Technical Field

[0001] The utility model relates to the technical field of thermal spraying, in particular to a thermal spraying gun with temperature monitoring function. Background Art

[0002] Thermal spraying refers to heating and melting the coating material, atomizing it into extremely fine particles with high-speed airflow, and spraying it onto the surface of the workpiece at a very high speed to form a coating. According to the needs, different coating materials can be selected to obtain one or more properties such as wear resistance, corrosion resistance, oxidation resistance, and heat resistance. During thermal spraying, the temperature of the workpiece is a very important process parameter. At present, independent temperature monitoring instruments are generally used during spraying processing. After pausing, the temperature is measured manually, which affects the production rhythm and reduces the production efficiency. Utility Model Content
