Modeling of laser cladding with diode laser robotized system

Surface Engineering and Applied Electrochemistry, 2010
The choice of proper working conditions is a problem for any processing. But for laser processing this procedure is much more serious. The final results of the processing are usually influenced by over 100 factors. So the best way to choose more cheaply and fast the working conditions is to use the processing simulation.
