In order to solve the problem that temperature field on the surface of molten pool is difficult to measure in laser cladding forming,this paper builds a color CCD coaxial temperature measurement system. The platform can take a clear and stable image of the molten pool through optimizing the experimental parameters,from which we can get the temperature distribution on the surface of the molten pool. To verify whether the temperature distribution obtained is reasonable and accurate,an infrared thermometer temperature measurement system was set up. According to the measurement of different areas’ temperature on the surface,the temperature distribution of molten pool is basically coincident with the CCD measurement results obtained. The consistent temperature distribution from the two different temperature measurement methods shows that the temperature measurement platform is practical and reliable,which lays the foundation of controlling the cladding system by detecting the surface temperature of the molten pool in real time.
