Abstract

A pioneering procedure for substance-to-substance joining of quartz glass is described. Diffusion welding was examined as a possible joining method. Welded components made of quartz glass are applied in high-temperature engineering for laser and optics applications. Quartz glass was joined without interlayers in order to maintain optical characteristics of the joining partners. Based on the principles of joint formation of pure SiO2-glass in the solid state, a joining technology, using diffusion welding, is described and the joints are analysed. Diffusion welding, realized at near-transformation temperature, results in an increase of polymerization and formation of an optical thin joining layer.
