding joints, in the test After changing the sound speed, you can also refer to this standard. For welded joints beyond the above range, the instrumentation is demonstrated by demonstration Sufficient detection capacity, but also refer to this standard. For austenitic stainless steel and other coarse crystalline welded joints, considering the signal to noise ratio and the speed of sound anisotropy Sexual impact, but also refer to this standard. For other structural parts, calendering parts, forgings, in the selection of appropriate test block, calibration methods and scanning methods, but also refer to this standard. The use of two-dimensional phased array ultrasound probe to detect, in considering the sound field characteristics and changes to the system calibration and detection of the impact, also Can refer to this standard.
