Abstract

A special feature of non-destructive testing using X-ray computed tomography (XCT) of medium-sized aluminum alloy housing parts is that a tomogram is obtained simultaneously for two parts, CAD models of products were embedded in images for decoding tomographic images and sorting out control objects. Defect coordinates relative to the clean outline of the CAD model were used to determine their acceptability. Since X-ray computed tomography (XCT) is not feasible, porosity score assessment is selectively performed using traditional X-ray methods.
