Application of Thermal-Imaging Technology in Electron-Beam Metalworking (Review)
摘要
The ranges of changes in the main parameters of technological processes of electron-beam processing of materials, including melting, surface treatment, ablation, welding, and additive shaping, are determined; the parameters necessary for the selection of thermal-imaging equipment in order to monitor the area of impact of the electron beam on the processed material are highlighted. The classification of infrared cameras of various spectral ranges, including two- and multispectral systems, is given, and their fields of application and temperature ranges are highlighted. An overview of methods of thermal-imaging control of heating processes using an electron beam is performed, and the main trends in the use of infrared technology for solving problems of monitoring and controlling the parameters of electron-beam processing of materials are shown.
