Special Issue Information

Dear Colleagues,

Electromagnetic nondestructive testing is playing a significant part in nondestructive testing around the world. The developing usage of electromagnetic nondestructive testing has put forward new requirements and challenges for promoting research in related fields. Therefore, this Special Issue aims to introduce new ideas and experimental results from the principle, characterization and mechanism of electromagnetic nondestructive testing to sensors, signal processing and intelligent evaluation in practical applications.

Magnetic excitation, electromagnetic characterization of damage or tension, magnetoelectric coupling, magnetic coupling, electromagnetic nondestructive testing equipment and applications related to electromagnetic nondestructive testing are also topics of interest.

This Special Issue will publish high-quality original research papers in the following fields:

  • Principle and mechanism of electromagnetic nondestructive testing method;
  • Electromagnetic characterization of electromagnetic excitation and damage or tension;
  • Magneto-electric coupling and sensing mechanism and technology;
  • Electromagnetic nondestructive testing electrical signal processing;
  • Electromagnetic nondestructive testing digital signal processing and intelligent evaluation;
  • Electromagnetic nondestructive testing sensors, equipment and applications.

Special geometric features and complex working environments render the internal defects of small-diameter thick-walled steel pipes “easy to expand, difficult to detect”. In this paper, a magnetic permeability perturbation testing (MPPT) method is proposed to assess the internal axial cracks of small-diameter thick-walled steel pipes. The mechanism of the MPPT method and its corresponding probe and magnetizer are introduced, and its feasibility is verified through a series of simulations and experiments. Experiments conducted using different sizes of small-diameter thick-walled pipes show that this method offers good performance with respect to the detection of internal axial cracks. Additionally, both diameter and wall thickness significantly affect the MPPT signal. To a certain extent, a greater wall thickness or a smaller diameter brings about a weaker signal. This method does not benefit from the lift-off effect, nor is it limited by the skin effect, which has great practical value as a supplement to the evaluation of thick-walled steel pipes.
