Description

Zum autogenen Schweißen von Metallen werden bisher Schweißstäbe von rundem Querschnitt verwendet. Bei diesen Schweißstäben findet infolge ihres kreisförmigen Querschnittes die zum Schmelzen des Stabes erforderliche Schweißflamme dieselbe Angriffsfläche, gleichgültig, wie man den runden Stab drehen mag.Up to now, round welding rods have been used for oxy-fuel welding of metals Cross section used. These welding rods are due to their circular shape Cross-section, the welding flame required to melt the rod has the same attack surface, no matter how you turn the round stick.

ao längere Zeit an die Schweißstelle halten, um die erforderliche Materialabgabe des Stabes zu bekommen. Dadurch ist es oft erforderlich, den Schweißstab und das Werkstück besonders lange zur Materialabgabe der Einwirkung der Flamme zu unterwerfen. Nun ist es bekannt, daß besonders beim Schweißen von Gußeisen die Flammeneinwirkung von möglichst kurzer Dauer sein soll, um ein Ausdampfen des Kohlenstoffes zu verhindern und die Schweißstelle weich zu erhalten. Eine starke Flammeneinwirkung läßt sich nun vermeiden, wenn man einen Schweißstab nehmen kann, welcher der Ein- ! wirkung der Flamme verschieden große Anj griffsflächen bietet, damit je nach Wunsch 3S j verschieden viel Material an die Schweißstelle abgegeben werden kann. Nach vorliegender Erfindung nimmt man nun zur Erreichung dieses Zweckes am vorteilhaftesten einen Schweißstab, welcher einen ovalen Querschnitt besitzt. Je nach der Drehung1 des Schweißstabes kann ein derartiger Stab der einwirkenden Flamme verschieden große Angriffsflächen bieten. Dadurch wird der Schweißstab einmal mehr und einmal weniger Material an die zu schweißende Stelle abgeben können.ao hold at the welding point for a long time in order to get the required material release of the rod. As a result, it is often necessary to subject the welding rod and the workpiece to the action of the flame for a particularly long time in order to release material. It is now known that, particularly when welding cast iron, the flame action should be as short as possible in order to prevent the carbon from evaporating and to keep the weld point soft. A strong flame effect can now be avoided if you can use a welding rod, which is the one! can be reached effectively faces the flame of different sizes Anj offers so as desired 3 S j different amounts of material at the weld made. According to the present invention, in order to achieve this purpose, it is most advantageous to use a welding rod which has an oval cross-section. Depending on the rotation 1 of the welding rod, such a rod can offer attack surfaces of different sizes to the acting flame. As a result, the welding rod will be able to release more and less material to the point to be welded.

Die Erfindung ist in der Zeichnung dargestellt, und zwar zeigen:The invention is shown in the drawing, namely show:

Fig. ι und 2 eine Ansicht und einen Schnitt eines Schweißstabes von ovalem Querschnitt. Beim Gebrauch des neuen Schweißstabes ist es nicht nötig, daß man die Flamme bei einer gewünschten größeren Materialabgabe länger als sonst auf den Schweißstab und die Schweißstelle einwirken läßt. Man braucht nur den Schweißstab so zu drehen, daß er der Flamme die größere Angriffsfläche gibt. Die Ausdampfung des Kohlenstoffes ist daher beim Gebrauch der ovalen Schweißstäbe bedeutend geringer. Außerdem spart man mit den neuen Schweißstäben beträchtliche Zeit, denn man braucht den neuen Schweißstab bei- großen Sehweißstellen nicht länger aufFig. Ι and 2 a view and a section a welding rod of oval cross-section. When using the new welding rod it is not necessary to open the flame when a larger material release is desired Let act longer than usual on the welding rod and the welding point. You need just turn the welding rod in such a way that it gives the flame the larger surface it can attack. The evaporation of carbon is therefore important when using the oval welding rods less. In addition, you save considerable time with the new welding rods, because you need the new welding rod with large areas of vision no longer open
