INVESTGATE MATERIALS WITH NON-UNITFORM THICKNESS TO PROVIDE VIRTUAL WEDGE MANUFACTURING PARAMETERS DURING WELD DEFECT INSPECTION

Abstract

To evaluate metal samples with non-uniform thickness using radiography, we must comply with very strict standards. This is very laborious and costly, as well as requiring many arrangements. discrete experimental segments. The virtual wedge is cheap, easy to manufacture, highly portable and can be used for all different types of X-ray machines, and is one of the unique technical solutions that can solve most of the disadvantages. above techniques while still ensuring reliability in product quality assessment. The problem posed when using virtual wedges to investigate materials with heterogeneous thicknesses has solved the core problem of reducing the difference in blackness of the film, from which we can easily provide solutions. Virtual wedge method is suitable, wedge can change the irradiation time to the sample, higher mobility. Therefore, the research results can serve as a reference for other studies.
