Apparatus and method for regulating the seam position during laser welding of the blunt edge impacts and their use

摘要

A device for regulating the seam position during laser welding of the blunt edge impacts with a camera (2) and a planar illumination (1), wherein the camera (2) to an image data for a polyquinazolone end unit is connected, characterized in that the camera (2) a molten bath (7) and a butt joint (5) are detected and the regulation as a function of a detected relative displacement of the molten bath (7) of the vertical joint (5) takes place to.
