V1 Calibration Block is designed for verification of the ultrasonic flaw detectors used in the course of welded joints quality control by the UT method. It is DSTU 4002-2000 (ISO 2400, DIN 54120, B.S. 2704) compliant.
V2 Calibration Block is designed for verification of the ultrasonic flaw detectors used in the course of welded joints quality control by the UT method. It is DSTU 4002-2000 (ISO 7963, В.S.2704) compliant.
The Notched Calibration Block (having plane angular reflectors) is designed for setting up the scan duration and sensitivity of flaw detectors used with the single crystal angle beam probes during the testing of the plate and tube products.
KMT-176 M2 Set of the Ultrasonic Plane-Parallel Thickness Standards (KUSOT-180) is designed for certification and primary checking of the contact ultrasonic thickness gauges at the manufacturing site with the thickness range of 0.6-300 mm in steel and 1-300 mm in duraluminum, as well as for the periodic verification of these thickness gauges.
Step Calibration Block is used for tuning and setting of the ultrasonic thickness gauges.
AS2083 Calibration Block no. 2, IOW Type 2 Block is designed for the beam profile measurement and probe angle of the angle beam transducers (also called Beam Calibration Block). The Block is Australian Standard AS2083 and British Standard 2704* compliant.
SC Block is designed for shear ultrasonic waves sensitivity calibration. It is presented with the engineering plastic storage case. The SC Block is ASTM E164 and BRR/AWS standards compliant.
Ultrasonic non-destructive testing technique for flaw detection is based on propagation and reflection of high-frequency (0.5 to 24 MHz) UT waves in a test object (steel, plastic, composites, rubber, etc.), with their further processing and visualizing on a special-purpose NDT instrument (flaw detector).
This method is used to search for material defects (pores, hairlines, inclusions, inhomogeneities, etc.) and to control workmanship quality like welding, soldering, etc. Ultrasound examination is a mandatory procedure for manufacturing and operation of numerous critical parts, such as aircraft motor parts, main pipelines or rails.
Basic UT techniques are as follows:
