The paper studies atoms evaporating from the 1370 aluminum alloy surface and the heat-affected zone during electron-beam welding. The proposed mathematical model is used to predict the spatial temperature distribution and mass losses of devices made of 1370 aluminum alloy depending on welding conditions. Experimental research concerns these processes. Theoretical calculations are compared with the experimental data. The alloy structure is investigated in the area of phase transformations. It is found that the vaporization intensity almost linearly depends on the beam current density and scanning speed. Experiments show that vaporization is an active process and can significantly affect the composition of the welding joint (mostly light elements evaporate) and, consequently, its mechanical properties.
