Hollow Laser Beam

A new inside-laser coaxial wire feeding processing is adopted that can ensure a good axiality between wire and laser beam through transmitting wire along the centerline of the laser beam. Basing on the optimization of process parameters and single beads cladding experiments, the causes of the uneven surface of the formed part is analyzed. By putting forward a method of the real-time control of the defocusing amount and the laser power, a fine multi-layer hollow rotary part is formed. The formed part has no subsidence damage and crack on the whole cladding layer. The size of the error is small and the hardness of the laser cladding is uniformly distributed.
