Weld Seam Detection on Metal Objects via 2D/3D Profile Sensors

To ensure the quality of all types of welding seams on metallic objects, they must be visually inspected using a standardized procedure. Faults such as cracks, scratches, weld spatters, pores, indentations or edge offsets must be reliably detected. A 2D/3D profile sensor is installed on a robot arm for this purpose. This moves the contour of the welding seam, measures the seam with micrometer accuracy via laser triangulation and generates a 2D height profile. High sampling rates and high resolutions enable short cycle times and high profile quality.
