Claims (1)

Bei der Lichtbogenschweißung ist es schädlich, daß die Luft an die erhitzten Teile des die eine Elektrode bildenden Werkstücks und an den von der Schweißelektrode herabtropfenden oder -fließenden Elektrodenstoft* ungehindert herantreten kann. Dadurch tritt sowohl eine Oxydation des Werkstücks an den Schweißstellen als auch eine Oxydation des Schweißstoffes ein, so daß die Schweißstelle eine Einbuße an Einheitlichkeit und damit an Festigkeit erleidet.With arc welding it is harmful that the air reaches the heated parts of the workpiece forming one electrode and of those dripping down from the welding electrode or flowing electrode material * can approach it unhindered. This occurs both an oxidation of the workpiece at the welds and an oxidation of the weld material, so that the weld is a loss of uniformity and thus suffers from strength. Alan hat diesem Übelstand schon dadurch \orzubeugen versucht, daß man die Elektrode mit einem Überzug aus Asbest oder ähnlichem Stoff überzogen hat, der dann über die Elektrode etwas übersteht und schließlich schmilzt. Er soll dann einen Überzug aus Schlacke über die Schweißstellen bilden; häufig jedoch vermischt er sich mit dem heruntergetropften oder heruntergeflossenen Schweißstoff und gefährdet so die Einheitlichkeit und Festigkeit der Schweißung.Alan has already tried to prevent this problem by removing the electrode covered with a coating of asbestos or similar material, which then over the electrode something survives and eventually melts. It should then form a coating of slag over the welds; but often it mixes with what has dripped or flowed down Weld material, endangering the uniformity and strength of the weld. Nach der Erfindung soll dieser Mangel dadurch beseitigt werden, daß die Schweißelektrode in einem Rohr aus feuerbeständigem Stoff vorgeschoben wird, der möglichst dicht auf das Werkstück aufgesetzt wird.According to the invention, this deficiency should be eliminated in that the welding electrode is advanced in a tube made of fire-resistant material, which is placed as close as possible to the workpiece. Die Abb. 1 zeigt ein Beispiel der Erfindung, ι ist ein Rohr aus feuerfestem Stoff, in dem der Schweißdraht 2 vorgeschoben wird. 3 ist das Werkstück.Fig. 1 shows an example of the invention, ι is a tube made of refractory material, in which the welding wire 2 is advanced will. 3 is the workpiece. Die Schweißelektrode kann von Hand oderThe welding electrode can be done by hand or auch durch einen mechanischen Antrieb über eine biegsame Welle, z. B. eine sogenannte Drahtspirale, vorgeschoben werden. Die 35 Abb. 2 zeigt hierfür ein Beispiel: Durch die biegsame Welle 4 wird eine kleine Schnecke 5 gedreht, in die das Zahnrad 6 eingreift. Ein kleines mit dem Zahnrad 6 verbundenes Zahnrad 7 greift in den gezahnten Halter 8 40 für die Elektrode 2 ein und verschiebt diese so relativ zum Rohr 1, das mit einem Bügel 9 an der Lagerung der Schnecke befestigt ist. Bei Bedarf kann der Antrieb ausgeschaltet oder geregelt werden, so daß die Elektrode 45 gegen das Rohr vorgeschoben werden kann, wie es das Fortschreiten der Arbeit nötig macht.also by a mechanical drive via a flexible shaft, e.g. B. a so-called Wire spiral to be advanced. 35 Fig. 2 shows an example of this: Through the Flexible shaft 4, a small worm 5 is rotated into which the gear 6 engages. A The small gear 7 connected to the gear 6 engages in the toothed holder 8 40 for the electrode 2 and thus moves it relative to the tube 1, which is connected to a bracket 9 is attached to the storage of the screw. If necessary, the drive can be switched off or regulated so that the electrode 45 can be advanced against the pipe, as the progress of the work makes it necessary.
