Abstract
Bei einem Verfahren zum Vorbereiten von Bauteilen aus oberflächlich oxidierendem Metall, insbesondere aus Aluminium, zum Schweißen oder Kleben, werden die Bauteile überhitztem Wasserdampf ausgesetzt.In a method for preparing components made of surface oxidizing metal, in particular aluminum, for welding or gluing, the components are exposed to superheated water vapor.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Vorbereiten eines Bauteils aus oberflächlich oxidierendem Metall, insbesondere aus Aluminium, zum Schweißen oder Kleben.The The invention relates to a method and apparatus for preparing a component of superficial oxidizing metal, in particular aluminum, for welding or Glue.
Aluminium findet in neuerer Zeit wegen seines geringen Gewichts zunehmend Verwendung in Kraftfahrzeugen, insbesondere in Fahrwerksteilen, bei denen, sofern sie gefedert sind, eine Gewichtsverminderung zusätzlich Komfort erhöhend wirkt.aluminum finds in recent times because of its low weight increasingly Use in motor vehicles, in particular in chassis parts, at those who are sprung, a weight reduction in addition comfort increasing acts.
Blanke Aluminiumoberflächen bilden an der Luft rasch eine Oxidschicht, die unmittelbar auf der Aluminiumoberfläche vorzugsweise aus Korund (α-Al2O3) besteht. Über dieser Sperrschicht entsteht je nach Lagerdauer, Umgebungsbedingungen usw. eine nicht genau definierte Deckschicht aus Aluminiumoxid, Aluminiumoxidhydroxid und/oder Aluminiumhydroxid.Bright aluminum surfaces rapidly form an oxide layer in the air, which is preferably composed of corundum (α-Al 2 O 3 ) directly on the aluminum surface. Depending on the duration of storage, environmental conditions, etc., a non-precisely defined covering layer of aluminum oxide, aluminum oxide hydroxide and / or aluminum hydroxide is formed over this barrier layer.
Für das Schweißen von Aluminium ist eine wohl definierte Oberfläche wichtig, um einwandfreie Schweißqualität sicherzustellen. Die vorstehend genannten undefinierten Deckschichten wirken sich störend auf die Schweiß- bzw. Nahtqualität hinsichtlich deren Festigkeit, Einschlüssen usw. aus.For welding Aluminum requires a well-defined surface to ensure perfect weld quality. The above-mentioned undefined layers have a disturbing effect the welding or seam quality in terms of their strength, inclusions, etc. from.
Um eine einwandfreie Schweißqualität zu erzielen, ist bekannt, mittels aufwändiger Verfahren, beispielsweise mittels Tauch-Druckumfluten, sowohl die Sperrschicht als auch die Deckschicht zu entfernen und die blanke Oberfläche zu passivieren. Dabei werden die zu verschweißenden Teile zunächst vorentfettet, dann nachentfettet, dann in mehreren Stufen fließgespült, anschließend passiviert, dann wieder in mehreren Stufen fließgespült und abschließend getrocknet. Um die Kosten zu reduzieren, wird beispielsweise lediglich eine Spritzreinigung durchgeführt, bei der die zu verschweißenden Bauteile vorentfettet werden, dann hauptentfettet werden, anschließend mehrfach gespült werden, in einem letzten Spülschritt mit entionisiertem Wasser gespült werden, und dann getrocknet werden. Diese Spritzreinigung führt jedoch zu nicht voll befriedigenden Ergebnissen.Around to achieve a perfect quality of welding is known, by means of elaborate Method, for example by immersion-pressure flooding, both the Barrier layer as well as the cover layer to remove and the bare one surface to passivate. The parts to be welded are first degreased, then degreased, then flow-rinsed in several stages, then passivated, then rinsed again in several stages and finally dried. To reduce costs, for example, only one Spray cleaning carried out, when the to be welded Components are pre-degreased, then degreased, then several times rinsed be, in a final rinse step be rinsed with deionized water, and then dried. However, this spray cleaning leads not completely satisfactory results.
Auch für das Verkleben von Bauteilen aus oberflächlich oxidierendem Metall mit anderen Bauteilen ist eine wohldefinierte Oberfläche vorteilhaft.Also for the Bonding of components of superficially oxidizing metal with other components, a well-defined surface is advantageous.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Vorbereiten eines Bauteils aus oberflächlich oxidierendem Metall, insbesondere aus Aluminium, zum Schweißen oder Kleben zu schaffen, bei dem zwischen dem Vorbereitungsschritt und dem Schweißen bzw. Kleben ein längerer Zeitraum liegen kann, ohne dass die Qualität der späteren Schweiß- oder Klebeverbindung nachteilig beeinflusst wird.Of the Invention is based on the object, a method for preparing a component of superficial oxidizing metal, in particular aluminum, for welding or To create bonding, between the preparation step and welding or sticking a longer one Period may be without the quality of the later welding or Adhesive is adversely affected.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved with the features of claim 1.
Überraschenderweise hat sich herausgestellt, dass bei der Bestrahlung mit überhitztem Wasserdampf, der aus entionisiertem Wasser erzeugt wird, die Oxidschicht des oberflächlich oxidierenden Metalls nicht abgetragen wird, sondern in einen wohl definierten, modifizierten Zustand übergeht, der definierte, einstellbare Schweißbedingungen ermöglicht. Diese Bedingungen bleiben auch bei Lagerung des behandelten Bauteils in schmutzfreier und trockener Atmosphäre während mehrerer Tage erhalten, da die Oberfläche durch die modifizierte Oxidschicht weiterhin passiviert ist. Überraschenderweise wird durch die Bestrahlung mit überhitztem Wasserdampf, der aus entionisiertem Wasser besteht, die Randzone bzw. die unregelmäßige Deckschicht aus Aluminiumoxid, -oxidhydroxid und -hydroxid homogenisiert, wodurch ein Schweißfachmann die für eine exakt reproduzierbare Schweißnaht erforderlichen Schweißparameter genau einstellen kann. Auch die Bedingungen für eine anschließende Verklebung sind wohl definiert.Surprisingly, it has been found that upon irradiation with superheated steam generated from deionized water, the oxide layer of the superficially oxidizing metal is not removed, but transitions to a well-defined, modified state that allows for defined, adjustable welding conditions. These conditions remain even during storage of the treated component in a dry and dry atmosphere for several days, since the surface is still passivated by the modified oxide layer. Surprisingly, the irradiation with superheated steam, which consists of deionized water, the edge zone or the irregular top layer of alumina, -oxidhydroxid and hydroxide homogenized, whereby a welding expert can set the exact required for a precisely reproducible weld welding parameters. The conditions for a subsequent bonding are well defined.
Die Unteransprüche 2 bis 6 sind auf vorteilhafte Durchführungsformen des erfindungsgemäßen Verfahrens gerichtet.The under claims 2 to 6 are advantageous embodiments of the method according to the invention directed.
Der Anspruch 7 kennzeichnet den grundsätzlichen Aufbau einer Vorrichtung zum Durchführen des erfindungsgemäßen Verfahrens.Of the Claim 7 indicates the basic structure of a device to perform the method according to the invention.
Die erfindungsgemäße Vorrichtung wird mit den Merkmalen des Anspruchs 8 in vorteilhafter Weise weitergebildet.The inventive device is further developed with the features of claim 8 in an advantageous manner.
Die Erfindung ist ganz allgemein zum Vorbereiten von Bauteilen zum Schweißen oder Kleben geeignet, die aus oberflächlich oxidierendem Metall bestehen. Besonders gut eignet sich die Erfindung für die Vorbereitung von Aluminiumbauteilen zum Schweißen.The Invention is generally for preparing components for welding or Adhesive suitable from the surface consist of oxidizing metal. The invention is particularly well suited for the Preparation of aluminum components for welding.
Wenn die Verbindung der Bauteile miteinander durch Verschweißen erfolgt, werden im Allgemeinen aus gleichem oder zumindest ähnlichem Metall bestehende, vorbereitete Bauteile miteinander verschweißt. Durch Verkleben können dagegen Bauteile aus unterschiedlichen Materialien miteinander verbunden werden, z.B. ein Bauteil aus Aluminium und ein Bauteil aus einem anderen Metall, Kunststoff, Verbundwerkstoff usw.If the connection of the components takes place by welding, are generally made of the same or at least similar Metal existing, prepared components welded together. By Gluing can In contrast, components made of different materials are connected to each other be, e.g. a component made of aluminum and a component of a other metal, plastic, composite etc.
