Shenyang Jinyan Laser Remanufacturing Technology Development Co., Ltd. was established on April 21, 2006 with a registered capital of 10 million yuan. It is located in Shenyang Economic and Technological Development Zone (11 acres of factory area, 3500 square meters of production area), based on the development needs of remanufacturing industrialization , the expansion of scientific research work from the Laser Surface Modification Laboratory of the Institute of Metal Research, Chinese Academy of Sciences to industrial applications.

The following is the recently repaired crankshaft. The part to be repaired this time is the shaft diameter, and the material is 35CrMo. After long-term use, the customer requires that the heat-affected zone and thermal deformation are small during the processing process, and the internal metal properties of the substrate are not changed. The crankshaft is repaired according to the method of laser cladding. Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base layer by adding a cladding material on the surface of the base material, and using a high-energy density laser beam to fuse it with a thin layer on the surface of the base material.

Jinyan Laser owns One 2000W and one 3000W all-solid-state laser welding machine; One 6000W (CO2) high-power fusion laser; A laser cutter; With plasma surfacing machine, supersonic spraying, plasma spraying and large and medium-sized vacuum heat treatment equipment. In response to these requirements, our company has six technical advantages of laser cladding repair:

1. The parts repaired by laser cladding have small deformation;

2. The base material and the cladding material are metallurgically bonded, and the bonding strength is equivalent to that of the base material;

3. The cladding layer can be free of defects such as pores, looseness, inclusions, cracks, etc.;

4. Special materials with specific properties can be designed and configured according to the working conditions of the parts, with strong flexibility;

5. Since the cladding repair can be performed on the key parts of the parts, it can save a lot of precious metal materials and even strategic materials;

6. For extra large parts, on-site cladding repair can be carried out according to the actual situation.
