Abstract

The data merging study of the two infrared thermography non-destructive techniques (NDT) on W7-X divertor targets allowed to improve significantly the sensitivity and reliability of detecting the fault size and location at the tile interfaces. This was possible due to the merging of infrared images. This original method of tile interfaces inspection has been validated using calibrated defects and then applied on fabricated components. The data merging method of infrared thermal images using the fuzzy logic method and Dempster-Shafer's model is presented in the paper.
