Multichannel flaw detector MIG-UKSM for ultrasonic inspection of welded joints

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:


  1. Static mode: ultrasonic inspection of the joint from two sides by mirror method

  2. Scanning: ultrasonic inspection of the joint sides by echo-method

  3. Possibility of clarify defect by manual probes
