Welding 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.

2D/3D Profile Sensors

Sensors of this type measure profiles of objects such as weld seams or glue beads and check roundness or gaps using laser triangulation. Red or blue laser light, open interfaces and various performance classes are available.
