Abstract: A numerical finite element method (FEM) model for studying laser cladding of a pre-placed powder bed under a pulse mode condition was developed, which takes into account the phenomenon of partial re-melting of the clad track, the effect of heat accumulation resulting from successive pulses, and the geometries of the clad coating. The model was used to study the cladding behaviour of an Al-Si alloy on magnesium alloy WE43. Both the theoretical predictions and experimental results showed that it is possible to obtain a clad coating on magnesium alloys, with a relatively low dilution level, under the pulse mode condition. In this respect, the model provides a sound basis for the determination of the process operation window for achieving a low dilution level.
