How the Weldwatcher® Works

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.

Integration into the Welding Head

Integration into the Laser

In most cases the integration into the laser offers a lot of advantages. With the capability to monitor all optical paths of the laser source, only 1 WeldWatcher® is required. A lot of customers value the absence of cables and additional sensor housings at the optical head for a better liberty of action.

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.
