Abstract
Description
Die Erfindung betrifft ein Schutzgas zum Magnesium-Schweißen von Werkstoffen, insbesondere zum WIG- MIG-, MAG-, Laser- und Plasma-Schweißen von metallischen und nichtmetallischen Werkstoffen.The invention relates to a protective gas for magnesium welding of materials, in particular for TIG, MIG, MAG, laser and plasma welding of metallic and non-metallic materials.
Zum Magnesium-Schweißen von metallischen und nichtmetallischen Werkstoffen werden eine Vielzahl von Helium- und/oder Argon-Schutzgase mit oder ohne Zusätzen an Stickstoff, Wasserstoff, Kohlendioxid und Sauerstoff eingesetzt.For magnesium welding of metallic and non-metallic materials are a variety of helium and / or argon protective gases with or without additives nitrogen, hydrogen, carbon dioxide and oxygen.
Der Erfindung liegt die Aufgabe zugrunde, ein Schutzgas zum Magnesium-Schweißen von Werkstoffen, insbesondere zum WIG- MIG-, MAG-, Laser- und Plasma-Schweißen von metallischen und nichtmetallischen Werkstoffen, zu schaffen, mit dem eine Verbesserung der Leistungsfähigkeit beim Magnesium-Schweißen mit einer verbesserten Schweißqualität ermöglicht wird.The invention is based on the object Shielding gas for magnesium welding of materials, in particular for TIG, MIG, MAG, laser and plasma welding of metallic and non-metallic materials, to create with with an improvement in the performance of magnesium welding an improved welding quality is made possible.
Diese Aufgabe wird durch ein Schutzgas mit den Merkmalen von Anspruch 1 gelöst.This task is carried out by an inert gas solved with the features of claim 1.
Beim Magnesium-Schweißen von metallischen oder nichtmetallischen Werkstoffen werden durch den Einsatz des erfindungsgemäßen Argon-/Helium-Schutzgases mit einer Beimengung von bis zu 0,1 Vol.-% eines mindestens zweiatomigen Gases, wie beispielsweise Stickstoff und/oder Stickstoffoxid, folgende positiven Effekte erzielt:
- – wesentliche Verbesserung der Porenausbildung
- – deutliche Einbrandsteigerung
- – verbesserte Nahttiefe
- – reduzierte Nahtbreite
- – Leistungssteigerung
- – Prozesssicherheit
- - Significant improvement in pore formation
- - Significant increase in penetration
- - improved seam depth
- - reduced seam width
- - Performance increase
- - Process security
Es wurde gefunden, dass durch Einsatz eines Argon- und/oder Helium-Schutzgases mit einer Beimengung eines mindestens zweiatomigen Gases von bis zu 0,045 Vol.-% besonders gute Ergebnisse beim Magnesium-Schweißen von metallischen und nichtmetallischen Werkstoffen ermöglicht werden.It was found that through use an argon and / or helium protective gas with an admixture of at least a diatomic gas from to 0.045% by volume particularly good results when welding magnesium metallic and non-metallic materials.
Der im erfindungsgemäßen Argon- und/oder Helium-Schutzgas enthaltende, mindestens zweiatomige Gasbestandteil besteht besonders vorteilhaft aus Stickstoff und/oder Stickstoffoxid.The argon and / or helium protective gas containing at least diatomic gas component consists particularly advantageously of nitrogen and / or nitrogen oxide.
Der Mikrobestandteil im Schutzgas kann entsprechend dem jeweiligen Einsatzzweck problemlos angepasst werden und ermöglicht somit ein leistungsgesteigertes Magnesium-Schweißen von metallischen und nichtmetallischen Werkstoffen mit einer verbesserten Schweißqualität.The micro component in the protective gas can be easily adapted to the respective application be made possible thus a performance-enhanced magnesium welding of metallic and non-metallic Materials with an improved welding quality.
