Fast, precise, reliable: welded seam inspection for industrial applications

Welding permanently bonds components or materials together. That puts high demands on the welded seam quality – 100% inspection is the rule here. Photonfocus develops and produces sensors and ready-to-use embedded vision systems whose high productivity and efficiency make them stand out from the crowd. They are suitable for quality control of everything from laser welds and laser soldering to inert gas welding and other applications.

3D and HDR sensors are used for the welded seam inspection – these create high-resolution images with a very high dynamic range, delivering precise measurement results even in very bright lighting conditions. With their linear-logarithmic sensor curve, Photonfocus sensors can perform 2D and 3D inspections at the same time. In this case, 3D laser triangulation provides information on the profile of the welded seam, while the 2D gray zone analysis analyzes the seam structure, ensuring that even the smallest tears or cavities are detected reliably.

A compact and robust construction, onboard data processing and high transfer rates make the Photonfocus camera systems the perfect solution for use in fully automated inspection systems and standalone solutions.
