Abstract

Laser cladding has become a useful tool in materials processing for improving the surface properties of the substrate materials, and has been widely used in industry in recent years. In this paper, we study the 3000W CW laser cladding system based on the high power diode lasers. The beam control method is proposed to reduce the collimated beam pointing errors caused during the packaging of the laser stack. At the input current of 84A, the output power and the optical coupling efficiency of this laser cladding system are 3738W and 93.7%, respectively, and at work face the beam spot size is 2.5mm*7.9mm with symmetry intensity distribution. The laser cladding system is also used in cladding the nickel powder onto the iron substrate and the nickel powder can be clothed onto steel plate uniformly.
