Title: TESTING OF AUTOMATICIZED SYSTEM FOR COMPLEX NON-DESTRUCTIVE STUDY OF METALLIC MATERIALS
Keywords: COMPLEX NON-DESTRUCTIVE TESTING

Abstract: A program to test automatized system for complex non-destructive testing of the structure, the physical and mechanical properties of samples and products from metallic materials is presented. The system consists of several modular devices that measure two non-destructive information parameters based on methods with different physical principles (magnetic, acoustic, thermoelectric, etc.). In the paper only two modular units-MULTITEST MC010 for testing ferromagnetic materials, based on the measurement of the magnetic noise voltage and magnetoacoustic emission and MULTITEST CD010 for testing of metallic materials based on measuring the speed and the attenuation coefficient of ultrasonic waves in the materials are presented. General methodology of the testing / measuring system, as well as methodology for calibration and metrological assurance of the equipment in operation of the system in a complex non-destructive testing has been developed. Conclusions are made on the reliability of the
