Numerical Simulation of Feeding Powder Laser Cladding Temperature Field Based on ANSYS

Abstract:

The numerical simulation method of LCRM Using Coaxial Inside-Beam Powder Feeding is put forward in this page. LCRM conduction model is established, the life and death unit to be used to simulate the real laser cladding process. Calculation results show that the molten pool temperature will gradually increase with the number of cladding layers increase; the highest temperature at the point of application of the laser beam position later; in the cladding process, cooling rate is great in high temperature period, and in low temperature section, cooling rate relatively slight.
