超声相控阵技术对不同厚度对接焊缝表层缺陷的定位

简要介绍了常规超声波检测和超声相控阵检测的特点。以超声相控阵技术为研究对象，对不同厚度对接焊缝表层缺陷的定位进行了试验研究。验证结果表明，超声相控阵检测技术能够实现对不同厚度对接焊缝表层缺陷的精确定位，提高了工作效率。超声相控阵检测技术可实现A扫、S扫等不同扫查方式的对比，使得对缺陷的判定更直观、更具有说服力，并且能够实现整个扫查过程全数据的存储，便于后期的处理和追溯。

Ultrasonic Phased Array Technology Positioning Analysis of Butt Weld Surface Defect with Different Thickness

In this article, it briefly introduced the characteristics of conventional ultrasonic testing and ultrasonic phased array technology. With ultrasonic phased array technology as the research object, the positioning of butt weld surface defect with different thickness was studied. The results showed that the ultrasonic phased array technology can realize accurate positioning for the butt weld surface defects with different thickness and improve working efficiency. It also can realize the comparison of different scanning modes, such as A mode, S mode and so on, make the determination of the scan results more intuitive and more persuasive, and can realize all data storage of whole scanning process, convenient for later processing and traceability.
