Automated MPI Test Fluid Quality Checks and Dye Penetrant Tam Panel Tests

摘要

Still today magnetic particle testing (MT) as well as dye penetrant testing (PT) belong to the most important and most sensitive inspection methods applied in the automotive and aircraft industries. Even though the principles have not changed during the last decades, the design of the machinery changed very much into production line integrated type of systems. Fig. 1 shows a typical operator driven MT system design from the seventies. In fig.2 we can see the same gentlemen today, standing in front of a modern production line integrated and machine vision aided MT shaft system. In this systems the human factor, that always effected the MT as well as the PT method has been reduced dramatically. These machines are principally set up as shown in fig. 3.
