Laser cladding technology has a huge development prospect. In this study, the temperature field of matrix during laser cladding is simulated using the life and death unit method in ANSYS, and the moving rectangle heat source is loaded by APDL language. Through the simulation of the temperature field, the influence of different laser power and scanning speed on the temperature field are obtained. The higher the power, the less the time it takes for the matrix (45 steel) to rise to the same temperature at the same time. The faster the scanning speed is, the slower the substrate heats up at the same time. The end effect problem in laser cladding is preliminarily explored, and the results show that the end effect problem can be solved more effectively by adopting the reserved scheme. Finally, based on the robot control of FL - DLight3-4000 laser is tested. A side-axis powder feeding nozzle is used for powder feeding, the laser power is set to 3 kW, the scanning speed is 0.005 m·s-1, and the powder feeding rate is 25 g·min-1. The temperature at different times at 25 mm from the center of the first cladding layer is measured, and compared with the simulation results in ANSYS, which proves that the test results are basically consistent with the simulation results.
