Surface crack test

The eddy current method

The eddy current method to DIN EN ISO 15548 is a non-destructive and contactless method for testing materials. It detects material defects, such as cracks, laps, pores or point imperfections on the surface of the material. No additional media such as coupling liquids are required. Components with sensitive surfaces can be tested without a problem.

 

Material crack test

The surface of the specimen to be tested is scanned by one or multiple eddy current probes without any contact. The specimen, set in rotation by a mechanism, is scanned by a fixed probe. Alternatively, a rotating probe scans the test material at rest. Either one test trace can be recorded over the circumference with one probe or multiple test paths traces can be recorded by probes arranged in parallel. The choice of probe depends on the component geometry, cycle time and defect specification. Upon customer request, the probes can be individually adapted to the component contour.

The contactless eddy current crack detection system can be integrated into complex production processes. The test results can be documented online and data for the documentation simply processed. In addition, the components are automatically sorted into good and bad parts after the test.
