The single electromagnetic method can be used to detect only one kind of material, the precision of defect quantification and dependability of defect detection are not high. The integration of multiple methods is an effective solution to this problem. On the basis of the previous research work, the pulsed excitation can provide wideband exciting frequency components and this excitation mode is introduced into the field of electromagnetic NDT technique.The key problems of the integration of multiple electromagnetic methods and integrative probe are studied in this paper, and the disadvantages of the single frequency excitation technique are overcomed. This researching achievement expected will extend and improve the research domain and level of Integration NDT technique, and also has an important theoretical meaning and a practical value for improving defect detecting ability of nondestructive testing.
