Abstract
A device and a method for performing and monitoring a plastic laser transmission welding process includes a processing beam source for emitting a processing radiation into a joining zone between two joining members so that a weld seam is formed, a measuring beam source for irradiating a measuring zone with a measuring radiation, a detection unit for detecting the measuring radiation reflected by an interface between the weld seam and its surroundings in the joining members, and an evaluation unit connected to the detection unit for determining the depth position of the interface in the joining members from the detected reflected measuring radiation.
