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.

MLWL 2D/3D Profile Sensors

2D/3D profile sensors from the weCat3D series use the principle of laser triangulation to create 2D height profiles and 3D point clouds. The MLWL model offers unbeatable profile quality thanks to its optimized, high-quality optics.
