Ultrasonic inspection
in metallurgy
ULTRASOUND. The special sections of science and technique are devoted for resilient waves of high frequency. A human ear perceives spreading resilient waves in an environment with frequency to 16 000 vibrations are approximate in a second (Hertz); vibrations with more high frequency are an ultrasound (beyond the hearing). Usually an ultrasonic range is considered the frequency range from 20 000 to a few milliards hertz. Although scientists knew about existence of ultrasound a long ago, its practical use began comparatively recently in science, technique and industry. Now an ultrasound is widely used in different physical and technological methods. Through speed of sound spreading in an environment it is judged about its physical characteristics. Measurements of speed on ultrasonic frequencies are made to a high accuracy; hence adiabatic characteristics of fastrunning processes, values of specific heat of gases, resilient constants of solids are determined with very small errors, for example.
Flaw detection. Sounding with ultrasonic impulses is used and for researches of properties of different materials and production from them. Penetrate into the solids, such impulses are reflected from their bounds, and also from different foreign matters in the stratum of investigated medium, such as cavities, cracks and other, indicating their location. An ultrasound ??«check??» up the material, not causing destructions in it. Quality of massive steel forgings, aluminium blocks, railway rails, welded seam of machines are checked up by such non-destructive methods of control.
Flaw detection is presumptive name of non-destructive methods of control of materials (production); use for finding out violations of entirety or homogeneity of macrostructure, deviation of chemical composition and other aims. The most widespread are ultrasonic inspection, X-ray examination, scale inspection, luminescence flaw detection, capillary inspection, magnetic inspection , thermo-electric- and triboelectric flaw detection.
Electro-inductive fault detection (tokovikhrevaya fault detection), based on co-operation of the fields of vortical currents, excited the sensor of fault detector in the controlled detail, with the same sensor. Allows to automatize control of quality provoloki, pipes and etc at their production, to assort some materials on brands and other Ultrasonic soldering. Kavitatsiya, conditioned powerful ultrasonic waves in metallic fusions and destroying okisnuyu tape of aluminium, allows to conduct his soldering a tin solder without a gumboil. Wares from the metals soldered an ultrasound became the ordinary manufactured goods
Ultrasonic tooling. Energy of ultrasound is successfully used for machine treatment of details. A tip from littlecarbon steel, executed in accordance with the form of transversal section of the desired opening (or cavities), is fastened a hard solder by the end of the truncated metallic cone which an ultrasonic generator affects (thus amplitude of vibrations makes to 0,025 mm). In a gap between a steel tip and processed detail liquid suspenziya of abrasive is given (carbide of the coniferous forest). As an abrasive, but not steel chisel, comes forward in such method a cutting element, he allows to process very hard and fragile materials ???¬?? flowed, ceramics, alniko (Fe???¬??Ni???¬??Co???¬??Al-сплав), carbide of tungsten, hard-tempered steel; in addition, it is possible to process openings and cavities of difficult form an ultrasound, because relative motion of detail and cutting instrument can be not only rotatory.
