Title (DE) VERFAHREN UND VORRICHTUNG ZUR ÜBERWACHUNG EINER FÜGENAHT BEIM FÜGEN MITTELS LASERSTRAHLUNG
(EN) METHOD AND DEVICE FOR MONITORING A JOINING SEAM DURING JOINING BY MEANS OF A LASER BEAM
(FR) PROCÉDÉ ET DISPOSITIF POUR CONTRÔLER UN JOINT D'ASSEMBLAGE LORS DE L'ASSEMBLAGE AU MOYEN D'UN FAISCEAU LASER
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Überwachen einer Fügenaht, insbesondere beim Fügen mittels Laserstrahlung, bei dem in Bearbeitungsrichtung vor einem Bearbeitungspunkt eine Fügestelle vermessen wird, um deren Position und Geometrie zu erfassen, aus der Position der Fügestelle zumindest eine Position einer Fügenaht ermittelt wird, und in Bearbeitungsrichtung hinter dem Bearbeitungspunkt die Fügenaht vermessen wird, um deren Geometrie an der ermittelten Position zu erfassen. Ferner betrifft die Erfindung eine Vorrichtung zur Durchführung dieses Verfahrens und einen mit einer derartigen Vorrichtung ausgerüsteten Laserbearbeitungskopf.
(EN) The invention relates to a method for monitoring a joining seam, in particular during joining by means of a laser beam, wherein in the processing direction before a processing point a joining site is measured in order to detect the position and geometry thereof, at least one position of a joining seam is determined from the position of the joining point, and in the processing direction after the processing point the joining seam is measured in order to detect the geometry thereof at the determined position. The invention further relates to a device for carrying out said method and to a laser processing head equipped with such a device.
(FR) L'invention concerne un procédé pour contrôler un joint d'assemblage, notamment lors de l'assemblage au moyen d'un faisceau laser, ledit procédé consistant à mesurer un emplacement d'assemblage dans une direction d'usinage en amont d'un point d'usinage, pour détecter sa position et sa géométrie, à déterminer à partir de la position de l'emplacement d'assemblage au moins une position d'un joint d'assemblage, et à mesurer le joint d'assemblage dans la direction d'usinage en aval du point d'usinage, pour détecter sa géométrie à la position déterminée. L'invention concerne en outre un dispositif pour la mise en oeuvre de ce procédé ainsi qu'une tête d'usinage laser équipée d'un tel dispositif.
