Coaxial laser cladding has been widely used to 3D components direct manufacturing and repairing expensive parts. A new far distance coaxial powder feeding system has been developed. It consists of a mult dipper powder feeder,four path powder divider,compact coaxial nozzle and controlled temperature CCD camera .Its main technical parameters are as follows: powder mass rate of 1-80g/min,delivering distance og powder of 20 meter,temperature measuring rigion of 700-1500 OC and controlled temperature precision of 20 OC.
