Digital Radiography and X-ray Computed Tomography Slice Inspection of an Aluminum Truss Section

Abstract

A sectioned specimen that had been removed from a larger aluminum truss structure, which was designed to sustain mechanical load while minimizing its weight and structural complexity, was provided. The specimen was inspected by digital radiography and slice x-ray computed tomography to determine if the vertices, or nodes, exhibited any porosity or shrinkage cavities and, secondly, if any other casting defects were present.
