The present invention relates to a method for making electrical parts on a metal wall made of a material that is easily oxidized on the surface, such as, for example, titanium flakes or aluminum, especially for the manufacture of electrolytic devices. . If the invention is not limited to the use of an electrolytic device to manufacture ~ t halogen gas produced by a thin age-state-solution, there will be problems such as production, because this device is made of a half-shell, which The unit is composed and then packaged, with the respective rear wall positioned on the front wall, and an electrical path must be ensured from one wall to the other. For example, the application w 0 9 8/1 5 0 7 5 is a well-known electrolytic device and a method for manufacturing the same. Here, a contact piece on a wall existing in contact with each other is provided, which is used in a laser-welding method. Coated. If this manufacturing method already has significant advantages, there is a problem therein, that is, it is relatively expensive to manufacture such a contact sheet. Therefore, for example, a nickel foil is coated on a titanium foil by spraying Fe plating. This plate composed of two metals is cut into pieces, and deep grooves need to be milled in the nickel layer in the longitudinal direction. The titanium sheet underneath was milled together, so the nickel sheet was positioned on a U-shaped titanium base. This contact is then soldered onto it. Please refer to the US patent documents USP3610874,4108752,4414444,41687264,5315758, as well as the German patents for the conventional technology; 丨 documents DE-2 4 4 8 7 1 3-A 1 and DE 3 9 0 1 3 1 9-A 1. @ 1H: The object of the present invention is to establish a solution, which provides a basic material (such as the titanium flakes mentioned above), which has # Μ + which has particularly good conductive contact properties, Design or coating material, its very good electrical conductivity, in order to produce the most suitable --_ g correction!

Description of the invention (3) The invention will be further described below with reference to the drawings. Brief description of the drawings * Figures 1 to 4 are cross sections of a contact sheet via laser-print-welding, which has a flat connection on the titanium rear wall of the electrolytic device, which is flat and laser-welded. . Figures 5 and 6 are cross-sections of modified examples of elasticity. The simplified cross-section diagrams together show that 1 represents a contact piece, which is composed of a titanium sheet 2 with a copper wire 3 welded thereto, wherein this contact piece 2/3 is used in an electrolytic device that is not further explained 4 represents the rear wall, which is fixed by means of continuous laser welding via seam 5, and in the area of the current separator represented by 6, it may be composed of titanium again. The laser welding is illustrated in FIG. 1, and the laser-printing-welding of the contact piece 2 is illustrated in FIG. 2. The parts having the same functions in this regard have the same reference numbers in the drawings. In addition to the illustrations in Figures 1 and 2, this contact piece is illustrated in Figures 3 and 4 as a rectangular cross-section piece, which has the reference number 3 ', which is shown in Figure 4 and also in Figure 4. In Figs. 5 and 6, there is additionally provided another solder, commonly represented by 7, between the contact piece 3 or 3 'and the titanium sheet 2. Of course, the embodiment of the present invention described here can be modified in many aspects without departing from its basic idea. Therefore, the present invention is not limited by the geometric shapes described herein, nor is it limited by the individual materials, among which those mentioned in the specification are particularly suitable here. 503606 V.
