Tomographic 1.1 – General Purpose Flaw Detector

It is the main application of the Tomographic UD4-ТМ flaw detector intended for testing of the base metal and welded joints (weld seams and weld adjacent zones) and implements functionality of the general purpose ultrasonic flaw detector.

Built-in function displaying the beam path makes it possible to determine flaw location in the tested object. It is very important when angle probes are used and allows visual evaluation of the flaw location depth and position.
Signal spectrum analysis and determination of the reflected signal frequency, calculation of the flaw equivalent area is one of the signal processing functions implemented in UD4-Т. Besides sweep of А-scan, software allows plotting of B-, С- and D-scans being important for testing of welds, as well as evaluation of flaw location. For plotting of these scans and determination of the PEP position, 2D ultrasonic scanner is used. For plotting of D-scan, TOFD (Time Of Flight Diffraction) method of ultrasonic testing is used. This method is suitable for detection of flaws like cracks and determination of their location depth. Testing results are recorded directly in the UD4-ТМ instrument, while data are transferred into computer by means of the service application “NDT operator AWS”.

Application “General Purpose Flaw Detector” allows the following:

• Detection of flaws like discontinuity and non-homogeneity in materials, semi-end products, end products and welded joints;
• Measurement of flaw depth and coordinates of their location;
• Determination of material thickness, propagation velocity and attenuation of ultrasonic waves (USW) in the material.
• Control of DAC curve in two modes: manual and automatic.
• Application of digital filtration to increase signal/noise ratio.
• Setting of PEP parameters like frequency, delay in wedge, angle, as well as their downloading directly from the PEP archive.
