Laser Cladding with Scanning Optics: Effect of Scanning Frequency and Laser Beam Power Density on Cladding Process


BY JOONAS PEKKARINEN, ANTTI SALMINEN AND VELI KUJANPÄÄ Scanning optics is an effective way to manipulate a laser beam for laser cladding. The numerical adjustment of the scanner gives  effect of the scanned beam on the cladding process itself has not been studied very thoroughly so far.

was noticed to be unstable. This limit was cross when scanning frequency was under 40 Hz. Power density’s limit value for stable process was found to be 191 kW/cm2


and higher power densities


than this was found to produce unstable process. If the cladding  and process started to resemble more laser alloying.
