When developing a new type of high vacuum aluminium valve, we were looking for a simple and reliable technology ensuring the firmness and vacuum tightness of various constituent parts. From the economical point of view, we see that besides welding and brazing, also the use of adhesives becomes interesting for making the joints. The compatibility of joined metal parts and the thermal properties of the materials must be taken into account. We have tested the adhesive strength, degassing and permeation through many non-demountable joints made with different glues. This contribution presents some typical constructions and the results of testing of the proposed joining technology.
