Abstract
Description
Die Erfindung bezieht sich auf eine Schweißverbindung von zwei aufeinanderliegenden Blechen mittels einer Schmelzschweißung, bei der entlang einer Schweißlinie auf die Oberseite des obenliegenden Blechs eine Schweißnaht aufgebracht ist, welche das obenliegende Blech durchdringt und in das untenliegende Blech eindringt.The invention relates to a welded joint of two superimposed sheets by means of fusion welding, in which along a weld line on the top of the overhead sheet, a weld is applied, which penetrates the overhead sheet and penetrates into the underlying sheet.
Bei derartigen Schweißverbindungen sind zu Beginn des Schweißvorgangs zunächst beide Bleche noch kalt. Durch den beginnenden Schweißvorgang wird zunächst das oben liegende Blech erwärmt und lokal geschmolzen, während die Wärme erst mit einem zeitlichen Versatz das unten liegende Blech erreicht und lokal anschmilzt. Dadurch ist am Anfang der Schweißnaht nur das obenliegende Blech, nicht aber das untenliegende Blech geschmolzen, so dass die Verbindung der beiden Bleche am Anfang der Schweißnaht nicht oder nicht ausreichend fest vorhanden ist.In such welded joints initially both sheets are still cold at the beginning of the welding process. As a result of the incipient welding process, the sheet lying above is first heated and locally melted, while the heat first reaches the underlying sheet metal with a time delay and melts locally. As a result, at the beginning of the weld only the upper sheet, but not the underlying sheet melted, so that the connection of the two sheets at the beginning of the weld is not or not sufficiently fixed.
Aufgabe der Erfindung ist es daher einer Schweißverbindung sowie ein Verfahren zum Erzeugen einer Schweißverbindung zu schaffen, bei der die die Bleche durchdringende Schweißnaht von ihrem Anfang an eine hohe Festigkeit aufweist.The object of the invention is therefore to provide a welded joint and a method for producing a welded joint, in which the weld penetrating the sheets has a high strength from its beginning.
Diese Aufgabe wird für eine Schweißverbindung dadurch gelöst, dass das obenliegende Blech im Anfangsbereich der Schweißlinie vor Beginn des Schweißvorgangs eine durchgehende Ausnehmung aufweist und die Schweißnaht im Bereich der Ausnehmung beginnt.This object is achieved for a welded joint in that the overhead metal sheet in the initial region of the weld line before the beginning of the welding process has a continuous recess and the weld begins in the region of the recess.
Bei dieser Ausbildung beginnt der Schweißvorgangs im Bereich der Ausnehmung, so dass zunächst das untenliegende Blech erhitzt und angeschmolzen wird. Wenn dann der Schweißvorgang am Ende der Ausnehmung auch das obenliegende Blech erreicht und dieses erhitzt sowie schmilzt, ist das untenliegende Blech bereits heiß und an der Oberfläche flüssig, so dass sich das im obenliegenden Blech geschmolzene Material sofort mit der Schmelze des untenliegenden Blechs verbinden kann.In this embodiment, the welding process begins in the region of the recess, so that first the underlying sheet metal is heated and fused. Then, when the welding process at the end of the recess also reaches the top sheet and this heats and melts, the underlying sheet is already hot and liquid on the surface, so that the material melted in the top sheet can immediately connect to the melt of the underlying sheet.
Damit wird eine Schweißnaht mit einer hohen Festigkeit erreicht.This achieves a weld with a high strength.
Um eine ausreichende Bewegungsstrecke zum Erhitzen des untenliegenden Blechs zu erhalten, kann die Ausnehmung ein sich in Längserstreckungsrichtung der Schweißlinie erstreckendes Langloch sein.In order to obtain a sufficient movement distance for heating the underlying metal sheet, the recess may be a slot extending in the longitudinal direction of the welding line.
Grundsätzlich kann die Schmelzschweißung jede Art von Schmelzschweißung sein.Basically, fusion welding can be any type of fusion welding.
Vorzugsweise ist die Schmelzschweißung eine Lichtbogenschmelzschweißung oder eine Laserschmelzschweißung.Preferably, the fusion welding is an arc fusion welding or a laser fusion welding.
Die Aufgabe wird weiterhin durch ein Verfahren zum Erzeugen einer Schweißverbindung von zwei aufeinanderliegenden Blechen mittels einer Schmelzschweißung gelöst, bei der entlang einer Schweißlinie auf die Oberseite des obenliegenden Blechs eine Schweißnaht aufgebracht ist, welche das obenliegende Blech durchdringt und in das untenliegende Blech eindringt, wobei das obenliegende Blech im Anfangsbereich der Schweißlinie mit einer durchgehenden Ausnehmung versehen wird und nach Auflegen des obenliegenden Blechs auf das untenliegende Blech die Schweißnaht beginnend im Bereich der Ausnehmung aufgebracht wird.The object is further achieved by a method for producing a welded joint of two superimposed sheets by means of fusion welding, in which along a weld line on the top of the overhead sheet, a weld is applied, which penetrates the overhead sheet and penetrates into the underlying sheet, the overhead sheet is provided in the initial region of the weld line with a continuous recess and the weld is applied beginning in the region of the recess after placing the overhead sheet on the underlying sheet metal.
Vorzugsweise erfolgt dabei zunächst nur ein Schmelzen des untenliegenden Blechs im Bereich der Ausnehmung und ab dem dem weiteren Verlauf der Schweißlinie zugewandten Rand der Ausnehmung sowohl ein durchdringendes Schmelzen des obenliegenden Blechs als auch ein eindringendes Schmelzen des untenliegenden Blechs.Preferably, only a melting of the underlying sheet metal in the region of the recess and, starting from the edge of the recess facing the further course of the weld line, both a penetrating melting of the overhead sheet and a penetrating melting of the underlying sheet occur.
Dieses Verfahren führt zu den gleichen Vorteilen wie oben genannt.This method gives the same advantages as mentioned above.
