Description

Elektrodendüse für die Elektro-Schlacke-Schweißung Die Erfindung betrifft eine Elektrodendüse für die Elektro-Schlacke-Schweißung, die innerhalb des Schweißspaltes angeordnet ist und zur Führung einer oder mehrerer Elektroden in das Schlackenbad dient. Die Erfindung besteht darin, daß die Düse, insbesondere zum Schweißen von Formprofilquerschnitten, etwa die Profilform der Werkstücke und eine entsprechende Anzahl von Kanälen zur Führung und Stromzuleitung der einzelnen Drahtelektroden aufweist, welche in an sich bekannter Weise gegebenenfalls auch vorgeheizt bzw. im geschmolzenen Zustand das Schlackenbad erreichen, und daß weiterhin die Düse ortsfest relativ zum Werkstück angeordnet ist und im Schlackenbad im Maß des Niveauanstieges abschmilzt.Electrode Nozzle for Electro-Slag Welding The invention relates to an electrode nozzle for electro-slag welding, which is located inside the welding gap is arranged and for guiding one or more electrodes into the slag bath serves. The invention consists in that the nozzle, in particular for welding Molded profile cross-sections, such as the profile shape of the workpieces and a corresponding one Number of channels for guiding and power supply of the individual wire electrodes has, which may also be preheated or preheated in a manner known per se. reach the slag bath in the molten state, and that continues to the nozzle Is arranged stationary relative to the workpiece and in the slag bath in the measure of the rise in level melts.

Es ist bekannt, die Elektrodendüsen so anzuordnen, daß sie automatisch mit dem ganzen Schweißgerät entsprechend dem Schweißfortschritt vorgeschoben werden. Das erfordert eine relativ kostspielige Automatik und mechanische Vorschubregelanordnungen.It is known to arrange the electrode nozzles so that they are automatic be advanced with the entire welding device according to the welding progress. This requires a relatively expensive automatic and mechanical feed control arrangements.

Die Erfindung bezweckt eine einfache und wirksame Anordnung ohne den üblichen Aufwand an Regeleinrichtungen für den Düsenvorschub usw.The invention aims at a simple and effective arrangement without the usual expenditure on control devices for the nozzle feed, etc.

Die erfindungsgemäße Düse wird an Hand eines Ausführungsbeispiels in der Zeichnung erläutert.The nozzle according to the invention is illustrated using an exemplary embodiment explained in the drawing.

In der Zeichnung ist ein Schema der Einrichtung zum elektrischen Schlackenbadschweißen unter Benutzung von Drahtelektroden als Zusatzwerkstoff dargestellt.In the drawing is a scheme of the device for electric slag pool welding shown using wire electrodes as filler material.

Zum Schweißen eines Formprofilquerschnittes 5 ; wird eine schmelzende Düse 6 angewendet, die mit Kanälen zum Vorschub des Zusatzwerkstoffes in Form von Draht, Stäben, Metallpulver oder flüssigem Metall versehen ist. Mit 8 ist das flüssige Schlackenbad und mit 10 das flüssige Metallschmelzbad bezeichnet. Mit dem Steigen des Schlackenbadniveaus schmilzt die Düse fortlaufend mit ab.For welding a shaped profile cross section 5; becomes a melting one Nozzle 6 applied, with channels for feeding the filler material in the form of Wire, rods, metal powder or liquid metal is provided. At 8 it's liquid Slag bath and 10 denotes the liquid molten metal bath. With the rise the level of the slag bath continuously melts the nozzle.
