Abstract

Die Erfindung beschreibt eine Vorrichtung, insbesondere einen Laser-Hybrid-Schweisskopf (1), für einen Laser-Hybrid-Schweissprozess, bei der an zumindest einer Montageplatte (3) Elemente bzw. Baugruppen angeordnet sind, wobei ein Element bzw. eine Baugruppe durch einen Laser (5) bzw. eine optische Fokussiereinheit, einen Schweissbrenner (6) oder einen Crossjet (7) gebildet sein kann. Der Schweissbrenner (6), insbesondere eine in Längsrichtung des Schweissbrenners (6) verlaufende Längsmittelachse (14), ist in einem Winkel (15) zwischen 25° und 45° zu dem Laser (5) bzw. der optischen Fokussiereinheit, insbesondere zu einer im Zentrum einer Laserstrahlung (16) verlaufenden Laserachse (17), angeordnet, wobei die Laserachse (17) einen Winkel zwischen 80° und 100°, bevorzugt 90°, zu der Definitionsebene (10) oder der Oberfläche (11) des Werkstückes (12) aufweist, wobei ein kleinster Abstand des vom Laser (5) bzw. der optischen Fokussiereinheit abgegebenen Laserstrahls (16), und einem aus dem Schweissbrenner (6) austretenden Schweissdraht (13), insbesondere einem Schweissdrahtende (22), zwischen 0 und 4 mm beträgt.
