A numerical simulation model of laser cladding based on internal powder feeding through a hollow laser beam is set up by the Ansys Parametric Design Language (APDL). Through analyzing this model, the saddle-shaped distribution of energy absorbed in scanning direction is found and the molten pool temperature field of single laser cladding is observed like a comet[. Base on the single laser cladding experiments, the initial parameters and test plans of laser cladding and the screwy thin-walled part forming are confirmed. The finite element model of laser cladding forming screwy thin-walled part is established. The evolution of temperature field and thermal cycle of the nodes are studied during the screwy thin-walled part forming process. In the emulation laser power is controlled real time according to the analyses above, and the changing value of laser power is obtained to keep the molten pool temperature steady. The screwy thin-walled part is formed successfully based on these data.
