Universal Ultrasonic Flaw Detector (TOFD version) – UD4-76

UD4-76 Universal Ultrasonic Flaw Detector - TOFD version

 

UD4-76 flaw detector – ultrasonic laboratory within dimensions of manual flaw detector

Analyzing the trends of NDT equipment development and our customers’ comments, “PROMPRYLAD” LLC specialists concluded that it is necessary to design a new ultrasonic flaw detector with extended functionality. Tomograph functions – B-scans read-out with scanning path timing, construction and operation with orthogonal views of B-scans – became main add-ons. These options allow an operator to get the information on dimensions and distribution of defects in the testing object in real time. So, there will be no need to calculate mentally and draw defectograms any more. Mutual bracing of detected flaws will be visually displayed on the orthogonal views of B-scan. Execution of measurements by radio-frequency B-scans will make it possible to get the information not only about conditional, but also about actual (in case of TOFD techniques applying) dimensions of defects. Flaw detector provides convenient corrosion mapping, too. The tools for operation with signal spectrum and many other functions have been added as well.

Plenty of functions may create an impression that flaw detector is difficult to master. However, that’s not true. Design engineers have taken a set of measures simplifying flaw detector operation. Firstly, this is a considered structure of tree-coded menus where all setups of the instrument are grouped in intuitive order. Moreover, there are two menu modes – “User” and “Expert”. In the first mode only basic setups of the instrument are presented in the menu, in the second mode – the entire spectrum of functions of flaw detector-tomograph is available.

For the reader’s convenience the description of instrument capacities is made in the following way: at the beginning there is a list of functions and technical specifications of flaw detector, and then, the most interesting ones of them are described in detail.

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.

UD4-76 universal ultrasonic flaw detector is adapted and totally meets the requirements of regulatory documentation valid in various industrial sectors, such as nuclear power engineering, metal production, pipe industry, rail transportation etc.

For carrying out the testing of different parts, an individual approach is required for solving each separate task.

1. Special operating modes performed on the basis of the instrument software package and adapted to the customer’s needs (among them there are: “Peak” mode, “Reflections marking” mode, automatic algorithms of probe calibration, modes of automatic DGS-diagrams and TCG-curves plotting, data storage in the form of RF B-scan, rendering of “corrosion map” (“thicknesses map”) and other);
2. Flaw detector ergonomics when working with the object (large high-contrast TFT-display, small instrument weight, convenient menu, presence of automatic sound and light alarm of defects at three levels: search, registration, acceptance);
3. Individual delivery set which includes the set of ultrasonic probes adapted to the testing of a certain range of welded joints and other ultrasonic testing objects.
