Description

Das übliche Plattierverfahren besteht darin, daß die zu verschweißenden Platinen, bei denen beispielsweise das Kernmetall aus Eisen und das Auflagemetall aus Nickel besteht, in sehr dünne, etwa 0,2 mm dünne Eisenbleche eingeschlagen, auf Schweißtemperatur erhitzt und dann ausgewalzt weiden. LJm ein Verschweißen zwischen Einschlagblech und Platinen nach Möglichkeit zu verhindern, beläßt man sowohl auf der inneren Seite des Einschlagbleches wie auch auf der Platine des Auflagemetalls die Walzhaut, letztere wird sogar durch isolierende Zwischenlagen, z. B. durch Anstriche, gelegentlieh noch verstärkt. Trotzdem tritt, wenn auch keine direkte Verschweißung, so doch eine starke Verklebung zwischen Platine und Einschlagblech ein, so daß zur einwandfreien Beseitigung des Einschlagbleches ein Beiz-The usual plating process is that the plates to be welded, in which, for example, the core metal consists of iron and the overlay metal consists of nickel, wrapped in very thin iron sheets about 0.2 mm thick, at welding temperature heated and then rolled out willow. LJm a weld between impact plate and to prevent sinkers as far as possible, one leaves both on the inner Side of the impact plate as well as the rolled skin on the plate of the facing metal, the latter is even provided by insulating intermediate layers, e.g. B. by painting, occasionally reinforced. Nevertheless, if there is no direct welding, there is nevertheless a strong bond between the board and the Drive-in plate so that a pickling

Es ist auch schon versucht worden, das Auflagemetall selbst zum Einschlagen des Kernmetalls zu benutzen und es an der Seite zum Abschluß der Luft einzuschlagen oder einzufalzen. Dieses Verfahren hat sich aber praktisch nicht durchsetzen können, da das Auflagemetall im allgemeinen zu dick und steif ist, um ein gutes luftdichtes Einschlagen zu ermöglichen.Attempts have also been made to use the overlay metal itself to hammer in the To use core metal and to hammer it on the side to close the air or to fold in. However, this procedure has not been able to establish itself in practice, since the Overlay metal is generally too thick and stiff to provide a good airtight envelope to enable.

Gemäß der Erfindung werden die genannten Nachteile vermieden und insbesondere auch ein Beizvorgang erspart. Zu diesem Zweck wird als Einschlagblech ein dünnes Blech aus dem Metall des Auflagematerials verwendet, das auf seiner Innenseite eine metallisch reine Oberfläche enthält und bei der Plattierung zusammen mit dem Auflagemetall auf das Kernmetall aufgeschweißt wird. Die Plattierung besteht also hierbei aus zwei verschiedenen -Einheiten, einmal dem eigent-According to the invention, the disadvantages mentioned are avoided and in particular a pickling process is also saved. For this purpose, a thin sheet metal sheet is used Sheet metal made from the metal of the overlay material used, which has a contains metallically pure surface and in the plating together with the overlay metal is welded onto the core metal. The plating consists of two here different units, once the actual

lichen Auflagemetall, was in nahezu der üblichen Stärke, lediglich vermindert um die Stärke des Einschlagbleches, aufgebracht wird, und zweitens aus dem eigentlichen Einschlagblech, was im Sinne der Erfindung aber kein Abfallmaterial mehr bildet, sondern in die Plattierung eingeht.union overlay metal, which is in almost the usual strength, only reduced by the Thickness of the impact plate, is applied, and secondly from the actual impact plate, which in the sense of the invention no longer forms waste material, but goes into the plating.

In Ausführung der Erfindung iwerden Kernmetall und Auflagemetall in üblicher WeiseIn carrying out the invention, the core metal and the clad metal are used in a conventional manner

to aneinandergelegt, wobei das Auflagemetall beiderseits gereinigt ist. Dann wird das sehr dünne Einschlagblech aus Auflagemetall, welches an seiner inneren Seite gereinigt ist, herumgelegt und in der üblichen Weise die Ränder so gefaltet, daß ein luftdichter Abschluß gewährleistet ist. Das so fertiggestellte Paket wird dann auf Schweißtemperatur erhitzt und ausgewalzt, wobei nicht nur das Auflagemetall mit Kernmaterial, sondern auch das Einschlagblech mit dem Auflage- »o metall völlig verschweißen.to placed next to each other, whereby the support metal is cleaned on both sides. Then it becomes very thin metal sheet, which has been cleaned on its inner side, laid around and folded the edges in the usual way so that an airtight seal is guaranteed. The thus finished package is then heated to welding temperature and rolled out, and not only the support metal with core material, but also the impact plate with the support »o completely weld metal.
