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.

The UDS2-77 single rail flaw detector is capable of testing only one of the rails at a time for defects detection along the running surface and entire rail section excluding the rail foot flanges and also is intended for conformity testing of separate rail sections and welds using manual probes.

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.
