electron beam welding

The purpose of the work is to optimize the technological solution for the production of molybdenum tubular fittings of heat exchangers (TСs) that work at high temperatures and external mechanical load on calculated and practical modes of electron beam welding. The results of welding largely depend on the degree of contamination of the material, and the combined calculation of EBW parameters according to a set of existing methods does not give an unambiguous solution, but allows to outline the range of their acceptable values for further experimental clarification.

The article is devoted to the problem of defining the focal diameter of electron beam, formed by the
glow discharge electron guns, as well as the necessary pressure in the gun chamber for realising the
welding process. Taking into account, that glow discharge electron guns are widely used in industry
for welding of different metals, and that for providing the high quality of welding joints estimation
of energetic parameters in beam focus is very important, proposed methods are very important for
