Description
Gegenstand der Erfindung ist eine Schweiß-. elektrode, die aus einem metallischen Kern mit eimer Pastenumhüllung besteht.The invention is a welding. electrode made of a metallic core with a bucket of paste wrapping.
Lichtbogenschweißelektroden, deren Kern mit einer pastenförmigen Masse umhüllt ist, sind allgemein bekannt. Es ist auch bereits bekannt, bei solchen Elektroden auf die Umhüllung eine Lage mit Wasserglas getränkten Papiers aufzubringen oder sie mit Asbestpapier und einer darübergewickelten Lage Asbestgarn zu umgeben. Ferner sind Lichtbogenschweißelektroden'' bekannt, um deten Metallkern mehrere Lagen Asbestpapier gewickelt sind.Arc welding electrodes, the core of which is coated with a paste-like mass, are well known. It is also already known to apply such electrodes to the casing Apply a layer of paper soaked with water glass or asbestos paper and a layer of asbestos thread wrapped over it. Furthermore, arc welding electrodes '' known to have several layers of asbestos paper wrapped around the metal core.
Wie jedoch umfangreiche Vergleichs versuche mit den bekannten Schweißelektroden unter Verwendung von Gleich- und Wechselstrom gezeigt haben, und zwar sowohl mit Elektroden, die entweder nur eine PastenumhüllungHow, however, extensive comparison attempts with the known welding electrodes under Have shown the use of direct and alternating current, both with electrodes, which is either just a paste wrapping
ao besitzen oder nur mit Asbestpapier umwickelt sind, als auch mit Elektroden, deren Pastenumhüllung nicht nur mit Asbestpapier, sondern darüber noch mit Asbestgarn umwickelt ist, und mit Elektroden, auf deren Pastenumhüllung eine Lage mit handelsüblichem unverdünntem Wasserglas getränktes Löschpapier aufgebracht ist, entsteht dort ein Krater nicht oder nur unvollkommen. Wenn jedoch erfindungsgemäß auf die Pastenumhüllung lediglich ein gleichmäßig dünnes Papier aus faserigem Silicat, z. B. Asbestpapier, aufgebracht wird, bildet sich im Unterschied zu diesen bekannten Elektroden beim Abbrennen an der Elektrode ein überstehender Krater aus Asbestpapier. Durch diesen Asbestpapierkrater wird die Wärme am Elektrodenende besonders gut zusammengehalten; infolgedessen fließt der Werkstoff, der beim Übergehen in die Schweißraupe mit einer schützenden Hülle von durch die Wärmeanhäufung im Krater dünnflüssig gehaltener Schlacke umgeben ist, leichter als bei den bekannten Elektroden und ergibt daher auch eine glattere Raupe als diese.ao own or are only wrapped with asbestos paper, as well as with electrodes, whose paste coating is not only wrapped with asbestos paper, but also with asbestos thread, and with electrodes on the paste cover If a layer of blotting paper soaked in commercially available undiluted water glass is applied, there is a Crater not or only imperfectly. If, however, according to the invention on the paste coating only a uniformly thin paper made of fibrous silicate, e.g. B. asbestos paper, is applied, forms in contrast to these known electrodes when Burning off a protruding crater made of asbestos paper on the electrode. Through this Asbestos paper crater, the heat is held together particularly well at the end of the electrode; As a result, the material that flows into the weld bead with a protective shell is surrounded by slag, which is held in a thin liquid by the accumulation of heat in the crater, lighter than with the known electrodes and therefore also gives a smoother bead than this.
Bei der Herstellung der Elektrode nach der Erfindung geht man so vor, daß die mit der Pastenumhüllung versehene Elektrode mit dem Asbestpapier der Länge nach umwickelt wird, so daß sich eine gleichmäßig dünne Asbestpapierschicht ergibt, die mit Hilfe einer auf die Paste während des Ummantelungsvorganges aufgebrachten Natriumsilicatlösung festgehalten werden kann.In the manufacture of the electrode according to the invention one proceeds so that the With the paste coating provided electrode with the asbestos paper is wrapped lengthways, so that a uniform thin asbestos paper layer results, which with the help of a on the paste during the wrapping process applied sodium silicate solution can be held.
