Abstract

The invention relates to a method and a device for detecting conformal eddy current of a special-shaped metal part, in particular to a device (10) for detecting electromagnetic eddy current of a special-shaped metal part with curved surfaces with different radians or a special-shaped metal part with curved surfaces with different radians, which is characterized by comprising a plurality of detection surfaces (11), the external eddy current detection sensor (12) is arranged on the detection surface, and at least one first detection surface (111) and at least one second detection surface (112) of the detection surface (11) are curved surfaces with different radians; approximate coil cambered surface sections are selected for detection according to different workpiece detection parts.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to the eddy current testing technology of metal parts with different shapes, and in particular to a conformal eddy current testing method and testing device for special-shaped metal parts. Background technique [0002] In modern industry, various metal parts emerge in endlessly, especially for some key parts, the indicators such as surface hardness and carburized layer depth are particularly important. For example, 100% of the production of an automobile part uses low-frequency eddy currents to evaluate the surface and near-surface state of its products to ensure product quality. Since its shape has multiple parts to be tested with different bumps, according to the conventional thinking, different profiling eddy current sensors must be configured. Although modern industrial robots are becoming more and more popular, frequent replacement of sensors, or the use of mul...
