Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Verschweißen von Bauteilen eines Kraftfahrzeuges, auf eine Schweißbaugruppe sowie auf einen Fahrzeugsitz für ein Kraftfahrzeug mit einer derartigen Baugruppe.The present invention relates to a method for welding components of a motor vehicle, to a welding assembly and to a vehicle seat for a motor vehicle with such an assembly.
Bei der Konstruktion von Kraftfahrzeugen erlangen zur Reduktion des Gesamtgewichtes des Kraftfahrzeuges Leichtbaukonstruktionen zunehmend an Bedeutung. Dies betrifft neben dem Antriebsstrang, dem Fahrwerk und der Karosserie auch die Innenraumausstattung, wie beispielsweise die Fahrzeugsitze. Ein derartiger Fahrzeugsitz für ein Kraftfahrzeug ist beispielsweise in der
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zur Verfügung zu stellen, welches es ermöglicht, Bauteile, die keine gemeinsame Schweißeignung aufweisen, miteinander zu verschweißen.Against this background, the object of the present invention is to provide an improved method which makes it possible to weld components which do not have common weldability to one another.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 und/oder durch eine Schweißbaugruppe mit den Merkmalen des Patentanspruchs 10 gelöst.This object is achieved by a method having the features of
Demgemäß ist ein Verfahren zum Verschweißen von Bauteilen eines Kraftfahrzeugs mit folgenden Verfahrensschritten vorgesehen: Bereitstellen eines ersten Bauteils, welches einen aus einem ersten Basismaterial gebildeten ersten Verbindungsabschnitt aufweist; Bereitstellen eines zweiten Bauteils, welches einen aus einem zweiten Material gebildeten zweiten Verbindungsabschnitt aufweist; Vorsehen einer metallischen Beschichtung auf mindestens dem ersten Verbindungsabschnitt, wobei die metallische Beschichtung mit einem Beschichtungsmaterial gebildet wird, welches mit dem zweiten Material des zweiten Verbindungsabschnitts verschweißbar ist; und Verschweißen des ersten und zweiten Bauteils miteinander, wobei der beschichtete erste Verbindungsabschnitt mit dem zweiten Verbindungsabschnitt verschweißt wird.Accordingly, a method for welding components of a motor vehicle is provided with the following method steps: providing a first component which has a first connecting portion formed from a first base material; Providing a second component having a second connecting portion formed of a second material; Providing a metallic coating on at least the first connecting portion, wherein the metallic coating is formed with a coating material which is weldable to the second material of the second connecting portion; and welding the first and second components together, wherein the coated first connection portion is welded to the second connection portion.
Ferner ist eine Schweißbaugruppe für ein Kraftfahrzeug vorgesehen, mit: einem ersten Bauteil, welches einen aus einem ersten Basismaterial gebildeten ersten Verbindungsabschnitt aufweist; einem zweiten Bauteil, welches einen aus einem zweiten Material gebildeten zweiten Verbindungsabschnitt aufweist; und einer mindestens auf dem ersten Verbindungsabschnitt vorgesehenen metallischen Beschichtung, wobei die metallische Beschichtung mit einem Beschichtungsmaterial gebildet ist, welches mit dem zweiten Material des zweiten Verbindungsabschnittes verschweißt ist.Further, there is provided a welding assembly for a motor vehicle, comprising: a first member having a first connecting portion formed of a first base material; a second member having a second connecting portion formed of a second material; and a metallic coating provided at least on the first connecting portion, wherein the metallic coating is formed with a coating material which is welded to the second material of the second connecting portion.
Die der vorliegenden Erfindung zugrunde liegende Idee besteht darin, zum Verschweißen zweier Bauteile zwischen den beiden Bauteilen eine metallische Beschichtung vorzusehen, welche mit einem der beiden Bauteile verbunden ist und welche derart ausgebildet ist, dass diese mit dem Material des unbeschichteten Bauteils verschweißbar ist. Hierdurch ist es vorteilhaft möglich, zwei mit einem gewählten Schweißverfahren bzw. mit bestimmten Schweißparametern konventionell unverschweißbare Bauteile miteinander zu verschweißen. Das vorliegende Verfahren ermöglicht beispielsweise vorteilhaft den Ersatz eines metallischen Fügepartners durch einen mit einem Kunststoffwerkstoff gebildeten Fügepartner, wobei die Vorteile des Schweißverfahrens insbesondere gegenüber einer formschlüssigen Verbindungstechnik, wie beispielsweise Automatisierbarkeit, Schnelligkeit, Wegfall zusätzlicher Befestigungselemente bei der Ausbildung der Verbindung erhalten bleiben. Dies ermöglicht die Herstellung hochintegrierter Schweißbaugruppen in einem automatisierbaren Verfahren bei deutlich reduziertem Gewichtsaufwand.The idea underlying the present invention is to provide for the welding of two components between the two components, a metallic coating which is connected to one of the two components and which is designed such that it can be welded to the material of the uncoated component. As a result, it is advantageously possible to weld two components that are conventionally nonweldable using a selected welding method or with specific welding parameters. The present method allows, for example, advantageously the replacement of a metallic joining partner by a joining partner formed with a plastic material, the advantages of the welding process in particular over a positive connection technology, such as automation, speed, elimination of additional fasteners remain in the formation of the compound. This allows the production of highly integrated welding assemblies in one automatable process with significantly reduced weight.
Vorteilhafte Ausgestaltungen und Weiterbildungen der vorliegenden Erfindung ergeben sich aus den weiteren Unteransprüchen und aus der Beschreibung in Zusammenschau mit den Figuren der Zeichnung. Advantageous embodiments and further developments of the present invention will become apparent from the other dependent claims and from the description in conjunction with the figures of the drawing.
In einer bevorzugten Ausgestaltung des Verfahrens wird das miteinander Verschweißen des ersten und zweiten Bauteils mittels eines Laserstrahlschweißverfahrens durchgeführt. Hierdurch ist es vorteilhaft möglich, mit hoher Schweißgeschwindigkeit, schmaler Schweißnahtform und geringem thermischen Wärmeeintrag die Bauteile zu fügen. Dies ermöglicht hohe Taktzeiten bei der Anwendung des Verfahrens, wodurch dessen Anwendungsbereich erweitert wird.In a preferred embodiment of the method, the welding together of the first and second component is carried out by means of a laser beam welding method.
