Paper Title:
System for Detecting the Defects of Steel Tubes Based on Electromagnetic Acoustic Technology
  Abstract

According to the electromagnetic acoustic technology, an automatic system was constructed to detect the defects of steel tubes. On the basis of analyzing the principle of detecting the defects of steel tubes by the electromagnetic acoustic technology, an electromagnetic acoustic transducer was designed to transmit and receive the electromagnetic acoustic signals. The data were acquired by the high-speed data acquisition card and transferred to computer by PCI bus, and then analyzed and processed by computer. In addition, the selective frequency and amplification technology was used to process the weak received signal, which improved the anti-jamming ability of the system. Experiments on steel tubes with different diameter through-hole were performed, and the res
