摘要： A method and device for laser cladding by independently heating the cladding material and the surface of the workpiece consist in formation of the series of parallel annular laser beams, possibly different wavelengths, with an adjustable distribution of laser radiation power across the annular beams. The annular beams are transformed into a series of conical beams which are separately focused along a single optical axis, along which the cladding material is fed. The device can be supplemented with a cylindrical mirror for the multipass laser radiation through the stream of cladding material with the possibility of the laser radiation return to the laser resonator.
