METHOD FOR PRODUCING AN INTEGRAL BOND BETWEEN COMPONENTS OF QUARTZ GLASS AND HEATING BURNER SUITED THEREFOR

摘要

A heating burner for making welding between components of quartz glass includes: a burner head in which at least one burner nozzle is formed; a burner head cooling system for temperature control of the burner head; and a supply line connected to the burner nozzle for fuel gas. The burner head includes a body of silver or silver-based alloy in order to modify the heating burner in such a way that the impurities in a weld line between the quartz glass components are avoided.
