Optical Weld Seam Tracking
Optical weld seam tracking is real-time tracking of the position where the weld is going to be applied. Guided by a QuellTech Q4-60 Laser Scanner, a robot or machine can adjust its path accordingly. During this procedure, it is also possible to adjust several parameters like driving speed, wire feed speed or current, to achieve optimum weld bead formation. Thanks to these adjustments, seam tracking delivers fewer spatters, continuous bonds and uniform heat level. Unlike tactile probes, non-contact optical seam tracking can be programmed to track just the welding seam and skip the tack welds that would throw any tactile-based system off.
Contactless QuellTech Laser Scanners, based on dedicated tracking software, can extract the coordinates to be applied in real time. By means of the selected algorithm, it is possible to track middle and upper or lower corners of the gaps depending on the need. QuellTech is able to design and produce task-specific, tailored laser scanners on demand, covering the entire range from very thin beads to large multi-pass welding.
The client can achieve a better seam quality, a faster path completion, and accurate seam positioning. Furthermore, errors due to thermal warping are minimized.
