Electron beam scan pattern for electron beam welding and heat treatment should ensure the temperature-time parameters of structural-phase transformations in the metal processing zone: degree of heating, nature of heat distribution, cooling and heating rate. Thermal cycles can be regulated by controlling the thermal power of the electron beam, its focusing and space-time position. A multi-purpose computer program was developed for scan pattern design, which allows realization of the scan pattern with an arbitrary (set by the technologist) resulting distribution of electron beam power density by the points of its dwelling in the zone of impact on the metal for welding and heat treatment of the product. As a result, variations of currents of the defl ecting coils and focal lens synchronized with the scan pattern, are calculated. 10 Ref., 8 Fig.
Keywords: electron beam technologies, beam power density, electron beam scan pattern, heat treatment, graphic computer design of the scan.
