Description
Bekanntlich ist es vorteilhaft, Schweißstäbe mit einem sog. schlackenbildenden Stoff zu versehen. Meist wird dieses Material in Form einer Verkleidung auf die Außenseite des Schweißmaterials aufgebracht; es ist aber auch bekannt, den schlackenbildenden Stoff in Form eines Kerns vom Schweißmetall umgeben zu lassen.It is known that it is advantageous to use welding rods with a so-called slag-forming substance to provide. Mostly this material is in the form of a cladding on the outside the welding material applied; but it is also known to be the slag-forming substance to be surrounded by the weld metal in the form of a core.
Die Erfindung bezieht sich auf Schweißstäbe der zuletzt erwähnten Art und bezweckt, in einfacher Weise einen Schweißstab herzustellen, dem genügende Biegsamkeit gegeben werden kann, um auf einfache Weise zum selbsttätigen Schweißen verwendet werden zu können.The invention relates to welding rods of the last mentioned type and aims to produce a welding rod in a simple manner, given sufficient flexibility can be used in a simple manner for automatic welding too can.
Erfindungsgemäß wird zu diesem Zweck ein mit Aussparungen versehenes Band ans Schweißmetall in der Weise schraubenförmig aufgewickelt, daß es eine Röhre bildet, bei welcher die Kanten des Bandes aneinanderstoßen. Das Innere dieser Röhre wird dann ausgefüllt mit schlackenbildendem Stoff, der durch die ausgesparten Öffnungen des aufgewickelten Bandes hineingepreßt wird.According to the invention, a band provided with recesses is used for this purpose Welding metal wound helically to form a tube which the edges of the tape butt against each other. The inside of this tube then becomes filled with slag-forming material, which is wound through the recessed openings of the Tape is pressed into it.
Die Erfindung ist in der Zeichnung näher erläutert.The invention is explained in more detail in the drawing.
Fig. ι stellt ein mit Öffnungen 1 versehenes Band 2 aus Schweißmetall dar. Dieses Metallband wird, wie dies in Fig. 2 dargestellt ist, schraubenlinienförmig in Form einer Röhre gewickelt. Sodann wird die Röhre mit schlakkenbildendem Stoff 3 ausgefüllt, wie dies nachstehend näher erläutert ist. Das Wickeln wird derart vorgenommen, daß die Kanten des Bandes aneinander anliegen, was für das Zuführen des elektrischen Stromes beim selbsttätigen Schweißen günstig ist.Fig. Ι represents a 1 provided with openings Band 2 made of weld metal. This metal band is, as shown in Fig. 2, wound helically in the form of a tube. Then the tube is lump-forming Completed substance 3 as explained in more detail below. The swaddling will made in such a way that the edges of the tape lie against each other, which is responsible for the supply of electrical current during the automatic Welding is cheap.
Fig. 3 stellt ein Metallband 4 mit Aussparungen 5 dar. Dieses Metallband 4 ist inFig. 3 shows a metal band 4 with recesses 5. This metal band 4 is in
4.0 Fig. 4 in schraubenlinienförmig gewickeltem und mit schlackenbildendem Stoff 3 versehenem Zustande veranschaulicht.4.0 Fig. 4 in a helically wound and illustrated states provided with slag-forming substance 3.
Fig. 5 zeigt andeutungsweise eine Vorrichtung, durch die der schlackenbildende Stoff 3 in die vorher beschriebenen Schweißstäbe eingebracht werden kann. Mit 6 ist ein Gefäß bezeichnet, das das schlackenbildende Material 3 enthält und in dem ein Kolben 7 niedergedrückt werden kann. Der Schweißstab 8 wird durch die Öffnungen 9 und ι ο durch das Gefäß 6 hindurchgeführt, wobei gleichzeitig das schlackenbildende Material^ mittels des Kolbens 7 durch die ausgesparten Öffnungen des schraubenlinienförmig gewickelten Bandes hindurch in das Innere gepreßt wird. Es versteht sich von selbst, daß sich der schlackenbildende Stoff, nachdem er an dem Führungsende 10 des Gefäßeso vorbeigegangen ist, in so hartem Zustande befinden muß, daß infolge des Preßdruckes dieser schlackenbildende Stoff nicht durch die Öffnungen der Röhrenwand hindurch wieder nach außen gepreßt wird. Mit n ist andeutungsweise eine Vorrichtung bezeichnet, durch die der Schweißstab 8 weitergezogen werden kann.5 shows an outline of a device by which the slag-forming substance 3 can be introduced into the previously described welding rods. With 6 there is a vessel denotes, which contains the slag-forming material 3 and in which a piston 7 is depressed can be. The welding rod 8 is through the openings 9 and ι ο through the Vessel 6 passed through, at the same time the slag-forming material ^ by means of the Piston 7 through the recessed openings of the helically wound band is pressed through into the interior. It goes without saying that the slag-forming Fabric after passing the leading end 10 of the vessel in must be in such a hard state that due to the pressure this slag-forming Substance not pressed out again through the openings in the tube wall will. With n is indicated a device through which the Welding rod 8 can be pulled further.
