Abstract: Digital ferromagnetic part inspection system and method use a magnetizer for magnetizing a ferromagnetic part to be inspected, wherein a defect in or near a surface of the ferromagnetic part causes an external magnetic field. A magnetic field sensing element is positioned near the ferromagnetic part for sensing the external magnetic field. An inspection module identifies the defect in or near the surface of the ferromagnetic part by interpreting data collected by the magnetic field sensing element in response to the magnetic field sensing element being placed near the ferromagnetic part.

Abstract: A method is disclosed for nondestructively examining airfoils for defects without removing them from the turbine machines of which they are a part. The method uses phased array ultrasound technology, which can be used with all types of airfoils. The angle of entry of the ultrasonic beam is varied by using phased array ultrasound technology. The phased array ultrasound allows an inspector to steer the ultrasonic beam toward an area of interest within the airfoil. The phased array allows an inspector to monitor multiple angles at once. So long as the scan angle does not exceed a calibrated range, an inspector can monitor an area of interest, no matter what the sound beam entry surface angle is. The ultrasonic beam is steered or phased to inspect different orientations with one scan. The method uses a phased array transducer that is a linear array probe that is comprised of a series of transducers.
