The grain microstructure of molten pool during the solidification of TC4 titanium alloy in the single point laser cladding was investigated based on the CAFE model which is the cellular automaton (CA) coupled with the finite element (FE) method.

The correct temperature field is the prerequisite for simulating the grain microstructure during the solidification of the molten pool.

The model solves the energy equation by the FE method to simulate the temperature distribution in the molten pool of the single point laser cladding.

Based on the temperature field, the solidification microstructure of the molten pool is also simulated with the CAFE method.

The results show that the maximum temperature in the molten pool increases with the laser power and the scanning rate.

The laser power has a larger influence on the temperature distribution of the molten pool than the scanning rate.

During the solidification of the molten pool, the heat at the bottom of the molten pool transfers faster than that at the top of the molten pool.

The grains rapidly grow into the molten pool, and then the columnar crystals are formed.

This study has a very important significance for improving the quality of the structure parts manufactured through the laser cladding forming.
