Nowadays, the laser cladding process has a wide range of applications. For other laser processing processes, the diversity, ductility and adaptability of laser cladding process have unparalleled advantages compared with other processes. Laser cladding technology not only establishes the need for specific functions on the surface of raw materials, but also saves a lot of valuable elements, which is quite welcomed by the industry. Nowadays, after decades of development, laser cladding technology has been widely used, especially in industrial applications, such as oil, shipbuilding, aerospace, construction machinery and nuclear power and other industries.
Coal mining field
In the coal mining industry, due to the harsh production environment, the function of coal mining machinery parts needs to be higher. The main effective form of the hydraulic column is the scratch of the coating and the coating off, which will seriously interfere with the function and service life of the product, and overall maintenance is required. The plating is a high-pollution electroplating process, and electroplating is one of the traditional processes to be replaced in our country. The anti-corrosion surface of the column adopts the laser cladding stainless steel layer process. The laser cladding hydraulic support column is a high-end technical product, which effectively improves the anti-corrosion function of the column and improves the service life. Therefore, the use of laser cladding technology to strengthen the hydraulic column has great application potential, and it is also an environmentally friendly and recycling high-tech supported by the state, which can replace the traditional electroplating process.
Power industry
Under certain working conditions, the rotor journal of turbine in power plant will wear out, and the blades of the final stage and the second final stage will often form gas turbidity under high-temperature working conditions for a period of time. Steam turbine is a large equipment and is not easy to transport, so it needs high-reliability laser in situ repair technology.
Aerospace industry
The remanufacturing of aero engine blades has generated a huge industry, with more types of blade materials and high professionalism. After cutting and repairing the blades, a lot of work needs to be done in terms of repairing raw materials, flaw detection technology and life assessment. This can avoid the need to spend huge amounts of money to purchase new parts from abroad in the later maintenance.
Petroleum exploration field
In the petrochemical industry, based on the long-term harsh production environment of equipment, it is easier to cause serious corrosion and severe wear of parts, which will lead to the complete scrap of larger expensive parts, such as drill collars, non-magnetic drill collars, centralizer and jar and other larger parts. Therefore, under the function of reproduction of laser cladding technology, many parts can be restored to their original functions, and the service life of many parts is strengthened.
Laser cladding technology is a high-tech surface modification technology and equipment maintenance technology. It is a set of material preparation and surface configuration as a whole, which is one of the key supporting technologies of green remanufacturing technology.
