Description
technical field [0001] The invention relates to the technical field of temperature monitoring during laser remelting, in particular to a real-time monitoring method for a laser melting pool. Background technique [0002] In the process of laser remelting, a molten pool is inevitably generated. The evolution of the temperature field determines the heat and mass transfer in the laser molten pool, which directly affects the shape of the molten pool, the structure and performance of the coating and the substrate, and the surface quality of the parts. , so the measurement and detection of the temperature field during laser remelting is crucial. [0003] At present, the measurement of the temperature field in the process of laser remelting is generally done by detecting several fixed points through thermocouples or manual infrared thermometers, and then analyzing and processing. The final experimental results have certain errors, and cannot directly reflect the entire remelting p...
