Castings

Castings

The most common type of casting anomaly is porosity, whether individual pores or a shrinkage porosity condition. Digital x-ray imaging can identify the existence of porosity but cannot provide volumetric data about the condition. Computed tomography (CT) not only can provide a quantitative analysis of porosity in the casting, it can also be used to provide dimensions on both external and internal features.

  • Common uses: casting quality, metrology and first-article inspection, wall-thickness analysis, porosity analysis, foreign material.
  • Common products: turbine blade, wheels, engine components, chassis components, pistons, engine blocks and heads.
