摘要

Purpose: The need for reliability of industrial structures, machines and other equipment requires more accurate testing of structural materials, especially ferromagnetic materials. Therefore, it is important to improve existing or develop new, more accurate methods and devices for non-destructive testing.Design/methodology/approach: Non-destructive testing of ferromagnetic materials is carried out by surveying a local magnetic field or determining the section magnetic resistance of a material using the proposed new type of sensor as the hand inductive element on a toroidal core with additional magnetic cores.Findings: This sensor has a simple design and high response characteristic, which has been confirmed experimentally. Such a sensor can be used for testing welded joints by the proposed method, which is based on measuring the magnetic resistance of the welding area.Research limitations/implications: Analytical physical processes research that occurred in the magnetic core material of the sensor coil core, used as a sensitive element, is complicated by the nonlinearity of the magnetization curve of the material of the core of the sensitive element and the lack of a single analytical relationship to fully describe the magnetization process of ferromagnetic materials of inductive elements. Therefore, each copy of the sensor will be an individual graduation. Practical implications: The proposed version of the hand inductive sensor allows to perform non-destructive testing during the operation of ferromagnetic structures and without special requirements to external conditions with low costs and the possibility of computer processing of data.Originality/value: The use of the nonlinearity zone of the magnetization curve of the inductive element core material made it possible to obtain a variant of a magnetic sensor that is close in sensitivity to fluxgate and, at the same time, is much simpler in design using non-deficient materials. The use of a ferrite core with low saturation induction requires a small circuit supply voltage, but a generator power reserve. The proposed hand inductive sensor is sensitive to the presence of extraneous ferromagnetic objects, and responds only to a magnetic field. The high magnetic resistance of the inductive sensor allows it to be used on uneven and dirty surfaces. High sensitivity allows to detect small deviations of the magnetic fields of dispersion of a welded joint with their comparison along the entire joint length. All of this gave new opportunities for more accurate non-destructive testing of structural elements and materials.
