Abstract
Known heating burners for producing a welded joint between components of quartz glass include a burner head in which at least one burner nozzle is formed, a burner-head cooling system for the temperature control of the burner head and a supply line connected to the burner nozzle for a fuel gas. Starting from this, to modify a heating burner in such a way that impurities in the weld seam between quartz-glass components to be connected are largely avoided, it is suggested that the burner head should include a base body of silver or of a silver-based alloy.

A heating burner for producing a welded joint between components of quartz glass, comprising:
- a burner head in which at least one burner nozzle is formed;
- said burner head comprises a base body of silver or of a silver-based alloy;
- a burner-head cooling system for the temperature control of the burner head;
- wherein in said burner-head cooling system two cooling water pipes for a cooling water supply and cooling water discharge are connected to each other via a fluidically continuous cooling channel;
- and
- a supply line connected to the burner nozzle for a fuel gas or a fuel gas mixture;
- wherein in said base body at least one burner nozzle is designed as a tubular insertion part of silver or of a silver-based alloy, that is inserted into a through hole in the base body.
