Abstract
Description
Die Erfindung betrifft ein Verfahren zum Fügen von Stahlsubstraten in einem Fügebereich, bei welchem mindestens ein Stahlsubstrat eine Oberflächenbeschichtung aufweist.The The invention relates to a method for joining steel substrates in a joint area in which at least one steel substrate has a surface coating.
Oberflächenveredelte Stahlsubstrate, insbesondere Bleche, Platinen oder Bänder werden im Kraftfahrzeugbau in vermehrtem Umfang eingesetzt. Die Stahlsubstrate sind ein- oder beidseitig mit einer anorganischen oder organischen Oberflächenbeschichtung versehen, welche beispielsweise eine deutliche Verbesserung der Korrosionsbeständigkeit bewirken. Als anorganische, insbesondere metallische Korrosionsschutzschicht ist beispielsweise eine Aluminium-Silizium-Oberflächenbeschichtung von Stahl- oder Stahllegierungssubstraten bekannt. Allerdings dringen Teile der Oberflächenbeschichtung beim Schweißen in den Bereich der Schweißnaht ein, so dass das Schweißgefüge negativ beeinflusst wird. So bilden Aluminium, Silizium und Eisen metallurgische Phasen, wenn Aluminium und Silizium beim Schweißen in die Schweißnaht hineingetragen wird. Es ist daher wünschenswert die Oberflächenbeschichtung vor dem Verschweißen zumindest in dem Fügebereich zu entfernen.Coated Steel substrates, in particular sheets, blanks or strips are used in motor vehicle construction to an increased extent. The Steel substrates are one or both sides with an inorganic one or organic surface coating which For example, cause a significant improvement in corrosion resistance. As an inorganic, in particular metallic corrosion protection layer is, for example, an aluminum-silicon surface coating of steel or steel alloy substrates. However, penetrate Parts of the surface coating during welding in the area of the weld, so that the welded structure is negatively influenced. So form aluminum, silicon and iron metallurgical phases, when aluminum and silicon during welding is carried into the weld. It is therefore desirable the surface coating before welding at least in the joint area to remove.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde ein Verfahren zum Fügen von Stahlsubstraten zur Verfügung zu stellen, mit welchem mit geringem apparativen und zeitlichen Aufwand auch oberflächenbeschichtete Stahlsubstrate mit hoher Fügenahtqualität miteinander verbunden werden können.Of these, Based on the present invention, the object is based a method for joining steel substrates available to provide, with which with little equipment and time also surface-coated steel substrates with high joint seam quality can be connected to each other.
Die oben aufgezeigte Aufgabe wird gemäß einer ersten Lehre der vorliegenden Erfindung dadurch gelöst, dass die Oberflächenbeschichtung des mindestens einen Stahlsubstrats unter Verwendung von Mitteln zur Erzeugung eines hochfrequenten elektromagnetischen Feldes zumindest im Fügebereich entfernt wird und beide Stahlsubstrate im Fügebereich miteinander verbunden werden.The The object shown above is according to a first Teaching the present invention achieved in that the Surface coating of the at least one steel substrate using means for generating a high-frequency electromagnetic Field is removed at least in the joining area and both Steel substrates are joined together in the joining area.
Es hat sich überraschenderweise gezeigt, dass die Verwendung hochfrequenter, elektromagnetischer Felder zur Entfernung von Oberflächenbeschichtungen eines Stahlsubstrats besonders vorteilhaft ist. Über das hochfrequente elektromagnetische Wechselfeld werden nämlich im Wesentlichen nur die Oberflächen nahen Bereiche des Stahlsubstrats, also vor allem die Oberflächenbeschichtung erhitzt, so dass diese erweicht und aufgrund des elektromagnetischen Feldes eine Lorentz-Kraft auf die dann fließfähige Beschichtung wirkt, so dass diese aus dem Fügebereich getrieben wird. Im Ergebnis sind die Fügebereiche, sofern sie mit einer Oberflächenbeschichtung versehen sind, durch die Verwendung des elektromagnetischen Wechselfeldes nunmehr frei von der Oberflächenbeschichtung und können einwandfrei miteinander gefügt bzw. verschweißt werden. Die anschließend hergestellte Füge- bzw. Schweißnaht umfasst nur Materialien der Stahlsubstrate, so dass Aushärtungen, Versprödungen und metallische Kerben durch Bestandteile aus der Oberflächenbeschichtung verhindert werden.It Surprisingly, it has been shown that the use high-frequency electromagnetic fields to remove surface coatings a steel substrate is particularly advantageous. About the namely high frequency electromagnetic alternating field essentially only the surfaces near areas of the Steel substrates, so especially the surface coating heated so that it softens and due to the electromagnetic Feldes a Lorentz force on the then flowable Coating acts so that these are driven out of the joint area becomes. As a result, the joining areas, if they are with a surface coating are provided by the Use of the alternating electromagnetic field now free of the surface coating and can be flawless be joined or welded together. The subsequently produced joining or welding seam includes only materials of steel substrates, so that curing, Embrittlement and metallic scores due to components be prevented from the surface coating.
Gemäß einer ersten vorteilhaften Ausführungsform des erfindungsgemäßen Verfahrens wird als Mittel zur Erzeugung eines hochfrequenten elektromagnetischen Feldes mindestens ein Induktionsleiter verwendet, mit welchem im Fügebereich des Stahlsubstrats hochfrequente, oberflächennahe Wechselströme induziert werden. Der Induktionsleiter wird hierzu dicht über dem beschichteten Fügebereich des Stahlsubstrats angeordnet, so dass im Fügebereich ein möglichst hoher, oberflächennaher hochfrequenter Strom induziert wird. Da nur geschlossene Rückflussstrombahnen induziert werden, können aber auch Bereiche des Stahlsubstrats, über welche kein Induktionsleiter angeordnet ist, durchflossen und erwärmt werden.According to one first advantageous embodiment of the invention Method is used as a means of generating a high-frequency electromagnetic Feldes at least one induction conductor used with which in the Joining of the steel substrate high-frequency, near-surface AC currents be induced. The induction conductor is this tight over arranged the coated joining region of the steel substrate, so that in the joint area as high as possible, near-surface high-frequency Current is induced. Because only closed return flow paths but can also be areas of the steel substrate, over which no induction conductor is arranged, flows through and heated become.
Vorzugsweise werden die Stahlsubstrate unter Verwendung eines induktiven Hochfrequenzschweißens, Widerstandsschweißens, Lichtbogen- oder Laserstrahlschweißen im Fügebereich verschweißt. Der Aufwand zur Erzeugung der Schweißnaht wird besonders gering, wenn die Mittel zur Erzeugung des hochfrequenten elektromagnetischen Feldes zur Entfernung der Oberflächenbeschichtung gleichzeitig zum Hochfrequenzschweißen verwendet werden. Es kann aber auch mindestens ein weiterer Induktionsleiter vorgesehen sein, um im Bereich einer Schweißzone die Bleche auf Schweißtemperatur zu erhitzen. Die anderen konventionellen Schweißverfahren wie Widerstandsschweißen, Lichtbogen- und Laserstrahlschweißen ermöglichen ebenso in Kombination mit der erfindungsgemäßen Entfernung der Oberflächenbeschichtung ein einfaches und prozesssicheres Fügeverfahren der Stahlsubstrate.Preferably, the steel substrates are welded using inductive high frequency welding, resistance welding, arc or laser beam welding in the joint area. The cost of producing the weld is particularly low when the means for generating the high-frequency electromagnetic field to remove the surface coating are used simultaneously for high-frequency welding. But it can also be provided at least one further induction conductor to the sheets in the region of a welding zone to welding temperature to heat. The other conventional welding methods such as resistance welding, arc welding and laser beam welding also, in combination with the removal of the surface coating according to the invention, enable a simple and process-reliable joining method of the steel substrates.
Besonders einfach gelingt das Fügen von band oder blechförmigen Stahlsubstraten, insbesondere unterschiedlicher Dicken und/oder Güten, also beispielsweise von „Tailored Blanks" oder „Tailored Strips", dadurch, dass der Fügebereich eine Fügekante bzw. eine Fügefläche mindestens eines Stahlsubstrats ist und nur an der Fügekante und/oder -fläche des Stahlsubstrats durch das induzierte elektromagnetische Feld die Oberflächenbeschichtung entfernt wird.Especially The joining of band or sheet-shaped is easy Steel substrates, in particular different thicknesses and / or Grades, for example of "tailored blanks" or "Tailored Strips", in that the joining area a joining edge or a joining surface at least a steel substrate and only at the joining edge and / or surface of the steel substrate by the induced electromagnetic Field the surface coating is removed.
Der zur Beseitigung der Oberflächenbeschichtung verwendete Induktionsleiter kann bügelförmig ausgebildet sein und so angeordnet werden, dass die Fügekante die Schenkel des bügelförmigen Induktionsleiters schließt. Da nur geschlossene Strombahnen induziert werden, werden bei dieser Anordnung aufgrund des "Skin-Effekts" die Rückflussstrombahnen der induzierten Ströme auf die Fügekanten/-flächen der Stahlsubstrate konzentriert. Hierdurch wird in den Kanten- bzw. Fügebereichen die Oberflächenbeschichtung beseitigt.Of the used to remove the surface coating Induction conductor can be formed bow-shaped be and be arranged so that the joining edge of the legs of the bow-shaped induction conductor closes. Since only closed current paths are induced, in this arrangement due to the "skin effect" the return flow paths of the induced currents on the joining edges / surfaces concentrated steel substrates. This is in the edge or Joining areas eliminates the surface coating.
Gemäß einer weiteren Ausführungsform des erfindungsgemäßen Verfahrens werden durch auf beiden Seiten der Stahlsubstrate angeordnete Mittel zur Erzeugung eines hochfrequenten elektromagnetischen Feldes die Oberflächenbeschichtung beidseitig im Bereich der Fügekanten entfernt. Hierdurch wird ermöglicht, die Stahlsubstrate später in einem I-Stoß miteinander zu verbinden, ohne dass die Qualität der Schweißnaht durch vorhandene Anteile der Oberflächenbeschichtung in der Schweißnaht verringert wird.According to one another embodiment of the invention Process are arranged by on both sides of the steel substrates Means for generating a high frequency electromagnetic field the surface coating on both sides in the area of the joint edges away. This allows the steel substrates later to join together in an I-push, without the quality of the weld by existing Shares of surface coating in the weld is reduced.
Weisen die Stahlsubstrate gemäß einer nächsten weiteren Ausführungsform des erfindungsgemäßen Verfahrens eine Korrosionsschutzbeschichtung, insbesondere eine Aluminium-Silizium(AlSi)-Oberflächenbeschichtung auf, kann mit dem erfindungsgemäßen Verfahren eine geschweißte Stahlkonstruktion mit sehr guten Korrosionseigenschaften bei gleichzeitig hoher Schweißnahtqualität zur Verfügung gestellt werden. Mit dem erfindungsgemäßen Verfahren ist es, wie bereits ausgeführt, möglich, nur in den Fügebereichen die Korrosionsschutzbeschichtung gezielt zu entfernen, so dass die gefügten Stahlsubstrate nahezu eine durchgehende Korrosionsschutzbeschichtung aufweisen. Darüber hinaus ist die Schweißnahtqualität besonders hoch, da im Wesentlichen kein Aluminium oder Silizium der Beschichtung in dem Fügebereich während des Verschweißens vorhanden ist.Point the steel substrates according to a next another embodiment of the invention Method, a corrosion protection coating, in particular a Aluminum-silicon (AlSi) surface coating on, can with the inventive method a welded Steel construction with very good corrosion properties at the same time high quality welds provided become. With the method according to the invention it, as already stated, possible only in the Joining areas the corrosion protection coating targeted to remove, so that the joined steel substrates almost have a continuous corrosion protection coating. Furthermore is the weld quality particularly high because essentially no aluminum or silicon in the coating the joint area during welding is available.
Vorzugsweise wird zur Beseitigung der Oberflächenbeschichtung diese im Fügebereich auf Schmelztemperatur erhitzt, so dass die Oberflächenbeschichtung durch das hochfrequente elektromagnetische Feld beispielsweise von der Fügekante weggetrieben wird. Es hat sich gezeigt, dass die Lorentzkraft hier genutzt werden kann, um die Beschichtung aus dem Fügebereich zu entfernen. Darüber hinaus kann gemäß einer nächsten Ausführungsform des erfindungsgemäßen Verfahrens die Oberflächenbeschichtung im Fügebereich der Stahlsubstrate so stark erhitzt werden, dass diese verdampft. Hierdurch kann die Oberflächenbeschichtung im Fügebereich ebenfalls entfernt werden, so dass eine gute Schweißnahtqualität beim Verbinden der Stahlsubstrate erzielt wird.Preferably This is to eliminate the surface coating heated in the joining area to melting temperature, so that the Surface coating by the high-frequency electromagnetic For example, field is driven away from the joining edge. It has been shown that the Lorentz force can be used here, to remove the coating from the joining area. About that In addition, according to a next embodiment of the inventive method, the surface coating be heated as much in the joint area of the steel substrates, that it evaporates. This allows the surface coating also be removed in the joining area, so that a good Weld quality when joining steel substrates is achieved.
Vorzugsweise besteht mindestens ein Stahlsubstrat aus einer Stahllegierung. Beispielsweise können über borhaltige, warmumformbare Stahllegierung, insbesondere über eine Stahllegierung vom Typ 22MnB5 gefügte Stahlsubstrate mit besonders hohen Festigkeiten bei geringem Gewicht zur Verfügung gestellt werden.Preferably At least one steel substrate consists of a steel alloy. For example, over boron-containing, hot-workable steel alloy, in particular via a steel alloy of the type 22MnB5 joined steel substrates with particularly high strength and low weight available be put.
Gemäß einer nächsten Ausführungsform des erfindungsgemäßen Verfahrens werden die Stahlsubstrate relativ gegenüber den Mitteln zur Erzeugung eines hochfrequenten, elektromagnetischen Feldes bewegt, so dass über die Relativgeschwindigkeit und/oder die Höhe des Induktionsstromes und/oder der Frequenz die Breite des Fügebereichs, in welchem die Korrosionsschutzschicht entfernt wird, einstellbar ist. Eine weitere Größe stellt der Koppelspalt dar, welcher dem Abstand zwischen Induktor und Stahlsubstrat entspricht. Dies ist unabhängig davon, ob die Mittel zur Erzeugung des elektromagnetischen Wechselfeldes über das Stahlsubstrat bewegt werden oder das Stahlsubstrat relativ zu den Mitteln zur Erzeugung des elektromagnetischen Feldes. In beiden Fällen wird mit zunehmender Einwirkdauer des hochfrequenten elektromagnetischen Feldes der Fügebereich der Stahlsubstrate stärker erwärmt bzw. die Oberflächenbeschichtung in einem breiteren Bereich entfernt.According to one next embodiment of the invention Method, the steel substrates are relatively opposite the means for generating a high-frequency, electromagnetic Field moves so that about the relative speed and / or the magnitude of the induction current and / or the frequency the width of the joint area in which the corrosion protection layer is removed, is adjustable. Another size represents the coupling gap, which is the distance between the inductor and steel substrate. This is independent of whether the means for generating the electromagnetic alternating field over the steel substrate or the steel substrate relative to the Means for generating the electromagnetic field. In both Cases increase with increasing exposure time of the high frequency electromagnetic field of the joining area of steel substrates heated more or the surface coating located in a wider area.
Schließlich ist es gemäß einer nächsten Ausführungsform des erfindungsgemäßen Verfahrens vorteilhaft, dass die Stahlsubstrate bandförmig sind und nach dem Entfernen der Oberflächenbeschichtung die bandförmigen Stahlsubstrate miteinander gefügt werden. Dies kann beispielsweise innerhalb einer einzigen Vorrichtung und in einem einzigen Banddurchlauf geschehen. Hierdurch wird eine besonders wirtschaftliche Möglichkeit geschaffen, oberflächenbeschichtete, bandförmige Stahlsubstrate, insbesondere „tailored Strips", miteinander zu fügen.After all it is according to a next embodiment advantageous for the process according to the invention, that the steel substrates are band-shaped and after removal the surface coating the band-shaped steel substrates be joined together. This can be done within a single device and in a single tape pass happen. This is a particularly economical way created, surface-coated, band-shaped Steel substrates, in particular "tailored strips" with each other to add.
Es gibt nun eine Vielzahl von Möglichkeiten das erfindungsgemäße Verfahren auszugestalten und weiterzubilden. Hierzu wird verwiesen einerseits auf die dem Patentanspruch 1 nachgeordneten Patentansprüche sowie auf die Beschreibung eines Ausführungsbeispiels des erfindungsgemäßen Verfahrens in Verbindung mit der Zeichnung.
