Description
Das Aufschweißen von dünnwandigen Profilen auf dünne Bleche mittels des elektrischen Abbrennverfahrens stößt auf Schwierigkeiten, weil meistens kein einwandfreie^ S Verschweißen, sondern lediglich ein Verkleben des Profils mit dem dünnen Blech eintritt.The welding of thin-walled profiles onto thin sheets by means of the electrical Burning process encounters difficulties because mostly no proper ^ S Welding, but simply gluing the profile to the thin sheet metal entry.
Nach der Erfindung wird eine einwandfreie Schweißung dadurch erreicht, 'daß an dem ίο dünnen Blech die Sitzfläche für das aufzuschweißende Profil schlechter gekühlt wird als die unmittelbar dieser Sitzfläche benachbarten Blechteile. Die Stauchung wird dabei nach möglichst kurzer Abbrenndauer schlagartig ausgeführt.According to the invention, a perfect weld is achieved 'that on the ίο thin sheet metal, the seat for the profile to be welded on is less cooled than the sheet metal parts immediately adjacent to this seat. The compression is thereby after The shortest possible burning time is carried out abruptly.
Die Erfindung soll an Hand der Zeichnung näher erläutert werden.The invention will be explained in more detail with reference to the drawing.
Fig", ι zeigt in schematischer Darstellung die Elektrodenanordnung zum Anschweißen eines Henkels, der das in Fig. 2 'dargestellte Querschnittsprofil hat, an einem Kochtopf.Fig ", ι shows a schematic representation the electrode arrangement for welding on a handle, the one shown in Fig. 2 ' Has cross-sectional profile on a saucepan.
In den Fig. 3 und 4 sind andere Ausführungsformen für die Gegenelektrode dargestellt. In FIGS. 3 and 4, other embodiments for the counter electrode are shown.
In Fig. ι ist mit 1 der Kochtopf bezeichnet, an den der Henkel 2 mit dem in Fig. 2 dargestellten Querschnittsprofil anzuschweißen ist. Zu diesem Zweck ist an die Koehtopfwand die Kupferelektrode 3 angelegt, die an den Sitzstellen des Henkels 2 eine Aussparung 4 besitzt, die so· groß ist, daß die Sitzstelle wesentlich schlechter gekühlt ist als die unmittelbar dieser Sitzfläche benachbarten Blechteile des Kochtopfes. Die Tiefe dieser Aussparungen wird zweckmäßig so gewählt, daß sie nur Bruchteile eines Millimeters beträgt. In Fig. Ι 1 denotes the saucepan, to be welded to the handle 2 with the cross-sectional profile shown in FIG is. For this purpose, the copper electrode 3 is placed on the Koehtopfwand, which is on the seat points of the handle 2 has a recess 4 which is so large that the Seat is cooled much worse than that directly adjacent to this seat Sheet metal parts of the saucepan. The depth of these recesses is expediently chosen so that that it is only a fraction of a millimeter.
Die Aussparung 4 kann in die volle Kupferelektrode eingefräst sein. Statt dessen kann man aber auch, wie die Fig. 3 zeigt, auf die Elektrode eine dünne Kupferschablone 5 aufbringen, in die den Sitzflächen entsprechende: Öffnungen eingearbeitet sind.The recess 4 can be milled into the full copper electrode. Instead, you can but you can also, as Fig. 3 shows, apply a thin copper stencil 5 to the electrode, in the openings corresponding to the seat surfaces: are incorporated.
Bei der in Fig. 4 dargestellten Ausführungsform ist die Aussparung der Kupferelektrode mit einem die Wärme schlecht leitenden Material 6, wie Steatit, Porzellan o. dgl., ausgefüllt. In the embodiment shown in FIG. 4, the recess is the copper electrode filled with a material 6, which does not conduct heat well, such as steatite, porcelain or the like.
Der Henkel selbst wird mit einer zangenartigen Elektrode 7 (Fig. 1) gefaßt. 8 ist die Sekundärwicklung des Schweißtransformators, die mit dem einen Pol an die Elektrode 3, mit dem anderen Pol an die Zange 7 angeschlossen ist. Die Schweißung selbst wird mit dieser Anordnung, wie erwähnt, so ausgeführt, daß nach ganz kurzzeitigem Abbrennen der Henkel 2 kräftig auf die über der Aussparung 4 liegenden Wandteile des Kochtopfes gestaucht wird. Dabei werden die Sitzflä'chen selbst stärker erhitzt als die unmittei-The handle itself is grasped with a pincer-like electrode 7 (FIG. 1). 8 is the Secondary winding of the welding transformer, one pole to the electrode 3, with the other pole is connected to the clamp 7. The weld itself is carried out with this arrangement, as mentioned, in such a way that that after a very brief burning of the handle 2 vigorously on the wall parts of the saucepan lying above the recess 4 is compressed. The seats themselves are heated more strongly than the

bar diesen Sitzflächen benachbarten Wandteile, weil dort infolge der Aussparung der Elektrode bzw. des unter den Sitzflächen liegenden schlechten Wärmeleiters die Kühlung wesentlich schlechter ist als an den Stellen, an denen die gut wärmeleitende Kupferelektrode unmittelbar an der Kochtopfwand anliegt. Dadurch ist die Gewähr gegeben, daß der Henkel einwandfrei mit ι ο der Kochtopfwand verschweißt wird.without wall parts adjacent to these seats, because there as a result of the recess in the electrode or under the seat surfaces lying bad heat conductor the cooling is much worse than on the Places where the highly thermally conductive copper electrode is directly on the wall of the saucepan is present. This ensures that the handle is properly welded to the cooking pot wall.
In ähnlicher Weise können auch dünnwandige I-Profüe u. dgl. an dünne Bleche angeschweißt werden.In a similar way, thin-walled I-profiles and the like can also be welded to thin metal sheets will.
