| Abstract Scope |
Glass-to-metal seals are a critical component used in technologies that require electrical signals to be transmitted into or out of vacuum-tight or extreme-temperature environments. A typical glass to metal sealing process requires precisely formed metal and glass components, which must then be carefully bonded in a high temperature furnace. These processes require specialty tooling and are time consuming. In this project, we seek to create a quick, flexible glass-to-metal sealing technique by using a laser-based glass forming process. In our study, we identify four critical process parameters; namely, volume of inserted glass, speed of glass insertion, laser power, and heating time before glass insertion. We then create a set of seals with a broad set of process parameter values. Finally, to determine the most effective set of process parameters, we evaluate the manufactured seals for strength, stress distribution, and quality of glass-to-metal interface. |
