Innovative Eddy Current Inspection on Lightweight Components

摘要

Due to the specification of a maximum weight savings in today's automotive industry more and more lightweight materials are used. Above all, aluminium finds wide application in this case, not only in the body area, but also in engine and transmission components. Due to the electromagnetic properties of aluminium, it is out-standing for testing using the eddy current method. Thus, multiple approaches revealed for testing complex aluminium components. In the present paper the potential of this non-destructive inspection technique in connection with classical image processing will be shown by two examples.
