Optoelectronic sensor measures profile of weld seam or weld bead along line perpendicular to seam. Illuminated by fan of laser light. Image of line digitized and converted to profile of height or depth versus transverse position. Intended to be part of highly automated welding system, used in automatic tracking of seam or automatic profiling of weld bead for immediate evaluation and assurance of quality during welding process. Requires little maintenance other than cleaning glass windows protecting laser and camera.
