Abstract

A protective gas mixture contains up to 80 vol.% helium and at least 10 vol.% hydrogen with a balance of argon and/or nitrogen.

Description

Die Erfindung betrifft ein Schutzgasgemisch für das Elektronenstrahlschweißen an Atmosphäre von metallischen Werkstoffen, insbesondere von Leichtmetallen, Stählen, Kupfer- und Kupferlegierungen.The invention relates to a protective gas mixture for electron beam welding in the atmosphere of metallic Materials, especially light metals, steels, copper and copper alloys.

Das bisher als Schutzgas beim Elektronenstrahlschweißen an Atmosphäre (Non Vacuum Electron Beam Welding = NV-EBW) von metallischen Werkstoffen, insbesondere von Leichtmetallen wie Aluminium zur Automobilfertigung, eingesetzte Helium steht nur in begrenzter Menge zur Verfügung.The previously used as a protective gas in electron beam welding in the atmosphere (Non Vacuum Electron Beam Welding (NV-EBW) of metallic materials, especially of light metals like aluminum for automobile production, The helium used is only available in limited quantities.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Schutzgas zum Elektronenstrahlschweißen an Atmosphäre von metallischen Werkstoffen zur Verfügung zu stellen, das eine kostengünstige und zudem qualitätsgerechte Werkstoffbearbeitung ermöglicht.The invention is therefore the object a protective gas for electron beam welding in the atmosphere of metallic Materials available to provide an inexpensive and also quality-appropriate Material processing enables.

Die Aufgabe wird erfindungsgemäß durch ein Schutzgas mit bis zu 80 Vol.-% Helium und mindestens 10 Vol.-% Wasserstoff, Rest Argon und/oder Stickstoff, gelöst.The object is achieved by a Shielding gas with up to 80 vol.% Helium and at least 10 vol.% Hydrogen, Balance argon and / or nitrogen, dissolved.

Das erfindungsgemäße Schutzgas für das Elektronenstrahlschweißen an Atmosphäre von metallischen Werkstoffen, insbesondere von Leichtmetallen, Stählen, Kupfer- und Kupferlegierungen ermöglicht eine kostengünstige und qualitätsgerechte Werkstoffbearbeitung.The shielding gas according to the invention for electron beam welding in the atmosphere of metallic Materials, especially light metals, steels, copper and copper alloys allows an inexpensive and quality-oriented material processing.
