Fully automated welding in robot welding cells places great demands on quality and precision because the position of the seam has to be reliably detected by means of sensors before the welding process begins. Only then can the welding material be mechanically applied by downstream components with the required levels of accuracy. 2D/3D profile sensors included in the weCat3D series fulfill requirements for this 3D measuring task for welding seam guidance. The cost-effective complete system consisting of sensor, analysis module and software also offers interfaces from re...
