H13 powder is cladded on steel P20 (base) by continuous CO2 laser, and the influence of technological parameters such as the laser power is analyzed. The 3-D model of synchronous powder feeding is built under Gauss heat source. The simulative results in the heat affected zone are compared with the experimental ones, and the average errors of width and depth are 15% and 4. 5%. respectively. It is found that the simulative results provide basic data for investigating of laser cladding further.
