Bisher setzte man beim Zusammenschweißen übereinandergelegter oder überlappter Metallstücke, z. B. Blechtafeln, Blechzylindern, Gitterwerken o. dgl., die mit Elektroden versehenen Pole zweier Stromleiter von beiden Seiten an das Schweißmaterial an, um den Strom an der betreffenden Schweißstelle hindurchzuleiten. Bei der Ausübung dieses Verfahrens ist man jedoch bei langen RöhrenPreviously, when welding together pieces of metal placed on top of one another or overlapped, z. B. sheet metal, sheet metal cylinders, latticework o. The like. That provided with electrodes Connect two electrical conductors from both sides to the welding material in order to transfer the current to the welding point in question to pass through. However, when practicing this procedure, one is with long tubes
ίο oder Platten, welche beispielsweise in ihrer Mitte geschweißt werden sollen, gezwungen, die Elektroden mittels langer leitender Arme an die Schweißstelle zu führen, was aber in bezug auf die Leitungslänge infolge desίο or plates, which for example in their Center to be welded, forced the electrodes by means of long conductive arms to lead to the welding point, but what in terms of the line length as a result of the
Spannungsveriustes bei der ohnehin schon geringen Spannung und der für den Druck der Schweißstelle nötigen Steifigkeit bei langen und dünnen Röhren oder großen Platten gar nicht oder nur sehr schwer ausführbar ist.Tension loss with the already low tension and that for the printing The required rigidity of the welding point cannot be implemented at all or only with great difficulty in the case of long and thin tubes or large plates is.
Aus diesem Grunde werden die Elektroden nach vorliegender Erfindung nicht mehr von verschiedenen Seiten sondern von derselben Seite an das Schweißmaterial angesetzt und auf der entgegengesetzten Seite mittels eines Hilfsleiters überbrückt.For this reason, the electrodes according to the present invention are no longer of different sides but attached to the welding material from the same side and bridged on the opposite side by means of an auxiliary conductor.
Auf der beiliegenden Zeichnung sind mehrere Ausführungsbeispiele der Erfindung veranschaulicht. Die Pole der beiden mit dem Transformator verbundenen Stromleiter α α werden von derselben Seite an das Schweißmaterial b angesetzt und durch einen losen Stromleiter c auf der anderen Seite vermittels des Schweißmaterials überbrückt, so daß bei Hindurchleitung des Schweiß-Stromes je nach Ausbildung der Pole an beiden oder an einem Pole sich Schweißstellen bilden.Several exemplary embodiments of the invention are illustrated in the accompanying drawing. The poles of the two current conductors α α connected to the transformer are attached to the welding material b from the same side and bridged by a loose current conductor c on the other side by means of the welding material, so that when the welding current is passed through, depending on the configuration of the poles on both or welds are formed on a pole.
Zur Hervorruf ung von Schweißstellen zwischen beiden Polen und dem Hilfgleiter ist Bedingung, daß die die Schweißstellen berührenden Flächen der beiden Pole gleich groß sind (Fig. 1). Wird jedoch nur eine Schweißstelle gewünscht, so erhält derjenige Pol, welcher eine Schweißung nicht herbeiführen soll, einen entsprechend größeren Querschnitt (Fig. 2).To create welds between both poles and the auxiliary glider it is a condition that the surfaces of the two poles touching the welds are the same are large (Fig. 1). However, if only one welding point is required, the one who receives it Pole, which should not cause a weld, a correspondingly larger one Cross section (Fig. 2).
Die Fig. 3 zeigt die Anwendung des vorliegenden Verfahrens z.B. zum Schweißen der Naht eines dünnen Rohres d. Die beiden P.ole α α sind hierbei gleichartig ausgebildet und besitzen gleich große Polflächen (Fig. 1), so daß zwei Schweißstellen entstehen. Der durch das Rohr d gesteckte Balken e aus nicht strom- oder stromleitendem Material ist der Träger des den Polen α α gegenüberstehenden HilfsleitersC Es ist hieraus ersichtlich, daß von der Länge des zu schweißenden Rohres nur die Länge des Balkens e abhängig ist, während die Leiter α α und c in jedem Falle unverändert bleiben können.FIG. 3 shows the application of the present method, for example for welding the seam of a thin pipe d. The two poles α α are designed in the same way and have pole faces of the same size (Fig. 1), so that two welds are created. The bar e inserted through the pipe d made of non-conductive or conductive material is the carrier of the auxiliary conductor C facing the poles α α. It can be seen from this that only the length of the bar e depends on the length of the pipe to be welded, Heads α and c can in any case remain unchanged.
