Ultrasonic flaw detectors

Over few decades TOFD method is widely used for fast and reliable UT of welded joints. TOFD offers great accuracy for measuring the critical size of crack-like-defects. The accuracy of better than ±1mm can be obtained in a wide range of material thickness.

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.

The ОКО-22М-UT ultrasonic flaw detector is a standalone electronic unit and is intended for application in high-performance automated multi-channel NDT Systems, transportable systems (mechanized NDT systems) or for manual testing.

Available in several flaw detector models that are different in number of channels and in a volume of built-in functions for results processing.

UD3-71 flaw detector is an ultrasonic general-purpose flaw detector which is intended for:

  • manual non-destructive testing of products for detection of defects such as discontinuity and inhomogeneity of material in raw stock, finished items, in-process goods, welded, soldered, bolt, riveted and other joints;
  • measurement of defects depth and depth coordinates;
  • measurement of various items thickness at one-way access to them;
  • measurement of signals (reflected from defects) amplitudes ratio;
  • measurement of equivalent defects dimensions;
  • assessment of sound velocity in sundry materials.

UD4-76 universal ultrasonic flaw detector-tomograph with a large high-contrast TFT display is intended for products testing for detection of defects, such as discontinuity and inhomogeneity of materials, goods and in-process goods, welded joints, measurements of signals amplitude ratio from defects, of depth and their depth coordinates. Tomograph function enables to display and store testing results in the form of B-scans with reference to the scanning path. Flaw detector also solves the task of items thickness measurement at one-way access. Several operating modes for DGS diagrams are provided too, what makes it possible to define conveniently and quickly equivalent defects dimensions.
