Description
Die Erfindung betrifft einen elektrischen Lichtbogenschweißapparat, bei dem der Lichtbogen zwischen einer Elektrode und dem Werkstück gebildet und das Schweißgut dem Lichtbogen erst an der Schweißstelle oder in ihrer unmittelbaren Nähe zugeführt wird. Das Schweißgut hat dabei zweckmäßig die Form eines dünnen Drahtes, dessen Durchmesser von der Schweißstromstärke, der Größe der Schweißxo stelle und von anderen Einflüssen abhängt. Das Schweißgut wird durch besondere Nachschubvorrichtungen maschinell nach der gewünschten Stelle befördert.The invention relates to an electric arc welding apparatus in which the arc formed between an electrode and the workpiece and the weld metal the arc is only supplied at the welding point or in its immediate vicinity. The weld metal expediently has the shape of a thin one Wire, the diameter of which depends on the welding current, the size of the welding point and other influences. That Weld metal is machined by special feeding devices according to the desired Position promoted.
Nach der Erfindung wird als Kraftquelle für die Nachschubbewegung des Schweißgutes dieselbe Kraftquelle benutzt, die auch den Nachschub der Elektrode bewirkt. Dabei kann es erwünscht sein, die schwere Kraftquelle getrennt vom eigentlichen Schweißapparat anzuordnen. In solchen Fällen wird erfindungsgemäß die Bewegung vom Motor aus durch biegsame Wellen o. dgl. übertragen.According to the invention, the same is used as the power source for the feed movement of the weld metal Power source used, which also causes the electrode to be replenished. It can be desired be to arrange the heavy power source separately from the actual welding machine. In such cases, according to the invention, the movement from the motor is provided by flexible shafts or the like. Transferred.
In der Zeichnung ist schematisch angegeben, wie das Schweißen mit dem neuen Apparat eras folgt. Es bedeutet 11 das Werkstück, das aus zwei Blechen besteht, die an ihrer in der Zeichenebene liegenden vertikalen Stoßfuge miteinander verschweißt werden sollen. Die Schweißung erfolgt von unten nach oben. Der Lichtbogen 12 bildet sich zwischen dem Werkstück und der Elektrode 13 aus Kohle oder sonstigem geeigneten Material. Das Schweißgut 14 wird dem Lichtbogen an der Schweißstelle oder in ihrer unmittelbaren Nähe zugeführt. Es wird an seinem Ende infolge der Erwärmung durch den Lichtbogen abschmelzen, wobei sich der Schmelztropfen mit den flüssigen Teilen des Werkstückes verbindet und infolge der eAdhä- I sionskraft die vorhandene Fuge ausfüllt. Es bildet sich infolgedessen die Schweißnaht 15, die im unteren Teil der Zeichnung angedeutet ist.In the drawing it is shown schematically how the welding with the new device eras follows. 11 means the workpiece, which consists of two metal sheets which are to be welded to one another at their vertical butt joint lying in the plane of the drawing. The welding is done from bottom to top. The arc 12 is formed between the workpiece and the electrode 13 made of carbon or other suitable material. The weld metal 14 is fed to the arc at the welding point or in its immediate vicinity. It will melt at its end due to the heating by the arc, wherein the melt drops connects with the liquid parts of the workpiece, and as a result of e Adhä- I sion force the existing joint filling. As a result, the weld seam 15 is formed, which is indicated in the lower part of the drawing.
16 und 17 ist die Transportvorrichtung für das Schweißgut, das aus einem dünnen, auf der Trommel 18 als Magazin aufgewickelten Draht besteht. Die Transportvorrichtung wird erfindungsgemäß von demselben Motor angetrieben, der auch zum Antrieb der Elektrode 13 dient. Sie erhält an irgendeiner Stelle eine Rutschkupplung, die ein etwa vorkommendes Vorschieben des Schweißgutes über die Schweißstelle hinaus verhindert und die auch in Wirkung tritt, wenn das Schweißgut vorübergehend an dem Schweißstück festbacken sollte.16 and 17 is the transport device for the Weld metal consisting of a thin wire wound on the drum 18 as a magazine consists. According to the invention, the transport device is driven by the same motor, which also serves to drive the electrode 13. She receives one at some point Slipping clutch that prevents the weld metal from being pushed forward over the welding point also prevents and which also comes into effect when the weld metal is temporarily switched on should stick to the workpiece.
