Description

Die Erfindung betrifft eine Stumpfschweißverbindung, bei: der die zu verschweißenden Teile in kleinem Abstand voneinander angeordnet sind und die so entstandene Schweißlücke durch ein Abdeckstück abgedeckt ist, das mit einem Steg in die Lücke hineinragt und das eine Aussparung aufweist, deren Breite größer als die Breite der Lücke ist, so daß die Rohrenden über einen Teil der Aussparung ragen. Durch diese Anordnung soll der Schweißvorgang erleichtert und die Rißbildung im Grunde der Schweißnaht verhindert werden.The invention relates to a butt weld connection in which: the parts to be welded are arranged at a small distance from each other and the the resulting weld gap is covered by a cover piece with a web protrudes into the gap and which has a recess whose width is greater than the width of the gap is such that the pipe ends protrude over part of the recess. This arrangement should facilitate the welding process and the formation of cracks in the Bases of the weld can be prevented.

Es hat sich aber gezeigt, daß die dicken Rippen der bekannten Ausführungen nicht gestatten; das gewünschte Ziel zu erreichen.But it has been shown that the thick ribs of the known designs not allow; achieve the desired goal.

Gemäß der Erfindung wird daher vorgeschlagen, den Steg aus mehreren nebeneinanderliegenden Rippen zu bilden. Diese Rippen können dabei gewindeartig verlaufen.According to the invention it is therefore proposed that the web from several to form adjacent ribs. These ribs can be thread-like get lost.

In der Zeichnung sind zwei Ausführungsbeispiele gemäß der Erfindung in zwei Abbildungen im Schnitt dargestellt.In the drawing are two embodiments according to the invention shown in section in two figures.

Die Enden i und 2 der zu verschweißenden Teile liegen in einem bestimmten Abstand. Ihre Stirnflächen sind abgeschrägt. Unter der Verbindungsstelle liegt das Abdeckstück 3 mit der Aussparung q. (Abb. i). Die Breite dieser Aussparung ist größer als der Abstand der Rohrenden, so daß diese die Seiten der Aussparung überdecken. Aus der Aussparung ragen Rippen 5 hervor und in den Zwischenraum zwischen die Rohrenden i und 2 hinein. Abb. 2 zeigt eine Ausführungsform für plattierte Rohre. Man erkennt, daB das Abdeckstück 3 auch mit dem Plattierungsmaterial versehen ist, jedoch nicht ganz bis zu den Rippen. An den Rohrenden i und 2 geht das Plattierungsmaterial auch nicht bis zu den Stirnflächen der Rohre, so daß eine Lücke 6 bestehenbleibt, die der Aussparung der Ausführung nach Abb. i entspricht.The ends i and 2 of the parts to be welded lie in a certain one Distance. Their faces are beveled. That is under the connection point Cover piece 3 with the recess q. (Fig.i). The width of this recess is larger than the distance between the pipe ends so that they cover the sides of the recess. Ribs 5 protrude from the recess and into the space between the pipe ends i and 2 into it. Fig. 2 shows an embodiment for clad tubes. One recognises, that the cover piece 3 is also provided with the plating material, but not all the way to the ribs. At the pipe ends i and 2 the cladding material also works not up to the end faces of the tubes, so that a gap 6 remains, the corresponds to the recess of the design according to Fig. i.
