Title:
DEVICE AND METHOD FOR CARRYING OUT AND MONITORING A PLASTIC LASER TRANSMISSION WELDING PROCESS
Document Type and Number:
WIPO Patent Application WO/2013/014068
Kind Code:
A3
Abstract:
A device and a method for carrying out and monitoring a plastic laser transmission welding process comprises a processing beam source for emitting a processing beam into a joining zone (1) between two parts being joined (2, 3) while forming a weld (4), a measuring beam source (6) for irradiating a measuring zone (12) with a measuring beam (7), a detection unit (13) for detecting the measuring beam (7) reflected by an interface (5) between the weld (4) and its surroundings in the parts being joined (2, 3), and an evaluation unit (15), connected to the detection unit (13), for determining the depth position of the interface (5) in the parts being joined (2, 3) from the reflected measuring beam (7) that is detected.
