DETECTION OF SMOKE EVENTS AND ELECTRON BEAM MELTING SYSTEM

摘要

The invention concerns a device (100) to detect a smoke event (SE) in an electron beam melting system (10). To better predict Smoke events or Automatically recognisable, it is proposed that the device be a power meter (150),which is trained to detect a grounding current (IG) and an evaluation unit (160),which has been trained to detect a smoke event (SE) by evaluating the grounding current (IG). The invention also concerns an electron melting plant (10) and a procedure for operating such a plant.
