Metal sheets connecting method for e.g. door, of motor vehicle, involves bending end section of outer metal-sheet, placing inner metal sheet on bent end section of outer sheet, and positively connecting end sections with one another

The method involves bending an end section (14) of an outer metal sheet (10). An inner metal sheet (12) with an end section (16) is placed on an outer surface (30) of the bent end section of the outer metal sheet. The end sections of the inner and outer metal sheets are connected with one another in...

Beschreibung
Zusammenfassung:	The method involves bending an end section (14) of an outer metal sheet (10). An inner metal sheet (12) with an end section (16) is placed on an outer surface (30) of the bent end section of the outer metal sheet. The end sections of the inner and outer metal sheets are connected with one another in a positive fit manner by a laser soldering or welding. The end section of the outer metal sheet is folded, and a rod-or-disc shaped auxiliary tool is used during folding of the end section of the outer metal sheet. Um bei der Herstellung einer Tür oder Klappe für ein Kraftfahrzeug das Innenblech an dem Außenblech zu befestigen, wird das Außenblech (10) mit einem Endabschnitt (14) umgebogen, insbesondere gefalzt, und auf den umgebogenen Endabschnitt (14) wird der Endabschnitt (16) des Innenblechs (12) aufgelegt. Anschließend werden die beiden Endabschnitte (14, 16) stoffschlüssig miteinander verbunden, z.B. durch Laserlöten.
