Laser Triangulation Sensor
A laser triangulation sensor projects a laser profile onto the weld joint and captures the geometry with a camera. This enables precise seam tracking and quality control.
Physical-Chemical Working Principle
A laser triangulation sensor sends a laser beam onto the weld joint, which is then reflected by a mirror or special surface. A camera captures the returning laser beam and calculates the distance based on the angle of the beam. This enables precise real-time measurement of the weld joint.
Metallurgical Relevance & Welding Risks
Accurate measurement of the weld joint is critical for the quality and safety of the connection. A faulty sensor can produce inaccurate data, leading to errors in seam tracking and potential defects in the weld result. This can pose risks such as cracks or failures.
Workshop Practice & Action Instructions
Use the sensor to continuously monitor the weld joint and accurately control the seam position. Ensure the laser beam is clearly directed at the joint without interference like shadows or reflections. Calibrate the sensor regularly to ensure measurement data is correct.
