Abstract
A method for determining the generation of a diffusion bond between two articles is disclosed. The two articles are sealed together to define a cavity therebetween. A vacuum is drawn in the cavity by means of an evacuation tube having a passageway. The passageway is then sealed and the articles are subjected to a temperature and pressure to diffusion bond the articles together. A successful diffusion bond can be determined if the evacuation tube sidewall is collapsed.
