Blackbird Robotersysteme GmbH offers a new scan solution prototype with integrated distance sensor. The system detects and measures 3-D laser weld seam topographies in high resolution. It has integrated optical coherence tomography (OCT)-based edge tracking and seam topology measurement. In contrast to other sensors or measurement methods, this OCT-based distance measuring offers full flexibility by capturing and analyzing detailed data within and beyond the actual laser processing zone. Examples include analysis of to-be-welded components, seam tracking of fillet welds, and real-time detection of weld errors or imperfections occurring during weld operations.
