Laser processing is to use a high-intensity laser beam, after being focused by an optical system, to process the workpiece through the relative movement of the laser beam and the workpiece to be processed, and to achieve a process of drilling, cutting, welding, cladding, etc. technology. Compared with traditional processing technology, laser processing has the advantages of wide applicable objects, small material deformation, high processing precision, low energy consumption, low pollution, non-contact processing, automatic processing, etc., and has become a new type of manufacturing technology and means.
