Definitions
- the invention relates to a method for joining a
- Composite sheet metal part at least two outer cover plates and
- Component has at least one outer metallic layer, wherein the composite sheet metal part and the further component overlap each other between two electrodes
- the invention relates to a device for joining a
- Composite sheet metal part at least two outer cover plates and at least one arranged between the cover plates
- Composite sheet metal parts are composite materials, which are constructed in particular in the form of a sandwich.
- Composite sheet metal parts usually consist of two outer cover sheets and one
- composite sheet metal parts can have very high local stiffnesses and strengths.
- composite sheet metal parts can have good sound insulating properties provide.
- composite sheet metal parts also allow a lower component weight, without sacrificing the other properties of the component. For this reason, composite sheet metal parts are increasingly being used as so-called lightweight sheets in motor vehicle construction.
- Resistance welding are suitable. Resistance welding, for example, is used to easily and inexpensively join the composite sheet metal parts to normal sheet metal parts. In resistance welding, there is a brief, high heat input into the composite sheet metal part, whereby the at least one between the cover plates
- non-metallic layer can be easily damaged. This is the case in particular with plastic layers, which have a lower temperature resistance and, in addition, a lower thermal conductivity than the outer cover plates.
- the plastic layers may also be electrically insulating or at least have a very low electrical conductivity.
- the present invention is therefore based on the object, the method and the device in each case of the type mentioned above and described in more detail above
- KJ / nb 110616 O April 23, 2012 is brought and in which at least one current path between the two electrodes via an electrically conductive
- the invention has therefore recognized that, in order to protect the composite sheet metal part during the joining at locally particularly stressed areas, a dummy element can be used, which is brought into contact with the composite sheet metal part.
- the dummy element is electrically conductive and preferably thermally stable.
- the dummy element may, for example, be very similar to the cover sheet in terms of these properties.
- the dummy element and the outer cover sheets may be made of the same or a similar material.
- the dummy element has a much higher conductivity and / or considerably higher thermal stability. It may then be sufficient to improve the material quality of the dummy element instead of the outer cover plate.
- In resistance welding at least two electrodes are positioned relative to the workpieces to be welded in such a way that between the electrodes an electrically conductive
- Workpieces are in this case the composite sheet metal part and the other component.
- the electrodes may be designed differently and may be formed, for example, as part of a welding tongs or as roller electrodes.
- the dummy element is in at least one at
- Dummy element can also be closed otherwise.
- the dummy element can be a local

- the dummy element is characterized by the fact that, preferably, for the mechanical and other properties of the
- Composite sheet is dispensable.
- the dummy element therefore only needs to be provided where locally elevated temperatures can occur during resistance welding.
- the dummy element is not permanently connected by the resistance welding with the composite sheet metal part, but sooner or later falls off the composite sheet metal part or removed.
- the dummy element can so for example only for the duration of resistance welding, so the joining, with the
- the dummy element can also be quite material-intensive, as a solid plate, made.
- the dummy element to bring into contact with the outer cover plate, which is not in contact with the overlapping with the other component, in particular when the further component and the composite sheet metal part are formed flat.
- the dummy element is preferably provided on the outer cover plate facing away from the further component.
- the further component may be an ordinary sheet metal component. It is also conceivable that the further component is a solid metallic component or even a composite material, such as a composite sheet metal part. In order to ensure the weldability of the composite sheet metal part with the other component, the further component, if it is not constructed continuously metallic, in particular at least one outer metallic layer which can be brought into contact with the composite sheet metal part and welded. In a first embodiment of the method, at least one current path between the two electrodes via the
- Dummy element and the two outer cover plates are closed. In this way it can be achieved that a part of the current flows through the dummy element, which would otherwise flow through an outer cover layer.
- the dummy element is provided between an outer cover layer and the electrode so that the current flows through the dummy element into the outer cover layer or vice versa, the current density in the outer cover plate adjacent to the dummy element can be reduced.
- the dummy element may alternatively or additionally but also a part of the heat generated during welding
- the electrode may be brought into abutment with the dummy element to approximately a current path through the
- the dummy element is then preferably associated with a composite sheet metal part
- Electrode brought into contact.
- a current path between the two electrodes can be closed via the dummy element and the electrically conductive component.
- the current path can be so, for example, under partial or preferably
- Composite sheet metal part leads and so also to a
- a procedurally simple implementation can be achieved if the dummy element is received in an electrically conductive connected to the other component recording.
- the recording is preferably used at the same time
- Positioning of the dummy element during welding is preferably carried out before the actual joining. However, the dummy element can also be taken up or positioned within certain limits only during joining. Alternatively or
- a plurality of dummy elements provided on a carrier tape can be used. This is particularly advantageous when the carrier tape is moved between an electrode and the composite sheet metal part. This is preferably done between two
- join events where the join events are also two

- the carrier tape can ultimately in a corresponding
- a holder for the carrier tape is fixed relative to an electrode.
- the positioning is preferably automatic.

- Composite sheet metal part to be removed If the dummy element is to be partially removed, it may be expedient to provide at least one corresponding predetermined breaking point in the dummy element, which facilitates a separation of remaining and to be removed dummy parts.
- dummy elements exert a favorable effect if they consist of a material of high electrical conductivity and high melting temperature.
- Conductivities and melting temperatures of the dummy element can be achieved so that the dummy element is not joined to the composite sheet metal part.
- the dummy element can then be used repeatedly for a plurality of joining events, without being significantly damaged or having to be separated again from the composite sheet metal part.
- a solid plate can be used as a dummy element whose thickness is the thickness of the composite sheet metal part and / or an outer
- Cover sheet can significantly exceed.
- a cooling of the dummy element may alternatively or additionally provided a cooling of the dummy element. If the dummy element is held in a receptacle, alternatively or additionally, the receptacle can be cooled. As cooling medium are water, oil or other fluid in question. The cooling can be done via appropriate cooling channels.
- Engraving are used.
- the embossments such as in the form of thorns, thereby piercing an outer cover plate.
- Gases from a non-metallic layer can then be removed by at least one corresponding venting channel.
- the described method can be used in resistance spot welding. There is only a selective amount of heat in the
- Inserted composite sheet metal part and it can be particularly simple and inexpensive dummy elements, such as in the form of
- a receptacle for receiving a dummy element before and / or during joining and for contacting the dummy element is provided with the composite sheet metal part and that the receptacle electrically conductive with the further component connected is.
