Controlling the distribution of the current density of the electron beam in the process of electron-beam welding

摘要

The distribution of the energy density of the electron beam may differ from the normal law. The laws of distribution of the density of the energy of the electron beam using the information features - the entropy coefficient and the counter excess - may be related to the classes of the single- and two-modal exponential distributions and described by a single mathematical model. The information features of the distribution - the entropy coefficient and the counter excess - may be used for the control and stabilisation of the distribution of the density of the electron beam in electron-beam welding.
