Abstract

Protective gas mixture contains hydrogen.

Description

Die Erfindung betrifft ein Schutzgas für das Elektronenstrahlschweißen an Atmosphäre von metallischen Werkstoffen, insbesondere von Leichtmetallen.The invention relates to a protective gas for electron beam welding in the atmosphere of metallic Materials, especially light metals.

Das bisher als Schutzgas beim Elektronenstrahlschweißen an Atmosphäre (Non Vacuum Electron Beam Welding = NV-EBW) von metallischen Werkstoffen, insbesondere von Leichtmetallen zur Automobilfertigung, eingesetzte, nur in begrenzter Menge zur Verfügung stehende und damit teure Helium bewirkt nur eine minimale Strahlaufweitung.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 used in automobile production, only available in limited quantities standing and therefore expensive helium causes only a minimal beam expansion.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Schutzgas für das 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 atmosphere of metallic materials to provide an inexpensive and also quality-appropriate Material processing enables.

Die Aufgabe wird erfindungsgemäß durch ein aus Wasserstoff bestehendes Schutzgas gelöst.The object is achieved by a Protective gas consisting of hydrogen dissolved.

Das erfindungsgemäße Schutzgas aus Wasserstoff für das Elektronenstrahlschweißen an Atmosphäre von metallischen Werkstoffen ermöglicht eine kostengünstige und qualitätsgerechte Werkstoffbearbeitung.The protective gas from hydrogen according to the invention for the electron beam welding in atmosphere of metallic materials enables a inexpensive and high quality Material processing.

Besonders vorteilhaft ist das erfindungsgemäße Wasserstoff-Schutzgas für das Elektronenstrahlschweißen an Atmosphäre von Leichtmetallen, insbesondere von Aluminium für die Automobilfertigung, einsetzbar.The hydrogen protective gas according to the invention is particularly advantageous for the electron beam welding in atmosphere of light metals, in particular aluminum, can be used for automobile production.
