Abstract
Data are given on commercial application of electron beam guns with plasma cathodes for welding zirconium and aluminium alloys. Design peculiarities of plasma sources of electrons and their advantages are considered. Many-year experience accumulated in the field of sealing the nuclear power station fuel elements by EBW shows a promising future of using the plasma-cathode electron guns for these purposes. The guns are simple in service and reliable in operation under complicated vacuum conditions.
Keywords: electron beam welding, plasma-cathode gun, fuel element
