Abstract: “In this paper the simulation of electron beam welding of thin 316L stainless steel thin plates by a moving linear heat source is considered. Regression models for the molten pool geometry characteristics, depending on the electron beam power and the welding velocity are estimated. The thermal histories and the cooling rates defining the microstructure and the distribution of the mechanical properties of the welded samples are also estimated. The influences of the initial temperature T0 and the welded sample thickness on the temperature distributions are demonstrated.”
