Non-destructive testing

Installation of automated inspection of the welded rail joints AVTOCON-S

One-of-a-kind 


Designed for automated acceptance inspection of welded rail joints on railway plants


AVTOCON-S is installed on the rail plant (Saint-Petersburg)


Consist of:

  • carrying frame with scan device;

  • 8 ultrasonic wheel probes;

  • control device of pneumocylinders and linear scanners;

  • control PC;

  • display inspection results;

  • video cameras and additional devices.


Distinctive features of equipment:

  • increasing of testing capacity in three times (inspection time of one welded joint – not more 3 min);

  • minimization of human factor;

  • detailed inspection protocol of each welded joint;

  • 84-channel ultrasonic schemes;

  • three methods of ultrasonic inspection (echo-, mirror and mirror-shadow);

  • all benefits of the probes: qualitative acoustic contact, insensitivity to rough surface, long life expectancy, not required often settings.

  • detecting implicit defects of the welding;

  • display signals: mnemonic image of the rail with defect indication, B-scan, A-scan;

  • indication of parameters flaw detector setting  and detected defect;

  • measurement of rail straightness in welded joint area by electronic scale;

  • measurement of  hardness rail metal in welding area;

  • taking a photo of the welded joint surface;

  • data transfer to plant server;

  • technical solutions are patented by 4 patents.

 

Innovation technical solutions in AVICON-S are:

  • full automation of welded rail joints scanning;

  • application of new input methods ultrasonic oscillation in rail using ultrasonic probes;

  • complex diagnostic of quality welded rail joint (flaw detecting, geometry measuring, measuring of metal hardness);

  • taking a picture of number and surface state of welded joint;

  • registration of the parameters and inspection process with detailed protocol;

  • possibility to  transfer diagnostic information to central server for making rail electronic passport.
