Abstract

Surface roughness of parts is one of key parameters on bonding quality of transient liquid phase welding. In the paper, various preparation processes for parts of vacuum envelope of space traveling wave tube were employed. Differences among these preparation processes were studied. Parts of vacuum envelope were prepared by preferable processes. Perfect vacuum envelopes of space traveling wave tube were produced by transient liquid phase welding.
