Abstract: A system for inspecting a weld on a component where the weld has a plurality of cross-sections includes a camera disposed above the weld that optically senses a weld position. A projector disposed above the weld projects on to the component along a length of the weld position a primary scan path with a primary scan path start point and a primary scan path end point. An imaging probe scans the weld as the imaging probe moves from the primary scan path start point to the primary scan path end point to generate a plurality of 2D cross-sectional images of the weld corresponding to the cross-sections of the weld, the imaging probe having a position and skew angle that vary as the imaging probe moves. Each 2D cross-sectional image of the weld is optically encoded with a respective imaging probe position and a respective imaging probe skew angle.

Abstract: A method is provided for extending the service life of a used metallic compressor wheel having a damaged surface. The method generally comprises the steps of inspecting the used compressor wheel for material discontinuities such as fatigue cracks and, if fatigue cracks exceeding a predetermined length are not present, renewing the used compressor wheel such as by peening. The inspection process comprises conducting a non-destructive examination of the used compressor wheel to detect cracks larger than those which would fall generally within the compressive stress zone that is generated by peening.
