ETS2-77 is the mechanized scanning device for the manual testing by eddy-current method for presence of the surface cracks.
The UD3-71 ultrasonic flaw detector is designed for the testing of welded rail joints with a set of manual probes and USR-01 scanner.
The flaw detector is intended for defects detection in both rails along the running surface and rail cross-section, except for the rail base blades using flaw detection trolley during complete testing, and for the confirmatory testing of separate rail cross-sections and welded joints by means of manual probes.
UDS2-77 ultrasonic single rail flaw detector is a mechanized trolley intended for the inspection of one rail line.
The flaw detector utilizes a unique scanning scheme that allows testing the entire rail section, except for foot flanges, by pulse echo, echo-shadow and echo-image techniques.
