Abstract: An apparatus and method for measuring broken spot weld artifacts has a framework for supporting a light and a plurality of cameras for acquiring controlled images of a specimen with minimal distortion and parallax. The framework holds the specimen flat and in a reproducible position, controlling movement while imaging. The image data is received in a computer programmed with image processing software capable of isolating and measuring the artifacts. A calibration standard is used to correct for aberrations.

Abstract: Methods for creating three-dimensional volume quality models of additively manufactured metal bodies are disclosed. In one embodiment, a method comprises additively manufacturing each metal layer of a metal body. One or more images of the first metal layer are obtained. The image(s) are processed to detect and map potential manufacturing defects in the first metal layer. A two-dimensional contour of the first metal layer is generated from the three-dimensional CAD model. The mapped defects are integrated into the two-dimensional contour. A first layer of a three-dimensional volume quality model of the metal body is created based on the integrated two-dimensional contour.
