Röntgenblick und Lauschangriff sorgen für Qualität

Laserschweissen dank KI in Echtzeit überwachen

(PresseBox) (Dübendorf, )
Mit einem Röntgenversuch an der «European Synchrotron Radiation Facility» (ESRF) im französischen Grenoble wiesen Empa-Forscher nach, wie gut ihre akustische Echtzeitüberwachung von Laserschweissprozessen funktioniert: Mit fast 90-prozentiger Sicherheit erkannten sie die Bildung von unerwünschten Poren, die die Qualität von Schweissnähten beeinträchtigen. Der Nachweis dauert dank einer speziellen Auswertungsmethode, die auf künstlicher Intelligenz (KI) basiert, gerade einmal 70 Millisekunden.

Laserschweissen ist ein Verfahren, das sich zum Fügen von Metallen und Kunststoffen eignet. Es hat sich besonders in der automatisierten Fertigung, etwa in der Automobilindustrie, durchgesetzt, denn ein Laser arbeitet praktisch verschleissfrei, besonders schnell und äusserst präzise.
