Patent ID: 8293059

Claim:
A method for joining components from glass based materials, comprising the steps of: providing a first component and at least a second component, both made from glasses that can be transformed by heat treatment into glass ceramics; providing a joining solder made of a glass that can be transformed by heat treatment into a glass ceramic; wherein said joining solder has a radiation absorption capacity higher than that of said first and second components to be joined; placing an intermediate layer of said joining solder between said first and second components, thereby forming a raw composite structure; irradiating said raw composite structure with radiation energy at least in a region wherein said joining solder extends between said first and second components until said joining solder softens sufficiently to bond together said first and second components and said joining solder for producing a composite structure; and thereafter ceramizing said composite structure, wherein said first and second components consist of LAS glasses and are pre-heated to a pre-heating temperature of at least 600 ° C., wherein said joining solder is heated by IR radiation within less than 1 minute to a bonding temperature of the joining solder in the range of 1100 ° C. to 1350 ° C., is held at said bonding temperature up to a maximum of 120 seconds to effect bonding of the composite structure, and is cooled thereafter.
