Elektrisches Lötverfahren. Patentiert im Deutschen Reiche vom 29. August 1911 ab.Electric soldering process. Patented in the German Empire on August 29, 1911.
Beim Schweißen auf elektrischem Wege hielt man bisher die Elektrode in der Hand, brachte sie in Kontakt mit dem Werkstück, zog sie zurück, um den Bogen zu erzeugen, und ging dann mit der Elektrode über das Werkstück hin. Bei Metallelektroden ist es dabei schwierig, die Elektrode sicher zu halten und in gleichförmigem, genauem Abstande vom Werkstück zu führen; dies trifft nament-Hch bei kleineren Werkstücken zu, wenn der Strom vergleichsweise schwach und daher der Bogen kurz ist.When welding electrically, the electrode was previously held in the hand, brought it into contact with the workpiece, pulled it back to create the arc, and then went over the workpiece with the electrode. With metal electrodes it is difficult to hold the electrode securely and at a uniform, precise distance to guide from the workpiece; this applies nament-Hch to smaller workpieces if the Current is comparatively weak and therefore the arc is short.
Die Erfindung betrifft ein Verfahren, bei dem die mit einer schmelzbaren Isoliermasse umhüllte Elektrode auf dem Werkstück in ganzer Länge der zu schweißenden bzw. zu lötenden Stelle (Naht) befestigt wird. Dabei erhält die Isolierhülle eine solche Dicke, daß die Metallelektrode durch sie in dem erforderlichen Abstande vom Werkstück gehalten wird.The invention relates to a method in which the with a fusible insulating compound encased electrode on the workpiece over the entire length of the to be welded or to soldering point (seam) is attached. The insulating sleeve is given such a thickness that the metal electrode is held by them at the required distance from the workpiece will.
In manchen Fällen wird man mehrere Elektroden nebeneinander parallel geschaltet benutzen, so daß mehrere Bogen entstehen, wobei die entstehenden Metallflüsse sich vereinigen. Die so erzeugte Lötstelle ist regelmäßiger als beim Arbeiten mit nur einer Elektrode. ■In some cases you will use several electrodes connected in parallel next to each other, so that several arches arise, whereby the resulting metal flows unite. The soldering point created in this way is more regular than when working with just one electrode. ■
In der beiliegenden Zeichnung gibt Fig. 1 in Seitenansicht, Fig. 2 im Querschnitt eine bildliche Darstellung des Verfahrens.In the accompanying drawing, FIG. 1 shows a side view, FIG. 2 shows a cross-section pictorial representation of the procedure.
Die beiden zusammenzulötenden Stücke a und b sind durch eine Klemmvorrichtung c zusammengespannt und mit einem Pol einer Wechselstromzuleitung verbunden. Die mit dem anderen Pol verbundene Elektrode d ist mit einem schmelzbaren Isoliermantel e überzogen. Dieser Überzug e kann beispielsweise aus Asbestfaden bestehen, die mit einer Masse, wie Natriumsilikat, Aluminiumsilikat u. dgl., bestrichen sind.The two pieces a and b to be soldered together are clamped together by a clamping device c and connected to one pole of an alternating current supply line. The electrode d connected to the other pole is covered with a fusible insulating jacket e . This coating e can for example consist of asbestos thread coated with a compound such as sodium silicate, aluminum silicate and the like.
Die Dicke der Isolierschicht e hängt von der Größe der Elektrode und der Stromstärke ab; je stärker der Strom, um so dicker die Schicht.The thickness of the insulating layer e depends on the size of the electrode and the current strength; the stronger the current, the thicker the layer.
Die Elektrode kann in verschiedener Weise auf dem Werkstück befestigt werden, beispielsweise durch Festbinden. Das Ende der Elektrode ist unbedeckt; der hier entstehende Lichtbogen schmilzt die Decke e ab und geht unter Wegschmelzen der Elektrodenmasse langsam die Lötnaht entlang. Die geschmolzene Deckmasse wirkt als Flußmittel und bewahrt das geschmolzene Metall davor, mit der Luft in Berührung zu kommen und porös zu werden. The electrode can be attached to the workpiece in various ways, for example by tying it down. The end of the electrode is uncovered; the resulting arc melts the cover e and slowly goes along the soldered seam, melting away the electrode compound. The molten cover mass acts as a flux and prevents the molten metal from coming into contact with the air and becoming porous.
