high-vacuum electron beam welding, high vacuum electron beam welding, high-vacuum welding
elektronkiirkeevituse alaliik – keevitus kõrgvaakumis, mis on saavutatud keevitamisega samas kambris, kus toimub elektronkiire moodustumine (vrd mittevaakumkeevitus, keskvaakumkeevitus), an electron-beam welding in which welding is performed in the same vacuum as electron beam generation (compare: nonvacuum welding, medium-vacuum welding)
