WELDING METHOD FOR JOINING COMPONENTS CONSISTING OF A HIGH-SILICA MATERIAL, AND APPARATUS FOR PERFORMING THE METHOD

摘要

In a known welding method for joining a first and at least one second component consisting of a high-silica material, an integral bond is formed between connection surfaces of the components, comprising the steps of clamping the components in a rotation and displacement means, moving the components towards each other by means of the rotation and displacement means in the direction of a central axis, simultaneously heating and softening the components in the area of the mutual connection surfaces by means of at least one heating burner, pressing the connection surfaces against each other to form a component assembly including a weld seam, and cooling the component assembly. Starting therefrom, to provide a method by means of which a solid weld seam can be produced in an exact and reproducible manner between quartz glass components to be joined, with impurities being largely avoided, it is suggested according to the invention that the components should be heated and softened in the area of the mutual connection surfaces within an enclosure enclosing an interior which is open at both sides.
