Colour sensors for the presence check of welding wires

When welding components, the weld seam is automatically inspected for quality assurance purposes. The inspection is performed using CFO100 colour sensors which detect the weld seam while the component is being rotated. As the weld seam has a different colour than the surrounding materials, the presence of the seam can be reliably inspected. The multi-teach function enables teach-in of all colour shades of the weld seam to ensure a reliable distinction. If there is no weld seam, a switching signal is output.
