Laser Triangulation Sensor
A laser triangulation sensor projects a laser profile onto the joint and measures the height profile with a camera to provide precise geometry data for adaptive path control.
Physicochemical Mechanism of Action
A laser triangulation sensor works by projecting a laser beam onto a surface. The camera measures the position of the reflected light and calculates the height profile of the joint from it.
Metallurgical Relevance & Welding Risks
Precise measurement of joint size is critical for an optimal weld. Inaccuracies can lead to distortion or cracks. A faulty sensor can provide incorrect data, disrupting seam tracking and compromising weld quality.
Workshop Practice & Actions
Use the laser triangulation sensor to check joint size before welding. Make sure the sensor is properly calibrated and the camera is clearly aimed at the joint. If problems occur, check the light source and calibration.
