Automatic Welding Robot Programming with 2D/3D Profile Sensor

Automated welding of metal workpieces with batch size 1 requires micrometer-accurate information on the three-dimensional position and orientation of the objects. To avoid time-consuming programming, a 2D/3D profile sensor with a large measuring range is installed above the welding robot on a linear axis. Using laser triangulation, the sensor measures the workpiece and forwards the recorded data in the form of a point cloud to the analysis module. From this, the dimensions are calculated, which enables the welding program to be determined from a database.
