How does the Weldwatcher® work?
As a result of the interaction between laser and material typically process light is emitted by the work piece itself. This radiation provides valuable information on the process stability and its state. In automated production, by applying clever algorithms and thresholds, process deviations can be sent automatically to the machine's PLC. The system stores all relevant data for traceability reasons in a customer accessible database.
The laser process monitoring system Weldwatcher®
To assure a successful implementation of a process monitoring system into the production chain, automatic communication is mandatory. For traceability reasons all signals and evaluations are assigned to seam numbers and to part numbers. Different sensors for all circumstances from low light conditions to bright processes and from UV to NIR are available. Together with you, we will choose the right sensor(s) in order to meet your detection requirements.
Option WeldWatcher® installed in laser:
In most cases the integration into the laser offers a lot of advantages. For example, with the capability to monitor all optical paths of the laser source, only 1 WeldWatcher® is required. Additionally, many of our customers value the absence of cables and additional sensor housings at the optical head due to better freedom of action.
Option WeldWatcher® installed in process head:
In some cases the handy integration into the laser is not possible due to technical reasons. In these cases we integrate the sensor(s) into the optical welding head directly. Adapters for all common brands are available..
