Jinyan Laser Repairs Shenyang Yuanda Workpiece - Crankshaft

On August 8, Jinyan Laser received two crankshafts, 42CrMoA and 35CrMo, which need to be repaired from Shenyang Yuanda.

The part that needs to be repaired this time is the shaft diameter, the material is 42CrMoA, 35CrMo, and the construction period is 2 days. After long-term use, its size is 0.75mm less than the standard size. The customer requires that the heat-affected zone and thermal deformation are small during the processing process, and the metal properties inside 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 has a 2000W and 3000W all-solid-state laser welding machine; a 4000W high-power fusion laser; a 6000W (CO2) high-power fusion laser; a laser cutter; Sonic 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. Small deformation of parts repaired by laser cladding
   The base material and the cladding material are metallurgically bonded, and the bonding strength is equivalent to that of the base metal
   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, which have 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

In summary, Jinyan Laser adopts advanced laser cladding technology not only to meet the basic requirements of customers, but also to achieve a high degree of customer satisfaction, saving resources and reducing costs.

Each repaired workpiece embodies the technical essence and hard work of the craftsmen. Jinyan Laser can not only save equipment costs, effectively utilize resources, but also coordinate and optimize the economic and social benefits of the enterprise.
