Laser cladding forming of fan-shaped part based on hollow laser beam inside powder feeding technology
Based on hollow laser beam inside powder feeding technology, the study of forming fan-shaped part whose cladding height was unequal was carried out by the method of variable attitude forming and normal lamination method. The connection between cladding height and scanning velocity was analyzed. The cladding with unequal height was formed by the method of piecewise variable velocity combining geometric model and the connection above. Based on this method, the fan-shaped part was formed. The experimental result indicates that the formed part has high-precision dimension and good surface quality. In addition, the microstructures of the part at different parameter have no significant differences, and all achieve small grain size and compact texture.
