Laser Cladding by CO2 and Nd:YAG Laser Radiation — •Ernst Wolfgang Kreutz1,2, Gerd Backes1, Ingomar Kelbassa1, Stefanie Keutgen1, Andres Gasser2, and Konrad Wissenbach2 — 1Lehrstuhl für Lasertechnik der Rheinisch-Westfälischen Technischen Hochschule Aachen, Steinbachstrasse 15, 52074 Aachen — 2Fraunhofer-Institut für Lasertechnik, Steinbachstrasse 15, 52074 Aachen
Experimental and theoretical investigations are performed for laser cladding of metallic materials by CO2 and Nd:YAG laser radiation on metalic substrats for different processing variables as laser power, powder feed rate and processing velocity as well as in dependence on substrate properties such as surface properties and geometry. Applications like generating and repair of workpieces are demonstrated including state-of-the-art and future developments.
