| Abstract: | In this paper,we introduce the apparatus developed to carry out wide trace cladding with high power CO 2 lasers.To obtain a cladding layer of wide trace,the laser beam was focused to a long and thin rectangle by an integral mirror,and corresponding rectangle powder feeding nozzles with coaxial shielding gas were developed.Cladding layers with smooth surface and uniform thickness were successfully obtained by using this system.The width of cladding layer of a single trace is up to 45mm with the thickness of 3mm when the laser power is 14kW. |
