Description
Anordnung zum gleichzeitigen Widerstands-Buckelschweißen von drei Schweißteilen Die Erfindung betrifft eine Anordnung zum gleichzeitigen Widerstands-Buckelschweißen von drei Schweißteilen mit unterschiedlicher Wandstärke oder verschiedener elektrischer Leitfähigkeit, bei der die Buckel ausschließlich am mittleren Schweißteil, und zwar auf der einen Seite größer als auf der anderen, jedoch jeweils untereinander gleich groß, angeordnet sind.Arrangement for resistance projection welding of three at the same time Weldments The invention relates to an arrangement for simultaneous resistance projection welding of three weldments with different wall thicknesses or different electrical Conductivity at which the hump is exclusively on the central welding part, namely larger on one side than on the other, but equal to each other large, are arranged.
Hierbei treten oft Schwierigkeiten und Fehlschweißungen infolge Durchbrennens der dünnwandigen Schweißteile auf, d. h. daß beispielsweise die Schweißstelle an dem starkwandigen Teil gut, dagegen die Schweißstelle an dem schwachwandigen Teil zu Beanstandungen Anlaß gibt.Difficulties and faulty welds as a result of burning through often occur here the thin-walled weldments, d. H. that, for example, the weld the thick-walled part is good, but the weld on the weak-walled part gives cause for complaint.
Es ist bereits bekannt, an dem Mittelteil Buckel verschiedener Größe anzubringen, und zwar auf der einen Seite größer als auf der anderen, wobei jeweils die Buckel untereinander gleich groß sind. Bei diesen bekannten Buckelverbindungen soll jedoch die dem dünneren Werkstück zugewandte Fläche des Mittelteiles eine größere Gesamtbuckelfläche aufweisen als die andere, um den Widerstand klein zu halten. Auch ist die Anzahl der Buckel auf beiden Seiten in diesem Falle gleich groß.It is already known to have humps of various sizes on the middle part to be attached, on one side larger than on the other, with each the humps are equal to each other. With these known hump connections however, the surface of the central part facing the thinner workpiece should have a larger one Have total hump area than the other in order to keep the resistance small. The number of humps on both sides is also the same in this case.
Die Erfindung besteht darin, daß die Anzahl der kleineren Buckel größer gewählt ist als die der großen Buckel und daß die kleineren Buckel dem dünnwandigen Schweißteil bzw. dem Schweißteil mit der besseren elektrischen Leitfähigkeit zugeordnet sind und daß die Volumina der Schweißlinsen bzw. die verschweißten Buckelquerschnittsflächen der großen Buckel insgesamt etwa gleich denen der kleineren Buckel insgesamt sind.The invention consists in that the number of smaller humps is greater is chosen as that of the large hump and that the smaller hump is the thin-walled one Welding part or the welding part with the better electrical conductivity assigned and that the volumes of the weld nuggets or the welded projection cross-sectional areas of the large humps as a whole are roughly the same as those of the smaller humps as a whole.
In der Zeichnung ist ein Ausführungsbeispiel nach der Erfindung schematisch dargestellt.An exemplary embodiment according to the invention is shown schematically in the drawing shown.
Die beispielsweise aus Stahl bestehenden Schweißteile in Form der Bleche 1, 2 und 3 sollen durch Buckelschweißen miteinander verbunden werden. Dabei soll die Blechstärke der Bleche 1 und 2 zu je 3 mm und die Blechstärke des Bleches 3 zu 1 mm angenommen werden. Das mittlere Blech 2 ist an der dem starken Blech 1 zugewandten Seite mit dem Buckel 4 und an der dem schwächeren Blech 3 zugewandten Seite mit den Buckeln 5 und 6 versehen. Die Buckelquerschnittsflächen der Buckel 4 bzw. deren Schweißlinsenvolumen sind insgesamt etwa gleich den Querschnittsflächen bzw. den Volumina der beiden Buckel 5 und 6 zusammen. Auf diese Weise wird erreicht, daß durch den Buckel 4 der gesamte Schweißstrom J fließt, während durch die Buckel 5 und 6 nur noch die Ströme J, und J2 fließen, die im vorliegenden Falle nur noch halb so groß sind wie der Gesamtschweißstrom J.The welded parts, for example made of steel, in the form of Sheets 1, 2 and 3 are to be connected to one another by projection welding. Included the sheet thickness of sheets 1 and 2 should be 3 mm each and the sheet thickness of the sheet 3 to 1 mm can be assumed. The middle sheet 2 is on the thick sheet 1 facing side with the boss 4 and on the weaker sheet 3 facing Provide the side with the humps 5 and 6. The hump cross-sectional areas of the humps 4 or their nugget volume are overall approximately equal to the cross-sectional areas or the volumes of the two humps 5 and 6 together. In this way it is achieved that the entire welding current J flows through the projection 4, while through the projection 5 and 6 only the currents J, and J2 flow, which in the present case only are half as large as the total welding current J.
Zum besseren Verständnis sind im vorstehenden Ausführungsbeispiel lediglich drei Buckel dargestellt; sinngemäß kann die Anzahl der Buckel jedoch entsprechend der Stromstärke erhöht werden. Ebenso kann die Anzahl der Buckel auch in Abhängigkeit von der elektrischen Leitfähigkeit der Schweißteilwerkstoffe bestimmt sein.For a better understanding are in the above embodiment only three humps shown; however, the number of humps can be analogous accordingly the amperage can be increased. Likewise, the number of humps can also be dependent be determined by the electrical conductivity of the weldment part materials.
