Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, in particular to an anti-collision laser cladding head. Background Technique

[0002] Laser cladding is a new surface modification technology. It forms a metallurgical bond with the substrate surface by adding a cladding material to the substrate surface and using a high-energy density laser beam to melt and solidify it together with a thin layer of the substrate surface. In the laser cladding process, the laser cladding head can be said to be one of the most important structures. The laser cladding head is mainly composed of optical components, powder feeding components, etc. The light emitted by the laser device and the powder output by the powder feeder form an intersection through the laser cladding head, so that the high-energy laser beam can effectively melt and clad all the powder onto the workpiece surface.

This laser cladding head is a laser cladding head that can stably control the output laser energy. The laser cladding head product can ensure the cleanliness of the internal optical path during installation, commissioning, and maintenance, can record key information of the molten pool, and the multi-spot cladding head can greatly improve the cladding efficiency of existing cladding products and reduce costs.
