The evaluation of the current measurement signals is performed by comparison with the stored reference signals using the envelope or threshold method. The Weld Watcher sensors are integrated into the laser with an adapter.

As part of the automatic evaluation of the process signal in the serial production, the result is shown with distinguishing colored marks in one or more welding group images. The graphical visualization shows the operator the test for the welding seam that is notified as being faulty.

Results from the test are shown, as well as the tolerance in which the process must run.
