NDT: Nondestructive Testing
Nondestructive testing (NDT) is an analysis discipline that evaluates the properties of a component or material without damaging or otherwise impacting its structural integrity. NDT examines a subject’s surface and/or sub-surface characteristics to determine its condition and detect flaws. Technicians may use NDT methods to look for seams, cracks, weld defects, laminations, or tears. Because NDT tests products in a way that leaves them intact, it is a cost-effective method of testing, naturally suited for:
  • Quality Control: verifying that products are within the standard geometric tolerances outline in their design specifications
  • First Article Inspection: validating production methods by searching for flaws and assessing material/component defects
  • Reverse Engineering: deriving a set of design specifications from precise measurements and material identification of an existing sample
  • Failure Analysis: determining the cause behind a material or component failure by assessing its failure mode
Computed Tomography in NDT
Computed tomography, or CT, is a form of NDT based on radiography. During a CT inspection, a technician places an object into a chamber outfitted with an emitter that emits X-rays from a multitude of different angles. The detector, mounted opposite, captures the energy that hits the subject as data. Next, a computer converts this data into thousands of cross-sectional images through a process called tomographic reconstruction. A technician can then compile that image set into a 3D model of the object.
CT’s versatility gives it an advantage over other forms of NDT, such as 3D scanning. 3D inspections cannot look beneath the surface of its test materials, whereas CT allows our technicians to locate imperfections below the surface and measure such features volumetrically. Computed tomography addresses more concerns with fewer tests than many comparable forms of NDT.
