Description

Vorrichtung zur Elektro-Schlacke-Auftragsschweißung auf waagerechte Werkstückflächen mit Begrenzungsrahmen und Bandelektrode Zusatz zur Patentanmeldung K 38115 VIII d / 21 h (Auslegeschrift 1101653) Die Hauptpatentanmeldung K 38115 VIII d/ 21 h betrifft eine Vorrichtung zur Elektro-Schlacke-Auftragsschweißung auf etwa waagerecht liegende Werkstückflächen unter Verwendung eines gegenüber dem Werkstück verschiebbaren, mit wassergekühlten Wänden versehenen Begrenzungsrahmens für das flüssige Metall- bzw. Schlackenbad, bei der die Breite des Begrenzungsrahmens der Breite der gesamten aufzuschweißenden Werkstückfläche entspricht und der Rahmen während des Schweißens kontinuierlich waagerecht in Schweißrichtung bewegbar ist, wobei zwischen seiner in Schweißrichtung hinten liegenden Breitseite und der Werkstückoberfläche ein Spalt in Höhe der Dicke der Auftragsschicht vorgesehen ist und wobei eine abschmelzende Bandelektrode verwendet ist, die während des Schweißens von einer Bandspule abgewickelt wird, deren Breite der Gesamtbreite der aufzutragenden Werkstückfläche bzw. des Begrenzungsrahmens entspricht.Device for electro-slag build-up welding on horizontal workpiece surfaces with boundary frame and strip electrode Addition to patent application K 38115 VIII d / 21 h ( Auslegeschrift 1101653) The main patent application K 38115 VIII d / 21 h relates to a device for electro-slag build-up welding on approximately horizontal ones Workpiece surfaces using a boundary frame for the liquid metal or slag bath, which is provided with water-cooled walls and is displaceable relative to the workpiece, in which the width of the boundary frame corresponds to the width of the entire workpiece surface to be welded on and the frame can be continuously moved horizontally in the welding direction during welding, whereby a gap is provided between its broad side lying at the rear in the welding direction and the workpiece surface at the level of the thickness of the application layer and a consumable strip electrode is used, which is deviating from a strip reel during welding the width of which corresponds to the total width of the workpiece surface to be applied or the boundary frame.

Es hat sich gezeigt, daß unter Umständen eine riffelige Oberfläche des aufgetragenen Materials entsteht. Die vorliegende Erfindung bezweckt die Vermeidung solcher Oberflächenfehler, die in jenem Falle eine nachfolgende Bearbeitung notwendig machen. Die Erfindung besteht darin, daß die in Schweißrichtung gesehen hintere Breitseite des Begrenzungsrahmens aus einer gekühlten Walze besteht, die sich während der Relativbewegung zwischen Rahmen und Werkstück auf der Auftragsschicht abrollt und unterhalb ihrer Oberfläche Öffnungen, Bohrungen od. dgl. für die Durchleitung des flüssigen Kühlmittels aufweist.It has been shown that under certain circumstances a corrugated surface of the applied material is created. The present invention aims at avoidance such surface defects, which in that case require subsequent processing do. The invention consists in that the rear as seen in the welding direction The broad side of the bounding box consists of a cooled roller that extends during the relative movement between the frame and the workpiece rolls on the application layer and below its surface openings, bores or the like for the passage of the liquid coolant.

Neben der Glättung der Oberfläche der Auftragsschicht dient die Walze dazu, das Schlackenbad in der Umgebung der Elektrode zu halten. Die Walze kann aus einem die Wärme gut leitenden Material, z. B. Kupfer, bestehen.In addition to smoothing the surface of the application layer, the roller is used to keep the slag bath in the vicinity of the electrode. The roller can go out a material that conducts heat well, e.g. B. copper exist.
