<p>The invention relates to a protection screen (1) for screening off laser beams, especially laser beams originating from welding installations. The protection screen (1) is characterized in that it comprises light-metal profiled elements (10-13) that are substantially rectangular. It is further characterized in that it comprises chambers configured by inner walls (2) and profiled sections configured on the front and/or laterally. The lateral profiled section is configured step-wise from a front wall (26) towards a back wall (27) so that the light-metal profiled elements (10-14) can be interlinked in series, side wall to side wall towards the protective wall (20, 22; 21, 23; 24, 25), and can be individually detached from one another.</p> |
