Introduction

Like the A-type conventional detector, the phased array ultrasonic is based on the pulse reflection method for detection, and the same flaw quantitative and qualitative methods are used. bit method. However, the phased array ultrasonic detector is a high-performance digital instrument, which can record the signal of the whole detection process. The system can generate and display high-quality images projected in different directions, so its unique measurement calibration and verification methods need to be specified. Certainly. GB/T 42399 aims to pass the testing methods and acceptance criteria for phased array ultrasonic detectors including instruments, probes and combined systems Standards are stipulated, so as to unify the technical requirements of products, so that they can be better applied in actual production and testing. GB/T 42399 "Performance and Inspection of Phased Array Ultrasonic Equipment for Nondestructive Testing Instruments" is divided into the following three parts. --- Part 1.Instruments. The purpose is to specify the detection frequency of multi-channel phased array ultrasound in the range of 0.5MHz~10MHz The detection method and acceptance criteria of the main technical performance of the detector. --- Part 2.Probes. The purpose is to specify the use of contact method or liquid immersion method, the center frequency range is 0.5MHz~10MHz The detection methods and acceptance criteria for the main technical performance of phased array probes that need to be inspected after fabrication is completed. --- Part 3.Combined system. The purpose is to specify the use of linear phased array probes, contact (with or without wedge) or water immersion, center The performance detection method of phased array combination equipment (that is, connected instruments, probes and cables) with a frequency in the range of 0.5MHz~10MHz laws and acceptance criteria. The three parts of GB/T 42399 "Performance and Inspection of Phased Array Ultrasonic Equipment for Nondestructive Testing Instruments" are independent of each other, but they echo each other and form a into a complete set of standards. Non-destructive testing instrument phased array ultrasonic equipment Performance and inspection part 3. combined systems

1 Scope

This document describes the inspection methods and acceptance criteria for the inspection of combined equipment (ie instruments, probes and connecting cables). This document is applicable to contact type (with or without wedges) or liquid immersion linear array phased array probes with a center frequency of 0.5MHz~10MHz. Ultrasonic testing system. This detection method is applicable to users in the field or workshop environment. Its purpose is to verify that the system is working correctly, Beam characteristics or check for system performance degradation. This test method is not intended to prove the suitability of the system for a particular application, but to Demonstrate the ability of the combined device to generate an ultrasonic sound beam according to the setup. The scope of this document does not include application-specific device calibration, which is generally covered by the testing process. This document does not contain the following. --- Ring array; ---Aperture sequences with different numbers of array elements; --- The settings of transmission and reception are different (such as excitation aperture, effective number of array elements, delay); ---Adopt a single-array unit signal post-processing technology that is more complex than the simple delay rule (for example. full matrix acquisition).
