Emissionsminderung beim Laserauftragschweißen

Wire-based laser metal deposition (LMD-w) releases welding fume particles that are harmful to health and the environment. The potential hazard depends on the chemical composition as well as particle number and size. Using a statistical design of experiments, the emissions are characterized and the depen-dence on relevant process factors is determined. From this, process-intrinsic measures for emission reduction are derived.
