Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing, in particular to a cooling structure of a laser cladding device. Background Art

[0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base material by adding cladding material to the surface of the base material and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the base material. After laser cladding, the surface temperature of the material is very high and it needs to be cooled.

[0003] Although the current laser cladding device can meet the processing needs, it does not have the function of cooling the material and requires additional cooling equipment, which leads to increased costs. Based on this, we propose an improved cooling structure of the laser cladding device. Utility Model Content
