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.

2D/3D Profile Sensors

Sensors of this type measure profiles of objects such as weld seams or glue beads and check roundness or gaps using laser triangulation. Red or blue laser light, open interfaces and various performance classes are available.
