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.
