Description
Die Erfindung betrifft eine Einrichtung zur Stromzuführung bei der elektrischen Lichtbogenschweißung. Hierbei ist es häufig notwendig, den an das Werkstück fest angeschlossenen Pol von Zeit zu Zeit entsprechend der Fortbewegung der Schweißelektrode und der Fertigstellung der Schweißung in die Nähe der Schweißstelle zu verlegen, um eine Beruhigung des Lichtbogens herbeizuführen.The invention relates to a device for supplying power in electric arc welding. Here it is often necessary to adjust the pole permanently connected to the workpiece from time to time the advancement of the welding electrode and the completion of the weld in the To be relocated near the welding point in order to calm the arc.
Erwünscht ist bekanntlich eine geringe Ablenkung des Lichtbogens in der Schweißrichtung. Man hat ferner vorgeschlagen., den Stromanschluß auf dem Werkstück verschiebbar zu machen. Hierbei ergab sich aber der Nachteil, daß bei der Verschiebung eines entsprechend aufgelegten Kontaktteiles unter Spannung infolge der Unebenheiten oder der oxydischen Beschaffenheit der Oberfläche des Werkstücks Funkenbildungen auftreten, so daß auf dem Werkstück die Verschiebungsbahn des ruhenden Kontaktstückes infolge Verbrennungen u. dgl. sichtbar ist.It is known that a slight deflection of the arc in the welding direction is desirable. It has also been proposed that the power connector be slidable on the workpiece close. Here, however, there was the disadvantage that when moving a correspondingly placed contact part below Stress due to the unevenness or the oxidic nature of the surface of the Workpiece sparks occur, so that the displacement path of the stationary contact piece on the workpiece as a result Burns and the like is visible.
Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß neben dem verschiebbaren Stromanschluß ein oder mehrere an dem Werkstück fest angeklemmte Stromanschlüsse vorgesehen sind. Der verschiebbare Stromanschluß wird dann während der Schweißung derart bewegt, daß er in für die Lichtbogenführung passender Weise in der Nähe der Schweißelektrode steht. Ein Teil der Stromzuführung erfolgt dann über das oder die festen, Kontaktstücke. Im allgemeinen wird die Hauptmenge des Stromes aber über das bewegliche, dicht an der Schweißstelle liegende Kontaktstück fließen. Im Falle bei der Verschiebung des beweglichen Anschlußstückes dieses über unebene oder oxydierte Teile des Werkstückes bewegt werden muß, erhöht sich der Widerstand in diesemAccording to the invention, these disadvantages are avoided in that, in addition to the sliding Power connection one or more power connections firmly clamped to the workpiece are provided. The slidable power connector is then moved during the weld so that it is in for the Arc guide is appropriately close to the welding electrode. A part the power supply then takes place via the fixed contact piece (s). In general The main amount of the current is however via the moving one, close to the welding point lying contact piece flow. In the case of moving the movable connector If this has to be moved over uneven or oxidized parts of the workpiece, the resistance in this increases
