SchweißverfahrenWelding process
Die vorliegende Erfindung betrifft das Schweißen und insbesondere ein Verfahren zum stumpfen Zusammenschweissen von Rohrenden.The present invention relates to welding and in particular a method for butt welding together pipe ends.
Es ist bekannt, verbrauchbare Einsätze für die Wurzelnaht der Stumpfschweißsteilen von Rohren einzusetzen. Die verbrauchbaren Einsätze müssen auf Länge zugeschnitten werden, in Ringe mit dem geforderten Durchmesser geformt werden und an die Rohre angepaßt werden. Dies lanii ein zeitraubender und schwieriger Vorgang sein.It is known to use consumable inserts for the root seam of the butt weld parts of pipes. The consumable inserts must be cut to length, formed into rings of the required diameter and adapted to the pipes. This lanii can be a time consuming and difficult process.
Gemäß der vorliegenden Erfindung weist ein Verfahren zum stumpfen Zusammenschweißen von Rohrenden die Merkmale auf, einen Ring aus Schweißmaterial vorzusehen, der am radial inneren Abschnitt des Ringes Endflächen ,aufweist, Rohrenden mit Flächen auszubilden, die komplementär zu den profilierten Endflächen des Ringes sind, Einsetzen des Ringes zwischen die Rohrenden, Zusammenbrin'-gen der Rohrenden, um den Ring zwischen diesen zu halten, wobei ein radial äußerer Abschnitt des Ringes die Rohrenden umgibt, und Schmelzen des Ringes, um dieAccording to the present invention, a method for butt welding pipe ends together has the features to provide a ring of weld material having end faces on the radially inner portion of the ring, Form pipe ends with surfaces that are complementary to the profiled end surfaces of the ring, inserting of the ring between the pipe ends, bring them together of the pipe ends to hold the ring between them, a radially outer portion of the ring being the Surrounding pipe ends, and melting the ring to the

Rohrenden stumpf zusammenzuschweißen.Butt weld pipe ends together.
Bevorzugt weist das Verfahren die Ausbildung des Ringes mit einem Innendurchmesser , der im wesentlichen gleich ist dem Innendurchmesser der Rohrenden and die Bildung eines Falzes in jeder Endfläche des Ringes an dessen Innenumfang auf, um Sitze für die jeweiligen Rohrenden zu bilden. Bequemerweise ist der radial außenliegende Abschnitt des Ringes, der die Rohrenden umgibt, im Querschnitt dreieckig. Preferably, the method includes forming the ring with an inside diameter that is substantially the same is the inside diameter of the pipe ends and the formation of a fold in each end face of the ring on its inner circumference to form seats for the respective pipe ends. Conveniently, the radially outer portion of the ring surrounding the pipe ends is triangular in cross-section.
Die Erfindung wird beispielsweise unter Bezugnahme auf die beigefügten Zeichnungen noch weiter beschrieben; in diesen zeigt:The invention will be further described, for example, with reference to the accompanying drawings; in this shows:
Fig. 1 im Schnitt einen Schweißring, der zwischen den Enden zweier Rohre angeordnet ist, undFig. 1 shows in section a welding ring which is arranged between the ends of two tubes, and
Fig. 2 die Darstellung eines Schnitts längs Linie A-A in Fig. 1.FIG. 2 shows a section along line A-A in FIG. 1.
Ein Schweißring 1 ist mit Falzen oder Aussparungen 2 und 3 in seinen jeweiligen Endflächen ausgebildet. Die Rohrenden 4 und 5, die eine komplementär-rechteckige Kantenvorbearbeitung auf weisen, passen in die Falze oder Aussparungen 2 und 3. Der Innendurchmesser des Ringes ist im wesentlichen gleich dem Innendurchmesser der Rohrenden und der Durchmesser eines jeden Falzes oder einer jeden Aussparung ist im wesentlichen gleich und jedenfalls nicht kleiner als der Außendurchmesser des jeweiligen Rohrendes. Jener Abschnitt des Ringes 1, der das Rohrende umgibt, ist bevorzugt im Querschnitt dreieckig, wobei der Scheitel 6 des Dreiecks auf der Symmetrie-Querebene liegt. Obwohl der Außenabschnitt des Ringes andere Profile aufweisen kann, beispielsweise ein halbkreisförmiges, ist ein dreieckiger Querschnitt vor-A welding ring 1 is formed with folds or recesses 2 and 3 in its respective end faces. The pipe ends 4 and 5, which have a complementary rectangular edge preprocessing, fit into the folds or recesses 2 and 3. The inner diameter of the ring is essentially the same as the inner diameter of the pipe ends and the diameter of each fold or recess is substantially the same and anyway not smaller than the outer diameter of the respective pipe end. That section of the ring 1, which the Surrounding the pipe end is preferably triangular in cross section, with the apex 6 of the triangle on the transverse plane of symmetry lies. Although the outer portion of the ring may have other profiles, for example a semicircular, a triangular cross-section is pre-
teilhaft, da der Scheitel 6 einen optischen Bezug entweder für das Schweißen von Hand oder für die Positionierung eines Umlauf-Schweißkopfes aufweist, um das Verschmelzen des Ringes mit den Rohrenden zu bewirken. Eine Einspannvorrichtung oder eine Abstützung kann vorgesehen sein, um während der Schweißtätigkeit die Rohrenden in den Aussparungen oder Falzen zu halten. Anfangs können die Rohrenden voneinander getrennt gehalten werden, und der Schweißring wird auf das Ende eines der Rohre dadurch passend aufgesetzt, daß man dieses Ende in den Falz oder die Aussparung in der einen Endfläche des Ringes einsetzt. Das Ende des anderen Rohres wird dann so bewegt, daß es im Falz oder in der Aussparung in der anderen Endfläche des Ringes sitzt. Der Ring wird hierbei in seiner Lage ortsfest gehalten, um einem Arbeiter genug Freiraum zur Durchführung der Schweißarbeit einzuräumen.part because the apex 6 is an optical reference either for welding by hand or for positioning of a rotary welding head to the To effect fusion of the ring with the pipe ends. A jig or support can be provided to hold the pipe ends in the recesses or folds during welding. At first the pipe ends can be kept separate from each other, and the weld ring is attached to the end of a of the pipes by fitting this end into the rebate or recess in one end face of the ring begins. The end of the other tube is then moved so that it is in the fold or in the recess seated in the other end face of the ring. The ring is held stationary in its position for a worker Allow enough space to carry out the welding work.
Als Alternativlösung kann der Ring auch einen rautenförmigen Querschnitt aufweisen, der dazu eingerichtet ist, in einem komplementär ausgebildeten Kanal zu sitzen, der durch Auskehlen oder Abschrägen der Rohrenden gebildet ist. Bei einer solchen Anordnung sitzt der Ring anfangs im Kanal, wobei die benachbarten Enden der Röhre nur den Abstand von einem kleinen Spalt zueinander aufweisen. Der obere dreieckige Abschnitt des im Schnitt rautenförmigen Ringes umgibt die Rohrenden, wobei der Scheitel des Dreiecks im wesentlichen in der Symmetrie-Querebene liegt. Wie bereits vorher, ist es für eine Bedienungsperson nur erforderlich, den Ring zu schmelzen, um eine Schweißstelle über die Wandstärken des Rohres hinweg zu verschweißen.As an alternative, the ring can also be a diamond-shaped one Have cross-section which is set up to sit in a complementary channel, which is formed by grooving or chamfering the pipe ends. In such an arrangement, the ring is seated initially in the channel, with the adjacent ends of the tube only a small gap apart. The upper triangular section of the ring, which is diamond-shaped in section, surrounds the pipe ends, the The vertex of the triangle lies essentially in the transverse plane of symmetry. As before, it's for one Operator only required to melt the ring to create a weld over the wall thickness of the pipe weld away.
Das Material des Schweißringes wird so gewählt, daß es mit dem Material der Rohre kompatibel und mühelos hiermit verschweißbar ist, welches rostfreier Stahl sein kann.The material of the welding ring is chosen so that it is compatible and effortless with the material of the pipes can be welded to it, which can be stainless steel.
Der Ring 1 ist imstande, in einem einzigen Durchgang geschmolzen zu werden, um all das erforderliche Füllmaterial zur Fertigstellung einer Verbindung zu liefern, welche sowohl eine hinlängliche Eindringung des Schweißnahtbodens als auch eine Verstärkung durch die Schweißstelle liefert.The ring 1 is capable of being melted in a single pass to remove all the required filler material to complete a joint that has both sufficient penetration the bottom of the weld seam as well as reinforcement by the weld point.
Die Verwendung vorgeformter Schweißringe für Stumpfschweißvorgänge führt zu einer Anzahl von Vorzügen gegenüber herkömmlichen Techniken. Diese Vorzüge sind, kurz gesagt:The use of preformed welding rings for butt welding results in a number of advantages over conventional techniques. These virtues are in a nutshell:
1. Mühelose Vorbereitung des Rohres und müheloses Einpassen der Verbindung,1.Effortless preparation of the pipe and effortless fitting of the connection,
2. das Vermeiden einer Änderung der Schweißbarkeit von Schmelzvorgang zu SchmelzVorgang,2. avoiding a change in weldability from melting process to melting process,
3. die Verwendung vereinfachter Umlauf-Schweißköpfe3. the use of simplified rotary welding heads
(Schweißdrahtnachführung und automatische S chwe iß -lichtbogen- Spannungsregelung sind nicht erforderlich),(Welding wire tracking and automatic welding arc voltage regulation are not required),
4. es kann von Hand geschweißt werden,4. it can be welded by hand,
5. Vermeiden negativer Läuterungssysteme an Rohren mit großem Durchmesser, und5. Avoid negative refining systems on large diameter pipes, and
6. Vereinfachung der Röntgenuntersuchung infolge der Gleichförmigkeit der Schweißung.6. Simplification of the X-ray examination due to the uniformity of the weld.
