| Abstract: | To protect the function of metal cladding, especially to reduce the crack rates of metal cladding, the laser-melt-repairing technology is used to repair and strengthen the surface of parts. In actual situations, by applying this technology, some critical parts, for example axes, laser-melt-repairing may strengthen the surface and improve the function of anti-grinding in order to resume the use value. |
