Process for trimming a deep drawn sheet metal part
A top (1) piece of sheet steel is welded to a bottom (2) piece of sheet steel by means of a fillet weld. The top piece is welded along its front side and the bottom piece along its surface. A laser beam (3) is guided along a channel so as to create a laser beam fillet weld. Since the top and bottom...

| description | A top (1) piece of sheet steel is welded to a bottom (2) piece of sheet steel by means of a fillet weld. The top piece is welded along its front side and the bottom piece along its surface. A laser beam (3) is guided along a channel so as to create a laser beam fillet weld. Since the top and bottom pieces of sheet steel each have a zinc coating, this coating evaporates and oozes in a specific direction (5). Independent claims are also included for the following: (a) A deep-drawn piece of sheet steel as a piece of motor car bodywork formed from two pieces deep-drawn thin sheet steel linked by a welded joint; (b) and for deep-drawn pieces of sheet steel to be interlinked to a piece of motor car bodywork by a laser welded joint.
Die Erfindung betrifft ein Verfahren zum Besäumen eines tiefgezogenen Blechteils, das längs der Schnittkante mittels einer Laserstrahl-Kehlnaht mit einem zweiten Blechteil verbunden werden soll. Ein solches Verfahren dient zur Vorbereitung der zu verschweißenden Schnittkante. Dabei werden zum Besäumen zwei scherend gegeneinander bewegte Schneidbacken verwendet. Die Schneidkante zumindest einer der Schneidbacken weist Ausbrüche auf, so dass längs der Schnittkante des besäumten Blechbauteils Zähne ausgebildet werden. |
