CLOOS Arc Sensor: simultaneous measuring and welding
The CLOOS (Haiger, Germany) arc sensor enables measurement and welding to occur simultaneously with minimal loss in time. The welding torch oscillates along the edges of the weld seam, measuring for differing values on either side. The computer-based robot controller then adjusts the welding head position to place the seam exactly in the center of the joint and corrects the distance of the welding torch to the workpiece if the measured values are not the same on both sides. At the same time, workpiece distortions are corrected for without need for additional parts.
After the robot has welded the root seam, the correction data is saved and used for welding the cover runs, continuously optimizing the build-up of these runs.
The CLOOS arc sensor is compatible with structural Steel and chrome nickel steel and can produce improved results when combined with the CLOOS gas nozzle sensor, which determines the start of the weld seam. It has a max working speed of 200 cm/min and a weld current range of 50-500 A.
