摘要： A non-destructive inspection system that has particular application for inspecting a bore in a valve for defects. The system includes an inspection yoke having a ferromagnetic core, where a first coil is wound around the core in one direction and a second coil is wound around the core in an orthogonal direction so that orthogonal electromagnetic fields can be generated within the bore. A controller provides a current flow through the coils to generate the electromagnetic fields to detect defects in the bore.

摘要： A magnetic inspection station for tubular members and methods for operating the same have a longitudinal flaw detection assembly adapted to pass a circumferential magnetic field through a tubular member and a transverse flaw detection assembly adapted to pass a longitudinal magnetic field through the tubular member. The magnetic fields cause congregation of a ferromagnetic particles sprayed on the tubular member in a magnetic particle inspection fluid. The congregation of ferromagnetic particles indicates a flaw in the tubular member. The magnetic inspection station includes a clamping apparatus positioned closely adjacent to the magnetic inspection station and adapted to support the tubular member within the magnetic inspection station and exert a compensating force on the tubular member to resist the magnetic forces generated by the longitudinal flaw detection assembly and the transverse flaw detection assembly.

摘要： Using an image signal acquired by picking up a sample to be inspected by a color video camera, penetrant inspection and magnetic-particle inspection, which are non-destructive inspections, are carried out so that deficiency candidates, including a pseudo deficiency, are automatically detected and displayed on a screen. A real deficiency can be detected from the displayed deficiency candidates. As image data is stored in memory means, information of a deficiency can be repeatedly reproduced on the screen. In the penetrant inspection, the chromaticity at each position on an image is acquired, a deficiency candidate is extracted based on the chrominance, and the deficiency is distinguished from a pseudo deficiency based on the differential value of the chrominance. A polarization filter eliminates regular reflection originating from illumination in the penetrant inspection, and an ultraviolet-rays cutting filter prevents noise in the magnetic-particle inspection. Both inspections can be carried out with a single probe.

摘要： A method for inspecting the surface of a workpiece for the presence of flaws using a ferrofluid as a penetrant which is applied to the surface of the workpiece and then scanning the surface of the workpiece with electrical detection means placed adjacent to the surface for providing responses indicative of the presence of flaws in the surface of the workpiece. If desired, a magnetic field can be used to induce the flow of the ferrofluid into any flaws prior to inspection, and for post-inspection cleanup as well. By the use of a ferrofluid, the sensitivity of the electrical detection means, advantageously of the eddy current type, is enhanced in typical applications, and also allows the use of an eddy current probe to inspect workpieces made of nonconductive and/or nonferromagnetic materials.
