Description

Ausbildung der zum Schmelzschweißen ohne Zusatzwerkstoff abgebogenen Ränder von Dünnblechen Die Erfindung betrifft eine Ausbildung der zum Schmelzschweißen ohne Zusatzwerkstoff abgebogenen, mit sich deckenden Kanten aneinanderliegenden Ränder von Dünnblechen.Formation of the bent for fusion welding without filler material Edges of thin sheets The invention relates to a design for fusion welding bent without additional material, with overlapping edges Edges of thin sheet metal.

Nach einem bekannten Verfahren werden die Endflächen der Bleche abgebogen. Die abgebogenen Flächen werden dann so gegeneinandergelegt, daß ihre Kanten sich miteinander decken. Darauf werden die Endflächen der Ränder durch Schmelzen ohne ein zusätzliches Metall verschweißt.According to a known method, the end faces of the sheets are bent. The bent surfaces are then placed against each other so that their edges cover each other. Then the end faces of the edges are melted without an additional metal welded.

Nach dem Verschweißen kann dabei eine an der der Verbindungsstelle der beiden Bleche entgegengesetzten Seite gelegene Kerbe bestehen bleiben. Diese Kerbe kann bei mechanischen Einwirkungen oder thermischen Spannungen Ausgangspunkt von Rissen sein.After welding, one can be attached to the connection point the notch located on the opposite side of the two sheets. These Notch can be the starting point in the event of mechanical influences or thermal stresses be of cracks.

Ziel der Erfindung ist eine Ausbildung der eingangs genannten Art, bei der dieser Nachteil vermieden wird. Hierzu sieht die Erfindung vor, daß eine Hohlkehle in den aneinanderliegenden Rändern im Bereich der Schweißnahtwurzel angeordnet ist.The aim of the invention is an embodiment of the type mentioned above, in which this disadvantage is avoided. For this purpose, the invention provides that a Fillet arranged in the adjacent edges in the area of the weld root is.

Zwar ist bereits eine Ausbildung der Stoßstelle zweier T-förmig zueinander angeordneter Bleche bekannt, bei welcher zur Glättung des Kraftlinienverlaufes an der Stoßstelle Hohlkehlen vorgesehen sind; dabei ist jedoch ein Eindringen des Schweißmaterials in den durch die Hohlkehlen gebildeten Raum nicht vorgesehen.It is true that the joint between two is already T-shaped arranged sheets known, in which to smooth the force lines on the joint is provided with fillets; however, there is penetration of the welding material not provided in the space formed by the fillets.

Die Erfindung wird beispielsweise an Hand der Zeichnung beschrieben, die einen Schnitt der beiden gemäß der Erfindung verbundenen Dünnbleche nach der Schweißung zeigt.The invention is described, for example, with reference to the drawing, a section of the two thin sheets connected according to the invention according to FIG Weld shows.

Gemäß der Erfindung werden in den abgebogenen Flächen 3 und 4 z. B. halbkreisförmige Hohlkehlen 7 und 8 hergestellt. Diese Hohlkehlen verlaufen etwa parallel zu den Rändern und sind nahe den Kanten im gleichen Abstand von diesen angeordnet, so daß sie zusammen einen länglichen Kanal bilden, wenn die Flächen 3 und 4 aneinandergelegt sind.According to the invention, in the bent surfaces 3 and 4 z. B. semicircular fillets 7 and 8 made. These fillets run roughly parallel to the edges and are close to the edges at the same distance from them arranged so that they together form an elongated channel when the surfaces 3 and 4 are placed next to each other.

Wenn die Schweißung an den Rändern dann ausgeführt ist, erstreckt sich die Schweißung 5 ein wenig in den durch die Hohlkehlen 7 und 8 gebildeten Kanal oder Hohlraum hinein. Auf diese Weise wird die unerwünschte Kerbwirkung vermieden. Durch die Ausbildung gemäß der Erfindung können die hergestellten Verbindungen bei einer hohen Temperatur, z. B. in der Nähe von 500° C, verwendet werden. Die gemäß der Erfindung hergestellten Verbindungen vertragen außerdem Unterschiede in der Erwärmung und Ausdehnung zwischen den verbundenen Blechen ohne Schaden.When the weld is done on the edges then it extends the weld 5 is a little in the channel formed by the fillets 7 and 8 or cavity into it. In this way the undesirable notch effect is avoided. By training according to the invention, the compounds produced can be a high temperature, e.g. B. in the vicinity of 500 ° C can be used. According to Compounds prepared according to the invention also tolerate differences in the Heating and expansion between the connected sheets without damage.
