Field calibration of full focused phased array technology

  • 摘要: 检测系统的校准是实施超声检测必不可少的步骤。以往各种超声检测技术的校准都是基于A扫的,其步骤多、耗时长、精度差。通过研究全聚焦相控阵的声场特性和信号特性而提出的“场校准”技术路线,具有原理易懂、过程简单、操作快捷、精度高、自动化程度高等优点。阐述了场校准的原理和基本过程,并结合试验结果,指出场校准可以简化焊缝超声检测的操作,可以全面提升全聚焦相控阵技术的优势。
    Abstract: Calibration of the detection system is an essential step in implementing ultrasonic testing. In the past, the calibration of various ultrasonic detection technologies was based on A-scan by following many prescribed steps, and is time-consuming and of poor accuracy. The "field calibration" technical route proposed by studying the ultrasonic field characteristics and signal characteristics of a fully focused phased array has a series of advantages such as easy-to-understand principles, simple processes, fast operation, high accuracy, and high degree of automation. This article describes the principle and basic process of field calibration, and gives some test results. It is pointed out that the application of field calibration can greatly simplify the operation of ultrasonic inspection of welds with high accuracy, which can comprehensively enhance the advantages of full focus phased array technology.
