Zusammenfassung:The urgency of experimental study of the formation of powerful electron beams in technological electron guns is substantiated. The design of a technological electron gun of ELA type is described and the possibility of adjusting the electrode gap for changing characteristics of the beam being formed is shown. A series of experiments on the melting of plates (of steel 30 and titanium alloy VT6Сh (Fe up to 0.4%; C up to 0.1%; Si up to 0.07%; V = 3.5-4.5%; N up to 0.05%; Ti = 87.62-90.63%; Al = 5.5-6.75%; O = 0.07-0.2%; H < 0.01%; other elements up to 0.3%) were carried out, during which the electrode gap was varied. Analysis of obtained macrosections of melting regions is made and conclusions about the effect of magnitude of the electrode gap on the shape and transverse dimensions of melting regions are drawn.
