Abstract: Laser materials processing involves a wide range of transport phenomena, power density (up to 10¹²W/cm²) and interaction time (up to picoseconds) for processing objects with sizes ranging from nanometres to metres. The art of modelling this novel process is to develop a proper understanding in selecting the appropriate transport phenomena and boundary conditions for specific applications. This paper summarizes modelling efforts to date, on laser heat treatment, non-equilibrium synthesis, alloying, cladding, welding, cutting, drilling, chemical vapour deposition, and ablation processes. For each process, the transport phenomena, boundary conditions, governing equations, solution techniques and applicability and limitations are reviewed. An extensive bibliography is provided for further reading of the interested scientists and engineers.
