EDC RAIL 5065 Rail Testing Eddy-Current Machine

 

EDC RAIL 5065 Eddy-Current Testing Machine is designed for automated non-destructive testing of railway rails by eddy-current method in the course of their manufacturing. The presence of surface defects such as outer surface cracks of the rail heads, flutings and railway rails base of R50, R65, R65K, 60E1, UIC60 types is tested according to GOST R 51685-2013, DIN EN 13674-1-2017.


Optionally, the Machine can include some equipment for testing of the side edges and rail head flutings according to the requirements of DIN EN 13674-1-2017.

The Machine consists of structurally stand-alone parts installed in the manufacturing process line:

  • The eddy-current rail head and rail base inspection module (hereinafter in the text - Eddy-Current Module №1);

Advantages and main functions of the system:

  • Eddy-current module No. 1 provides for testing of the rail base except for 5 mm near-edge parts, testing of the rails head in the area of running surface within ± 24 mm from the rail vertical axis.

    Eddy-current module No. 1 provides for testing of the rail base except

  • Eddy-Current Module No. 2 provides for testing of the rails head in the area with upper flutings (the testing area starts at a distance of ± 24 mm from the rail vertical axis) and side surfaces (the testing area starts at the point of the rail head upper radii interface with the side edge; the testing area finishes at the interface point of the rail head side edge with the lower radius).
  • Eddy-Current Module No. 2 provides for testing of the rails head in the area with upper flutings

  • The Machine, fully assembled and equipped, covers 100% of the rails surface testing area according to DIN EN 13674-1-2017, except for the uncontrolled areas at the ends: uncontrolled area at the front end of the rail (in the direction of rail travel) is 200 mm and uncontrolled area at the rear end of the rail (in the direction of rail travel) is 100 mm.
  • The rails of type R50, R65, R65K manufactured in accordance with the requirements of GOST R 51685-2013 and rails of 60E1, UIC60 type manufactured in accordance with DIN EN 13674-1-2017 are subject for testing with the Machine.
  • The length of the tested rails is 25 m.
  • The Machine displays defective rail cross-sections in real-time display mode, with the information displayed on the monitor, and paint marking of defective rail cross-sections is performed in real-time display mode. The paint marking accuracy is not worse than ± 100 mm.
