ABSTRACT

Nondestructive testing technology is of great significance for ensuring the quality of industrial products and production safety. Among them, eddy current testing, as an important nondestructive testing method, has been widely used in many fields. With the increasing requirements for testing efficiency and accuracy in industrial production, the automated development of eddy current testing has become an inevitable trend. This paper focuses on the role of intelligent sensors in promoting the automated development of eddy current testing in nondestructive testing. The basic principles of intelligent sensors and eddy current testing are elaborated in detail. The application advantages of intelligent sensors in the automation of eddy current testing are analyzed in depth, including high-precision detection, adaptive and real-time monitoring, as well as automated integration and collaborative working capabilities. At the same time, the key technologies in this process are discussed, such as sensor optimization, signal processing and analysis, and automated control and communication technologies. By presenting application cases of intelligent sensors in fields such as aerospace, automotive manufacturing, and the power industry, their remarkable effectiveness is demonstrated. The research results show that intelligent sensors have greatly improved the automation level of eddy current testing, enhanced testing efficiency and accuracy, and reduced labor costs. However, currently, there are still problems such as high sensor costs and insufficient adaptability to complex environments. In the future, with the continuous progress of technology, intelligent sensors will play an even more important role in the automation of eddy current testing, promoting the development of nondestructive testing technology to a higher level.
