Problems solved by technology

[0003] At present, the measurement of the temperature field in the process of laser remelting is generally to detect several fixed points through thermocouples or manual infrared thermometers, and then analyze and process them. The final experimental results have certain errors, and cannot directly reflect the real-time changes in temperature during the entire remelting process

The equipment has the advantage that great convenience is brought to the acquisition and analysis of the temperature field in the laser re-melting process.

Description

technical field [0001] The invention relates to the technical field of temperature monitoring during laser remelting, in particular to a real-time monitoring device 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...
