ABSTRACT
We present an industrial software system named Cerbero, the main goal of which is to take advantage of the superior capabilities of digital signal processing techniques. Cerbero collects the signals generated by the transducers (coils), digitalizes them, and performs temporal and spectral analysis in order to identify defects in the magnetic flux leakage (MFL) inspection of seamless steel pipes. Faulty operating conditions are also identified. A friendly graphic user interface allows the users to tune the system to inspect the products in agreement with the clients’ specifications. Currently, the system has been implemented in five units at the Siderca manufacturing plant, three of them aimed at the detection of longitudinal cracks, and two used for transverse cracks. In this paper we describe how the system was conceived, designed, and implemented. The system opens new challenges in signal processing applied to automated manufacturing that are also discussed. © 2000 American Institute of Physics.
