Abstract:
1. A laser protective wall element for a housing in a laser machining station, comprising: first and second electrically conductive plate-like elements; and an intermediate layer arranged between the first and second electrically conductive plate-like elements separating them from one another, the intermediate layer having electrical hot conductor properties, wherein the first and second electrically conductive plate-like elements are connected to an electrical voltage source and a measuring instrument which detects a measured signal change of at least one of an electrical current, an electrical resistance and an electrical capacity, and wherein a condition of the laser protective wall element is being monitored as a function of the measured signal change; a laser generating unit configured to generate a laser beam; and an electronic evaluation and control unit configured to generate at least one of a deactivation signal for the laser generating unit and a warning signal to take place when the measured signal change exceeds a predetermined threshold value.
