Calculation of weld parameters and thermal efficiency in electron beam welding

Abstract Using the model of quasi-steady thermal distribution in a solid sample, generated by a linear heat source, moving at constant welding velocity, values of the weld depth at a given weld width are calculated and compared with the experimental data. A discussion for thermal efficiency and an analysis concerning the correlation between the weld depth and weld width and the process parameters are given. The results show that the steady operating, moving linear heat source can be assumed as an approximation in the simulation of electron beam welding with a deep penetrating beam.
