| Abstract [eng] |
The first chapter reviews the track inspection and verification work planning, preparation and Thermite welding joints. Examined track chemical composition and mechanical properties, Aluminothermic interface composition and structure. Done hand flaw detectors RDM - 3 RDM - 33 and eddy current flaw detectors 7505 analysis. Reviewed Aluminothermic splicing defect types and detection methods. The second chapter reviewed Aluminothermic defektroskopo RDM - 33 methodology. Preparing Aluminothermic splice inspection with flaw detectors. Procedure meanwhile was changed detector input 0 angles, 45, 70. The third chapter studied the problem of complying with artificial defects in Thermite junction using manual controls and continuous flaw detectors RDM - 22, RDM - 23, RDM - 33 and eddy current flaw detectors 7505th. It was determined that Aluminothermic welded rail joints defects need to use a wider range of inverters with wider searching the corners. |
