Metall- Metall-Verbindungen durch Schweißen von Werkstücken aus gleichen oder verschiedenen Metallen unlösbar zu verbinden ist bekannt. Beim Schweißen erfolgt die Verbindung der beiden Metalle durch ein Schmelzen der beiden Werkstoffe selbst an der Berührungsstelle oder mit einem metallischen Zusatzwerkstoff, der den zu verbindenden Metallen in seinen Eigenschaften ähnlich ist. Die Temperatur der Verbindungsstelle liegt über dem Schmelzpunkt des oder der Metalle. Beim Schweißen unterscheidet man im wesentlichen zwischen Preß- und Schmelzschweißen, wobei beim Preßschweißen die metallischen Werkstoffe unter Druck bei örtlich begrenzter Erwärmung und zwar im allgemeinen ohne Zusatzweirkstoffe vereinige werden und beim Schmelzschweißen die metallischen Werkstoffe unter Anwendung von Wärme durch örtlich begrenzten Schmelzfluß mit oder ohne Einschmelzen eines Zusatzwerkstoffes miteinander verbunden werden.Metal-to-metal connections cannot be released due to the welding of workpieces made of the same or different metals to connect is known. During welding, the two metals are joined by melting the both materials themselves at the point of contact or with a metallic filler material that is similar in its properties to the metals to be joined. The temperature of the connection point is above the melting point of the metal or metals. When it comes to welding, there is a difference one is essentially between pressure welding and fusion welding, with pressure welding the metallic Combine materials under pressure with localized heating, generally without additives and in fusion welding the metallic materials using heat through localized melt flow with or without melting of an additional material be connected to each other.

Bei den metallischen Halterungen der Figuren 2 und 3 ist die Schweißeinrichtung für das Punktschweißen aus Cründen der besseren Übersicht und der größeren Klarheit weggelassen.In the metallic brackets of Figures 2 and 3 is the welding equipment for spot welding from Cründen omitted for better overview and greater clarity.
Die in Figur 2 dargestellte Halterung 1 besteht aus zwei Metallstreifen 7 und 8, zwischen den ein Streifen 5 des Kunststoffmaterials 4 eingeklemmt ist. Die beiden Metallstreifen 7 und 8 sind an zumindest einer Punktschweißstelle 11, im vorliegenden Fall an drei Punktschweißstellen 11 direkt miteinander punktverschweißt, ohne daß Kunststoffmaterial 4 an den Punktschweiß steller« 11 dazwischen liegt. Des weiteren sind die Metallstreifen 7 und 8 durch das dazwischen befindliche Kunststoffmaterial 4 hindurch an den Punktschweißstellen 3 punktverschweißt. Bei der Herstellung dieser zweiteiligen Halterung 1 zeigt sich überraschenderweise, daß es nicht möglich ist, die Punktschweißstellen 3 herzustellen, so lange keine elektrische Verbindung zwischen den beiden Metallstreifen 7 und 8 besteht. Es ist somit erforderlich zuerst zwischen den Metallstreifen 7 und 8 eine elektrische Direktverbindung durch die Punktschweißstellen 11 herzustellen, bevor es gelingt, die Metallstreifen 7 und 8 durch das dazwischen befindliche Kunststoffmaterial hindurch an den Punktschweißstellen 3 zu verschweißen. Bisher war es nicht bekannt, durch eia dielektrisches Material hindurch eine Verbindung zwischenThe holder 1 shown in Figure 2 consists of two metal strips 7 and 8, between which a strip 5 of the Plastic material 4 is clamped. The two metal strips 7 and 8 are at least one spot weld 11, in the present case spot-welded directly to one another at three spot welds 11, without plastic material 4 to the spot welding operator " 11 lies in between. Furthermore, the metal strips 7 and 8 are through the plastic material located in between 4 spot welded through at the spot welds 3. In making this two-piece Bracket 1 surprisingly shows that it is not possible to produce the spot welds 3, so there is no electrical connection between the two metal strips 7 and 8 for a long time. It is therefore necessary first between the metal strips 7 and 8 a direct electrical connection through the spot welds 11 before it succeeds, the metal strips 7 and 8 through the plastic material in between through at the spot welds 3 weld. So far it was not known due to a dielectric Material through a connection between

Metallblechen durch elektrische Punktschweißung herstellen zu können.Manufacture metal sheets by electrical spot welding to be able to.
Die in Figur 3 gezeigte Halterung 1 besteht aus zwei Winkelblechen 9 und 10, die ebenso wie im Ausführungsbeispiel nach Figur 2 zuerst an den Punktschweißstellen 11 direkt miteinander verschweißt werden und erst danach durch den Streifen 5 des dazwischenliegenden Kunststorfmaterials 4 hindurch miteinander elektriscn punktverschweißt werden. Es müssen somit auch in diesem Fall die Winkelbleche erst durch Punktschweißung direkt miteinander verbunden werden, bevor durch das Kunststoffmaterial hindurch die Winkelblechen miteinander verschweißt werden können.The bracket 1 shown in Figure 3 consists of two angle plates 9 and 10, the same as in the embodiment according to Figure 2 are first welded directly to one another at the spot welds 11 and only then through the strip 5 of the intermediate synthetic peat material 4 are electrically spot-welded to one another through this. In this case too, the Angle plates only through spot welding directly to one another are connected before the angle plates are welded together through the plastic material can.
Bei den Ausführungsbeispielen nach den Figuren 2 und 3 können die Metallstreifen bzw. die Winkelbleche sich untereinander dickenmäßig unterscheiden. Üblicherweise bestehen die Metallstreifen bzw. die Winkelbleche aus dem gleichen Metall, jedoch sind auch unterschiedliche Metalle denkbar, soweit diese aufgrund ihrer unterschiedlichen Zusammensetzung miteinander elektrisch punktverschweißt werden können.In the exemplary embodiments according to FIGS. 2 and 3, the metal strips or the angle plates can be differ from each other in terms of thickness. Usually the metal strips or the angle plates consist of the same metal, but different metals are also conceivable, provided that they are different because of their different Composition can be electrically spot welded together.
