摘要： A method of inspecting a preselected area of an electrically conductive component to determine whether flaws are present. The method includes the steps of permanently mounting an eddy current element on the component over the preselected area and energizing the element to generate alternating magnetic fields proximate the component. An electrical signal generated by a secondary magnetic field formed proximate the component is detected using the element and the detected electrical signal is compared to a reference signal to determine whether the detected signal is different than the reference signal. Differences indicate the presence of a flaw in the component. Inspection apparatus for performing this method is also disclosed.

摘要： An omnidirectional eddy current probe includes a number of sense coils arranged in a stack having a principal axis. At least two of the sense coils are rotationally skewed about the principal axis relative to one another. The sense coils are operatively connected to each other and a drive coil is also positioned in the stack. An impulse through the drive coil induces a magnetic influx through a conducting material specimen having a surface, thereby generating eddy currents on the surface. Secondary magnetic field generated from the eddy currents produces corresponding signals in the sense coils, and the signals are then analyzed for the possibility of surface flaw in the conducting material.

摘要： Eddy current inspection of a contoured surface of a workpiece is performed by forming a backing piece of flexible, resiliently yieldable material with a contoured exterior surface conforming in shape to the workpiece contoured surface. The backing piece is preferably cast in place so as to conform to the workpiece contoured surface. A flexible eddy current array probe is attached to the contoured exterior surface of the backing piece such that the probe faces the contoured surface of the workpiece to be inspected when the backing piece is disposed adjacent to the workpiece. The backing piece is then expanded volumetrically by inserting at least one shim into a slot in the backing piece to provide sufficient contact pressure between the probe and the workpiece contoured surface to enable the inspection of the workpiece contoured surface to be performed.

摘要： An engineering component with a designed defect and use of an engineering component with a designed defect to evaluate a production component are disclosed. A test component having a known defect is manufactured. This known defect is a flaw that is intentionally included in the test component. The test component is then analyzed to obtain a test profile of the defect. In addition, the engineering component to be tested is analyzed to obtain a production profile. This production profile is compared with the test profile to determine whether the engineering component has a defect that corresponds to the known defect.

摘要： A method and system for ultrasonically inspecting turbine wheels and other disk-shaped articles having a central opening and multiple secondary openings radially spaced outward from the central opening. At least one ultrasonic transducer is placed in at least one of the secondary openings of the wheel. The transducer is configured and oriented to perform a pulse-echo diagnostic technique on the wheel by emitting ultrasonic signals that intersect radials of the wheel at angles of approximately ninety degrees to the radials. The ultrasonic signals intersect the radials at points so that a plurality of points are located on a plurality of radials. The points define a locus of points through the volume of the wheel between the central opening and the secondary opening, such that the volume is inspected for defects. The transducer receives ultrasonic signals that are reflected from one or more points when a defect is encountered.
