摘要：
Electron-beam welding features of metal-ceramic elements of membrane type are considered in this paper. Influences of welding speed and angle of entry of electron beam (in the lower position) on the formation of metal-ceramic membranes weld joints are shown. The macro and microstructure researches of weld joints were carried out. Electron beam welding mode parameters providing the high quality of the weld joint are determined. An appropriate weld joint is established to be formed at high welding speed and small angles of beam entry, herewith the welding on the descent promotes better removal of slag phase from weld metal.
