Abstract
Description
Das in England neu entwickelte Schweißverfahren unter der Bezeichnung "Friction Stir Welding" (EP 0615480 B1 und EP 0752926 B1), in Deutschland als Rührreib schweißen oder Reibrührschweißen bekannt, erlaubt es über eine "teigige" Naht die mit Spalt "Null" aufeinander gedrückten Werkstücke zu verbinden. Dieser Zustand wird durch die kontinuierliche Bewegung eines drehendes Werkzeugs erreicht. Das Werk zeug besteht aus einem Stift und einer Schulter. Die Schulter verhindert den Verlust des durch den Stift ausgepreßten Materials. Dadurch bildet sich eine Naht aus, die ähnlich der konventionellen Schmelzschweißnaht aussieht. Das Schweißverfahren setzt nach der Anfangsphase eine stationäre Phase voraus, in der die Prozeß- und Verfahrensparameter, wie z. B. die Werkzeugumdrehungen, der Drehemoment, die Schweißgeschwindigkeit, die Werkzeugreibkraft sowie die Preßkraft, möglichst konstant gehalten werden. Durch das Schweißen tritt eine Entfestigung des Werkstoffs im Schweißnahtbereich auf. Auch die Ergebnisse von Schwingversuchen einiger Schweißungen aus AL-Legierungen liegen im Bereich der WIG- bzw. MIG geschweißten Verbindungen (Krüger, U.: Rührreibschweißen von Aluminium, Braunschweig-Kolloquium, 29. Oktober 1999, 8 Seiten).The welding process newly developed in England under the name "Friction Stir Welding "(EP 0615480 B1 and EP 0752926 B1), in Germany as an agitator welding or friction stir welding known, it allows the "pasty" seam to connect workpieces pressed together with gap "zero". This condition will achieved by the continuous movement of a rotating tool. The work Stuff consists of a pen and a shoulder. The shoulder prevents loss of the material squeezed out by the pen. This creates a seam that looks similar to the conventional fusion weld. The welding process requires a stationary phase after the initial phase, in which the process and Process parameters, such as. B. the tool revolutions, the torque, the Welding speed, the tool friction force and the pressing force, if possible be kept constant. The welding causes a softening of the material in the weld area. The results of vibration tests by some AL alloy welds are in the range of TIG and MIG welded connections (Krüger, U .: friction stir welding of aluminum, Braunschweig Colloquium, October 29, 1999, 8 pages).
Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zu Grunde, die mechanisch-technologischen Werte der Schweißverbindungen und insbesondere die Ermüdungsfestigkeit zu verbessern.The invention specified in claim 1 is based on the problem that mechanical-technological values of the welded joints and especially the Improve fatigue strength.
Die Verbesserung der mechanisch-technologischen Eigenschaften wird durch das im Patentanspruch 1 der Erfindung aufgeführte Schweißverfahren und im Patent anspruch 2 der Erfindung aufgeführten Mitteln erreicht. Die zwangsläufig erzeugten Bewegungen (Impulse) verformen die Schweißnaht, "verdichten" und verfestigen sie. Die Struktur des Werkstoffs wird durch das "Hämmern" im Bereich der Schweißnaht verfeinert.The improvement of the mechanical-technological properties is achieved by the Claim 1 of the invention listed welding method and in the patent Claim 2 of the invention achieved means. The inevitably generated Movements (impulses) deform the weld seam, "condense" and solidify it. The structure of the material is made by "hammering" in the area of the weld refined.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die mit diesem Schweißverfahren hergestellten Verbindungen verbesserte mechanisch- technologische Eigenschaften besitzen. Dadurch ergib sich eine Erhöhung der Lebensdauer und der Sicherheit von solchen Schweißkonstruktionen.The advantages achieved by the invention are, in particular, that the connections made using this welding process improved mechanical possess technological properties. This results in an increase in Lifetime and safety of such welded structures.
Einige Ausführungsmöglichkeiten der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben.Some possible embodiments of the invention are shown in the drawing and are described in more detail below.

Als wichtigeres Beispiel stellt sich die vertikale Bewegung des Werkzeuges dar. Durch die impulsive zeitliche Veränderung der Preßkraft wird während des Schweißens der Werkstoff unter der Schulter des Werkzeugs "gehämmert". Die im Werkstück erzeugte plastische Verformung verfeinert die Nahtstruktur und verfestigt sie, was sich positiv auf die Erhöhung der mechanisch-technologischen Eigenschaften und insbesondere der Ermüdungsfestigkeit auswirkt.The vertical movement of the tool is a more important example the impulsive change in the pressure force over time is during welding Material "hammered" under the shoulder of the tool. The generated in the workpiece plastic deformation refines the seam structure and solidifies it, which has a positive effect the increase in the mechanical-technological properties and in particular the Fatigue resistance affects.
