New development of far distance coaxial powder feeding system

Coaxial laser cladding has been widely used to 3D component direct manufacturing and repairing expensive parts. A new far distance coaxial laser cladding system has been developed. It consists of a double hopper powder feeder, a four pass divided powder device, compact coaxial nozzle and controlled temperature CCD camera. Its main technical parameters are as follows: delivering powder mass rate Mp=1—80g/min, delivering powder distance 20m, temperature measuring regions: 700°C - 1500°C.
