With the development and application of PCI technology and TFM technology in the past years,the data processing methods corresponding to FMC and PWI have become increasingly rich,gradually transforming from optimizing qualitative auxiliary tools to a complete set of advanced technologies that can be used for practical examination.This paper conducted relevant research on the combination of PCI technique and TFM technique.By comparing different combination of these two methods,it was concluded that the examination efficiency and imaging quality of titanium weld seam can be optimized by adding the opposing tandem PWI/FMC-PCI technique to PWI-TFM technique.
