Two nondestructive methods usually are needed for flaw detection in railway rolling stock axles during production: one for subsurface flaw detection and second for surface breaking flaws detection. For first task the ultrasonic method satisfy all sensitivity and resolution without any competition. For second task the magnetic particle methods usually is applied. But this method has many disadvantages such as hard inspection operation automatization and low productivity. Due these features magnetic particle method is the main reason of limitation of automated system productivity in common. For new inspection system development the main task is the considerable increasing of inspection productivity for synchronizing of inspection procedures with production line productivity. Eddy current (EC) method for surface flaw detection is more perspective for automated inspection systems creation. The possibility to replace the magnetic particle method by application of new EC probes with multi-differential coil connection was determined in our earlier investigation. In view of the aforesaid the task of creating the new automated system with EC method as a partner of ultrasonic method was undertaken.
