Study on effect factors and control process of match between cladding powder and laser beam in coaxial powder feeding laser cladding

摘要

In laser cladding,match between the cladding powder beam and the laser beam is an important factors which directly affects the quality of cladding layer.It was conclused that the match principle between the cladding powder beam and the laser beam is that entire cladding powders are heating in effective diameter of laser beam and fall into effective region of laser beam on the substrate surface and combining with the actual match state of cladding powder beam and laser beam.
