LASER CLADDING METHOD

摘要

In the present invention, a laser cladding method is provided which belongs to the art of laser processing. The laser cladding method is characterized in that using laser beam emitted from a semiconductor laser to melt alloy powder for laser cladding on the surface of a hydraulic support column, so that a laser cladding layer is formed; the semiconductor laser is a laser functioning with semiconductor material as gain medium and lighting by means of semiconductor material transition among energy bands; the hydraulic support column is mainly made of alloy steel of 27SiMn. With the laser cladding method, the energy absorption efficiency of laser beam can be increased, and the energy utilization efficiency is increased, so that the power consumption is saved.
