PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf das Erhitzen und Schweifsen mit Hülfe des elektrischen Lichtbogens, wobei das Werkstück den einen und ein Kohlenstift den anderen Pol bildet.The present invention relates to electrical heating and welding Arc, with the workpiece at one pole and a carbon pin at the other forms.
In vielen Fällen ist es nothwendig oder wünschenswerth, beide Seiten des Werkstückes gleichzeitig zu erhitzen oder in einer Hitze eine Schweifsstelle (von beträchtlicher Länge herzustellen, und es ist schwierig, ja sogar häufig unmöglich, dies mit einem einzigen Lichtbogen zu bewerkstelligen- Andererseits hat es sich bisher als unmöglich erwiesen, zwei oder mehrere Lichtbogen gleichzeitig anzuwenden. ·In many cases it is necessary or desirable to heat both sides of the workpiece at the same time or to produce a weld joint ( of considerable length in one heat, and it is difficult, even often impossible, to do this with a single arc) previously proven impossible to use two or more arcs at the same time.
Nach vorliegender Erfindung erzielt man dies in folgender Weise: Alle Kohlenstifte bind mit einer der von der Stromquelle ausgehenden Hauptleitungen, z. B. der negativen, verbunden, während die andere Hauptleitung, z. B. die positive, mit dem Werkstück verbunden ist. Um zu vermeiden, dafs die Stromschwankungen in dem einen Bogen die Stetigkeit der übrigen Lichtbögen beeinflussen, schaltet man zwischen jeden Kohlenstift und die Hauptleitung einen geeigneten Widerstand ein.According to the present invention, this is achieved in the following way: All carbon sticks bind to one of the main lines coming from the power source, e.g. B. the negative, connected while the other main line, z. B. the positive, is connected to the workpiece. In order to avoid the current fluctuations affect the continuity of the remaining arcs in one arc, a suitable resistor is connected between each carbon pin and the main line.
Die Zeichnung zeigt eine schematische Darstellung der Erfindung.The drawing shows a schematic representation of the invention.
A ist die mit dem negativen Pol der Stromquelle verbundene Hauptleitung. B ist die mit dem positiven Pol verbundene Hauptleitung. C C sind Stifte — gewöhnlich aus Kohle A is the main line connected to the negative pole of the power source. B is the main line connected to the positive pole. C C are pens - usually made of charcoal
die durch Drähte D D mit derthose through wires DD with the
Hauptleitung A verbunden sind; die Drahte D enthalten Widerstände EE. F ist ein Rohr, an welches der Flantsch G angeschweifst werden soll. Dieses Rohr ist mit der Hauptleitung B verbunden und an einer nicht gezeichneten Drehbank angeordnet und dreht sich, wobei' die Lichtbögen auf die Verbindungsstelle einwirken.Main line A are connected; the wires D contain resistors EE. F is a pipe to which the flange G is to be gripped. This tube is connected to the main line B and arranged on a lathe, not shown, and rotates, with the arcs acting on the connection point.
