Abstract

A linear weld joint is produced by moving a rotating friction stud (1) along the gap between overlapping workpieces (2, 3) so that the overlapping material is made plastic by the frictional heat and is intimately merged by the material transport effect of the rotation. An Independent claim is also included for a stud which is used in the above process and which has a spherical, hemispherical or parabolic design.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer linienförmigen Schweißverbindung zwischen zwei oder mehreren Werkstücken mittels eines rotierenden Reibbolzens. Insbesondere ein Verfahren zur Herstellung einer Verbindung, bei der mindestens ein Werkstück 1 an der Fügestelle einen dünnwandigen Querschnitt aufweist.The invention relates to a method for producing a linear weld connection between two or more workpieces by means of a rotating friction pin. In particular, a method for producing a connection, in which at least one workpiece 1 has a thin-walled cross section at the joint.

Es sind bereits unterschiedliche Verbindungstechniken zur Herstellung von Linienschweißverbindungen bekannt. In der heutigen Fertigungstechnik haben sich bei Dünnblechen insbesondere die MIG und MAG-Schweißverbindungen durchgesetzt.There are already different connection technologies for the production of Line weld connections known. In today's manufacturing technology have become Thin sheets in particular the MIG and MAG welded joints.

Bei den heute verstärkt aufkommenden Materialien, wie z. B. Alu und Magnesium stellt das Fügen mittels eines rotierenden Reibbolzens eine wesentliche Verbesserung dar.With today's increasingly emerging materials such. B. Aluminum and magnesium Joining using a rotating friction pin is a significant improvement.

Es lassen sich erhebliche Verbesserungen der Qualität in Bezug auf die Festigkeit, der Verwendung unterschiedlicher Materialkombinationen sowie der optischen Eigenschaft erzielen. Materialvorbereitung und der Einsatz von Zusatzwerkstoffen sind nicht erforderlich.There can be significant improvements in quality in terms of strength, which Use of different material combinations and the optical property achieve. Material preparation and the use of additional materials are not necessary.

Der Anmeldung liegt die Aufgabe zugrunde, ein Verfahren zum Linienschweißen so zu entwickeln, daß es möglich ist Bleche aus gleichen und unterschiedlichen Werkstoffen fest, schnell, zuverlässig und kostengünstig zu verbinden. The registration is based on the task of a method for line welding develop that it is possible to make sheet metal from the same and different materials, to connect quickly, reliably and inexpensively.  

Erfindungsgemäß wird diese Aufgabe durch die Merkmale 1 gelöst, bei der ein rotierender Bolzen (siehe Fig. 1) entlang der Kehle von zwei oder mehreren überlappend liegenden Werkstücken (vorzugsweise Bleche) bewegt wird, und zwar so, daß die übereinander liegenden Werkstücke über die Reibungswärme plastifiziert werden. Der durch die Rotation hervorgerufene Materialtransport führt zu einem innigen Ineinanderfließen der plastifizierten Materialien, so daß sich hinter dem rotierendem Bolzen eine Kehlnaht (ähnlich wie die von herkömmlichen Schmelzschweißverbindung) bildet.According to the invention, this object is achieved by features 1, in which a rotating bolt (see FIG. 1) is moved along the throat of two or more overlapping workpieces (preferably sheets), in such a way that the workpieces lying one above the other via the frictional heat be plasticized. The material transport caused by the rotation leads to an intimate flow of the plasticized materials so that a fillet weld (similar to that of conventional fusion welded joints) forms behind the rotating bolt.

Im Unterschied zum herkömmlichen Schmelzschweißen kommt das Material für die Kehlenaht aber nicht aus einem Schweißzusatzwerkstoff, sondern aus den zu fügenden Materialien selbst.In contrast to conventional fusion welding, the material for the fillet weld comes but not from a filler metal, but from the materials to be joined themselves.

Die Optimierung der Schweißnaht erfolgt durch die Wahl einer geeigneten Geometrie (Kugelform) und Werkstoff (Wolfram) des Reibbolzens, seiner Positionierung sowie der Wahl der Drehzahl, der Zustell- und der Vorschubgeschwindigkeit.The welding seam is optimized by choosing a suitable geometry (Spherical shape) and material (tungsten) of the friction pin, its positioning and the choice the speed, the feed and the feed speed.

Vorteilhaft ist eine kugel- bzw. halbkugelförmige Gestaltung des Reibbolzens sowie eine schräge Führung des Bolzens (siehe Fig. 2). Dadurch wird für ein gleichmäßiges Auslaufen der Schweißnaht hinter dem Bolzen gesorgt. Die Schweißqualität wird damit sowohl optisch als auch festigkeitsmäßig optimiert. A spherical or hemispherical design of the friction pin and an oblique guidance of the pin are advantageous (see FIG. 2). This ensures that the weld seam runs out evenly behind the stud. The welding quality is thus optimized both visually and in terms of strength.
