Optical Seam Tracking
Optical seam tracking is a sensor system that detects the joint right before the weld point and calculates path corrections in real time. This prevents thermal distortion of the part.
Physicochemical Mechanism of Action
Optical seam tracking uses cameras or laser scanners to monitor the position and orientation of the joint in real time. These sensors capture movements of the workpiece and correct the welding path accordingly.
Metallurgical Relevance & Welding Risks
Without optical seam tracking, thermal expansion during joining can lead to component distortion, which causes uneven stresses and possible cracks in the weld. Tracking ensures the joint is always correctly aligned, which raises the quality and safety of the weld.
Workshop Practice & Instructions
For optical seam tracking to work effectively, the sensors must be correctly calibrated and set to the specific conditions of the joining process. The cameras or laser scanners should be placed so they capture the entire joint directly ahead of the weld point. For complex parts it is important to use several sensors to ensure detailed monitoring.
