| description | The invention discloses a high hardness material laser cladding process method for a roller work surface, wherein a laser cladding technology is adopted to carry out multi-layer cladding of a high hardness alloy powder material on a roller work surface so as to form a high hardness wear-resistance alloy welding layer on the surface. With the present invention, laser cladding process stability, and uniformity and consistency of a welding layer structure and components can be fundamentally ensured, generation of cracks, pores, inclusions and other cladding quality defects can be avoided, a heat affected zone of the matrix can be reduced, a dilution rate can be reduced, and the alloy welding layer with characteristics of firm metallurgy bonding, dense grain refining, high hardness, high wear resistance and high impact load bearing can be finally obtained, wherein the welding layer hardness is more than HRC 55. In addition, after the roller is subjected to rolling use on the machine after laser cladding repair, t |
