Adaptive Laser Sensor

Maximum sensor capacity

The adaptive laser sensor first moves to the programmed start position. The tracking section is then measured online during welding. The laser head which is mounted parallel to the processing point sends a laser beam onto the workpiece surface, receives the reflected beams and transfers the measured results to the robot controller. Here the data is evaluated in order to compensate for material tolerances and heat distortion. Based on the new values the system changes the position of the welding torch and adjusts the process parameter. The online sensor carries out corrections immediately, thus ensuring optimum welding results.

New application possibilities

The operation of the CLOOS laser sensor opens up completely new application areas for automated welding without affecting the cycle times and due to the wide application range offers maximum flexibility. To a large extent the system does not depend on the material – even where workpieces are coated or contaminated – and the scanning width and resolution can be adjusted to the most varied requirements.

Consequent quality

If the tolerance deviations indicated by measurements during welding are too high, the system interrupts the production run. This integrated quality control inhibits faulty welds, thus avoiding extensive rework.
