| Abstract: | Wide-band lateral powder nozzle plays an important role in broad beam laser cladding. A kind of lateral
powder nozzle in broad beam laser cladding was designed. It introduced the structure of the nozzle and its operating
principle. It could realize the width of feeding powder changeable by rotating shaft lever to adjust the movement of
barrier strip. A feeding powder experiment was conducted on the nozzle. A groove to collect the powder was placed
under the nozzle and computed the effective utilization of powder. It realized the powder using efficiency at about 50
percent. |
