After decades of development, laser cladding technology has been widely used in aerospace, petroleum, shipbuilding, engineering machinery and nuclear power industries. In 2020, laser cladding will increase significantly in the Chinese market, and downstream industries are paying more and more attention to laser cladding. Today, in the industrial manufacturing field and the upgrading and iteration of new and old technologies, laser cladding technology has process ductility, diversity, The adaptability has incomparable advantages compared with other processes, and the laser cladding technology has great potential.
The key point of laser cladding is that the technical indicators lie in the matching of each technical parameter, including factors such as scanning speed, overlap rate, powder delivery, laser power, substrate and substrate surface hardness, and other factors that comprehensively determine the quality of laser cladding. In-depth research should be done on the process parameters of nickel-based cobalt-based composites and alloy powder cladding to solve a series of factors such as the material application force and the melting point of the cladding layer and the melting point of the material. There are many applications of laser cladding, such as coal mines, nuclear power, glass molds, shipbuilding, and offshore oil exploration industries. At the same time, the laser cladding repair of motor rotors, bearings, bearings in the nuclear power industry, the main shaft and tail shaft of the ship's stern, and some worm surfaces.
What are the advantages of laser cladding over traditional repair methods, and what are the prospects of the laser repair market?
1. The powder and substrate of laser cladding belong to metallurgical bonding, and the bonding strength is relatively good;
2. Laser cladding has a relatively low dilution rate for the substrate and will not cause thermal deformation, which is also the characteristic of laser cladding;
3. The laser cladding equipment is more flexible and can be made into a portable device and brought to the site to cooperate with the robot for partial repair;
For the laser repair market, the laser cladding market has a great prospect. At present, 3000W, 4000W, 6000W and other power ranges can indeed meet the needs of laser cladding at this stage. With the gradual popularization of 10,000 watt lasers, 10,000 watts can be greatly improved. The efficiency of cladding.
