Effective inspection of the flash welded joints with high capacity and inspection report
-
ultrasonic inspection of the weld joints along the rail section (including rail foot blades);
-
high efficiency (3-4 min. per 1 joint; up to 70 joints per shift);
-
108 inspection channels (00, 450, 580, 700)
-
automatic checking acoustic contact under all acoustic units;
-
system of prompts to operator by inspection stages;
-
recording GPS-coordinate of welded joint;
-
inspection protocol on each joint;
Modes of inspection weld joints:
-
availability of 5 acoustic units (on head and rail base point);
-
availability of 3 methods ultrasonic inspection (echo-, mirror, delta);
-
joint inspection for 4 stages: static – forward/back, scanning – forward/back;
-
providing results: defect on the rail image, A- and B – scan, parameters of setting flaw detector and detected defect;
-
analyzing results of scanning on B-scan with high and nominal sensitivity (-6 dB and 0 dB);
-
registration of the welded joint temperature;
-
detailed analysis of results on screen flaw detector or computer.
Display inspection results of weld joints:
-
Static mode: ultrasonic inspection of the joint from two sides by mirror method
-
Scanning: ultrasonic inspection of the joint sides by echo-method
-
Possibility of clarify defect by manual probes
