SIMULATION OF EVAPORATION PROCESSES AT "MULTI-KEYHOLE" TECHNOLOGY IN ELECTRON BEAMWELDING
The paper describes a numerical model of the processes of evaporation, condensa- tion and diffusion of alloying elements AMg-6 in electron beam welding with at “multi- keyhole" technology in electron beam welding (EBW), which allows to predict the chemical composition of the weld. To verify the developed model, the experiment was conducted with the performance of passes on the different modes at“multi-keyhole " technology in EBW. Ma- crosection investigated the cross-sectional passages using X-ray fluorescence analysis, the results of which coincide with the calculated values.
