Background
Defects such as cracks, air holes and the like in the laser cladding additive manufacturing process are key factors influencing the quality of cladding products. How to perform full-period defect identification in the cladding process is extremely important. The acoustic emission detection is used as an online nondestructive detection mode of a full-period process, so that defects in the cladding process can be detected and identified well, but the temperature of a cladding substrate can be quickly increased due to heat accumulation in the cladding process, and when the temperature of the substrate is higher than the applicable temperature range of the acoustic emission sensor, the acoustic emission sensor can not be normally used.

The prior data in the laser cladding field does not report on a cooling device of a dynamic acoustic emission detection sensor in the laser cladding process. However, in other fields, such as high-temperature pressure vessels, pipelines, etc., the currently used cooling devices are relatively complex in structure, inconvenient to use, and not capable of well radiating heat during use, which can lead to relatively rapid temperature rise of the sensor. Therefore, when the acoustic emission sensor is used for a long time, a new cooling device needs to be designed for the acoustic emission sensor so as to ensure that the acoustic emission sensor works for a long time.
