Sensor-Guided Path Correction
Sensor-guided seam correction adjusts the welding path in real time to compensate for thermally induced workpiece distortion. This improves weld accuracy and stability.
Physicochemical Mechanism of Action
Sensor-guided path correction uses sensors to measure thermal distortion of the workpiece during welding. This measurement data is transmitted in real time to the robot, which adjusts its movement accordingly.
Metallurgical Relevance & Risks in Welding
Without path correction, thermal distortion can lead to inaccurate weld positions, which can cause cracks or irregularities. Sensor-guided correction minimizes these risks and increases weld quality.
Workshop Practice & Instructions
To implement sensor-guided path correction, the robot must be equipped with appropriate sensors. The sensors must be mounted in the right places to deliver accurate measurement data. The robot programmer must set up and test the correction algorithms to ensure the path is adjusted correctly. Recommended sensors are ultrasonic or laser sensors.
