A nondestructive inspection of the fuel element weld seam by a panoramic tomography method

摘要

A summary of an automatic X-ray tomography station for weld connections control of rod fuel elements is presented in this paper. It also gives a description of the algorithms for obtaining multilayer panoramic tomograms. The investigation results of the automatic defect like pores location and measurement are stated here. The proposed decisions allow to carry out a total seam control during one minute, to locate and measure in automatic mode the pores with dimensions of 100 micrometers and more with an error of no more than 15%.
