Abstract
A vacuum vessel, used for such as an X-ray image intensifier, is provided with a radiation-permeable window member prepared from titanium or alloys thereof. The window member is supported on a support frame of iron or alloys thereof by resistance welding. A method of manufacturing the vacuum vessel comprises the steps of: successively spot welding the periphery of the window member by resistive heating to a support frame made of iron or alloys thereof with a pressure of 40-200 kg/cm.sup.2 while interposing a metal foil insert member having a lower melting point than the transformation point of the window member between the window member and the support frame; and hermetically sealing the periphery of the window member in the support frame.
