Information × Registration Number 0209U002365, 0107U000719 , R & D reports Title Development of equipment and technology of ultrasonic testing of the welding joints of the gas-turbine billows made by the electron-beam welding. popup.stage_title Head Gukov Uriy Danilovich, Registration Date 10-02-2009 Organization Ukrainian State Maritime University named after admiral Makarov popup.description2 The statistical analysis of presence of defects of electron-beam welds of units of gas turbines by results of the radiographic testing is executed. Frequency of emersion of different defects is shown at thickness of a welded material 3-5, 8-10 and 18-20 mm. Experimental researches of acoustical properties of welded joints of gas turbine shafts are executed. The possibility of holding of ultrasonic testing of these welded joints is shown. The optimum plan of the ultrasonic testing of welded joints of gas turbine shafts picked. Theoretical calculations of geometrical and acoustic parameters of transducers are executed. Experimental researches of designed transducers are executed. The analysis of an acoustic tract at the ultrasonic testing of electron-beam welds is executed. The experimental check of calculation data is executed Product Description popup.authors popup.nrat_date 2020-04-02 Close
