摘要

In the field of weld inspection, it is known that all the different types ofdefects cannot be detected by only one Ndt method. Ultrasonics andradiography are in most case complementary and are often used together onthe same specimen.In this paper and within the philosophy of complementarity betweenultrasonic and radiographic techniques, we try to build an image of theultrasonic controlled component, by an image processing method. And, Inorder to carry out this modelling a set of IIS reference radiograms weredigitised, and stored in Data banks.There are some theoretical developments of methods allowing solving 3Dreconstructionproblem. The algebraic reconstruction method, exactsolutions, image processing methods are the frequently used techniques. Oursolution is based on image processing models, and the software has tocombine data analysis feature of established 2D packages with advancedfacilities of data rotation, projection, slicing and 3D sizing tools.During the reconstruction process, the defect shape is correctly positionedwithin the welding geometry, and its map is generated in 2D and 3D imagemaking, according to the extracted profile of a similar defect fromradiograms.
