Das Zusammenschweißen von drei Blechlagen mittels Widerstandschweißung in einem Arbeitsgang bereitet erhebliche Schwferigkeiten. Die Schweissung gelingt nur dann, wenn mit einem hohen Elektrodendruck geschweißt wird« Ein hoher Elektrodendruck erfordert aber automatisch höhere Schweißleistung. Ein starkes Verwerfen der Oberfläche des Schweißpunktes ist durch den höheren Druck und die größere Wärme die unabwendbare Folge.The welding together of three sheet metal layers by means of resistance welding in one operation causes considerable difficulties. The welding only succeeds if welding is carried out with a high electrode pressure «However, a high electrode pressure automatically requires higher welding performance. A strong warping of the surface of the welding point is the inevitable consequence due to the higher pressure and the higher heat.
Durch die Erfindung sollen die genannten lachteile bei einer Zusammenschweißung von mindestens drei Blechlagen durch eine entsprechende Ausbildung des mittleren Bleches vermieden werden, indem neuheitsgemäß auf jeder Seite des Bleches je zwei symmetrisch und dicht beieinander angeordneteBuckel vorgesehen sind, so daß die vier dicht beieinanderliegenden Buckel eine Warzenschweißung ergeben. Zweckmäßig sind die beiden Buckel jeder Seite kreuzförmig zueinander gelegt. Die Erfindung erfordert einen geringeren Elektrodendruck und eine entsprechend geringere Schweißleistung, wobei eine großflächige Elektrode Verwendung finden kann. Die Oberfläche der beiden äußeren Bleche zeigt am Schweißpunkt nur geringe Verwerfungen.The aim of the invention is to said disadvantageous parts when welded together of at least three sheet metal layers can be avoided by appropriately designing the middle sheet by novelty on each side of the sheet two bumps arranged symmetrically and close to one another are provided so that the four are close together Hump results in a wart weld. The two humps on each side are expediently placed cross-shaped to one another. The invention requires a lower electrode pressure and a correspondingly lower welding power, with a large-area electrode being used can. The surface of the two outer sheets shows only slight warping at the welding point.
Die Erfindung ist auf der Zeichnung anhand eines Ausführungsbeispieles schematisch dargestellt und nachfolgend beschrieben. -The invention is based on the drawing using an exemplary embodiment shown schematically and described below. -
Fig. 1 zeigt drei mittels Warzenschweißung zu verschweißende Blechlagen im Schnitt undFig. 1 shows three to be welded by means of stud welding Sheet metal layers in section and
Fig. 2 eine Draufsicht auf die mittlere Blechlage.Fig. 2 is a plan view of the middle sheet metal layer.
Mit 1 ist die großflächige Elektrode bezeichnet, welche im Verein mit einer Gegenelektrode die drei Blechlagen 2 mittels Preßdruck zusammenschweißen soll. Zu diesem Zweck erhält die Mittlere Blechlage auf jeder Seite zwei herausgeprägte punktförmige Buckel 3 und 4· Das-Buckelpaar 3 auf der-einen Seite der mittleren Blechlage 2 ist kreuzförmig zum Buckelpaar 4 auf der anderen Seite angeordnet, wobei die Buckel möglichst dicht aneinander gelegt sind. .1 with the large-area electrode is referred to, which, in conjunction with a counter electrode, the three sheet metal layers 2 by means of pressure should weld together. For this purpose, the middle sheet metal layer is given two point-shaped protrusions 3 and 4 on each side The pair of humps 3 is on one side of the middle sheet metal layer 2 arranged in a cross shape to the pair of humps 4 on the other side, the humps being placed as close as possible to one another. .
