Safe operation of the machinery depends on quality of the individual machine parts. These are controlled by different non-destructive methods not only at the end of the production but also during it. In large quantity series production it is necessary to ensure the fastest control method possible. Shafts may bend during production due to the heat treatment and they need to be straightened by mechanical methods. Shafts straightening may cause cracks formation which is unacceptable from the point of view of the part operation. Therefore crack detection system QASS CiS.01 is used to reveal them on the basis of the magnitude of energy response. The results obtained from the detector were controlled using metallography and its function was successfully confirmed. It is not possible to determine relation between energy value and cracks length from carried out metallographic observation and values measured by the detector. |
