The importance of non-destructive testing methods in ensuring the safety of
The most important problem of Railways is ensuring transport safety and environmental safety Features of the operation of Railways in Latvia and other Baltic countries : excessive terms of use of track structures, rolling stock, electric traction complex; insufficiently high technical level of operation of track structures, rolling stock, electric traction complex; difficult climatic conditions for diagnostics of technical devices during their operation; growth in transit traffic volumes on the international transport corridor East-West; increasing the weight of trains and the speed of movement. Prevention of accidents and man-made disasters in real conditions is associated with the need for monitoring, as well as diagnostics of the technical condition of railway transport devices by non-destructive testing methods

Of the methods of magnetic type of control in railway transport, the most widespread are the following: magnetic Powder (used everywhere); magnetic powder control is subjected to the following objects of rolling stock: parts of shock-traction and braking equipment, bogie frames of various models both assembled and by elements, axles of wheel pairs of all types both assembled and in a free state, disks, comb and spokes of locomotive wheels, etc. Fluxgate method of control – used in railcar and locomotive sector for the control of parts and components of locomotives and wagons. Induction method is used in the road economy is to control the rails.

On railway transport, the following components are checked by eddy current control : - all-rolled wheels of the wheel pair; - elements of the axle box unit; - elements of bogies of various models and axle bearings; - brake transmission devices, automatic coupling device. Eddy current monitoring is widely used to detect hidden metal and metal-containing objects. The method detects all types of metals and even objects with a very low metal content eddy Current methods have two main limitations –- they are used only for the control of electrically conductive products – they have a small depth of control associated with the peculiarities of penetration of electromagnetic waves into the object of control.
