Title (DE) VORRICHTUNG ZUM MANUELLEN LASERSCHWEISSEN
(EN) DEVICE FOR MANUAL LASER WELDING
(FR) DISPOSITIF POUR SOUDAGE LASER MANUEL
Abstract:
(DE) Bei der Vorrichtung zum Laserschweißen von Werkstücken ist mindestens ein von einer Laserstrahlungsquelle emittierter Laserstrahl durch ein manuell von einem Bediener bewegbares Laserbearbeitungsgerät in den Fügebereich von Werkstücken gerichtet. Am und/oder im Gehäuse ist mindestens ein Sensorelement, das zur Erfassung der Position des Brennflecks auf der Werkstückoberfläche ausgebildet ist, vorhanden. Die mit dem/den Sensorelement(en) erfassten Positionssignale werden einer Regeleinrichtung zugeführt, wobei die Regeleinrichtung so ausgebildet ist, dass eine Auslenkung der Position des Brennflecks des mindestens einen Laserstrahls auf eine vorgegebene Position im Fügebereich der Werkstücke entlang eines vorgegebenen Schweißnahtverlaufs erreichbar. Allein oder zusätzlich ist im oder am Laserbearbeitungsgerät eine Einrichtung, die zur Auslenkung des Laserstrahls in mindestens eine Achsrichtung ausgebildet, wobei die mindestens eine Achsrichtung in einem Winkel von mindestens 10 ° in Bezug zur Richtung des Schweißnahtverlaufs an der jeweiligen Position des Brennflecks ausgerichtet ist.
(EN) The invention relates to a device for the laser welding of workpieces, wherein at least one laser beam emitted by a laser radiation source is directed into the joining region of the workpieces by means of a laser processing apparatus that can be manually moved by an operator. At least one sensor element designed to sense the position of the focal spot on the workpiece surface is present on and/or in the housing. The position signals captured by means of the one or more sensor elements are fed to a control apparatus. The control apparatus is designed in such a way that a deflection of the position of the focal spot of the at least one laser beam onto a specified position in the joining region of the workpieces along a specified weld seam course can be achieved. Alone or additionally, an apparatus designed to deflect the laser beam into at least one axial direction is provided in or on the laser processing apparatus. The at least one axial direction is oriented at an angle of at least 10° to the direction of the weld seam course at the particular position of the focal spot.
(FR) L'invention concerne un dispositif pour le soudage laser de pièces dans lequel au moins un rayon laser émis par une source de rayonnement laser est orienté dans la zone d'assemblage de pièces par un appareil d'usinage laser pouvant être déplacé manuellement par un utilisateur. Au moins un élément capteur, qui est conçu pour détecter la position de la tache focale sur la surface de la pièce, est disposé sur et/ou dans le boîtier. Les signaux de position détectés par le ou les éléments capteur sont introduits dans un dispositif de régulation, le dispositif de régulation étant conçu de manière telle qu'une déviation de la position de la tache focale dudit au moins un rayon laser sur une position prédéfinie dans la zone d'assemblage de la pièce le long d'une allure prédéfinie du joint de soudure peut être atteinte. Un dispositif, qui est conçu pour la déviation du rayon laser dans au moins une direction d'axe, est disposé seul ou en plus dans ou sur l'appareil d'usinage laser, ladite au moins une direction d'axe étant orientée avec un angle d'au moins 10° par rapport à la direction de l'allure du joint de soudure au niveau de la position respective de la tache focale.
