Information

High energy laser is used as heat source and alloy powder as cladding material. Through laser irradiation, the alloy powder acts on the surface of the workpiece synchronously, forms a molten pool by rapid melting, and then forms a dense, uniform and controllable thickness metallurgical bonding layer by rapid solidification, which improves the wear resistance, corrosion resistance, high temperature resistance and oxidation resistance of metal parts.

Through high-speed laser cladding equipment technology, coating a layer of special performance coating on the designated area of the workpiece surface can improve the surface performance of the workpiece, make the important parts have the characteristics of super wear resistance and corrosion resistance, and greatly extend the service life of the parts. Laser cladding processing.

After the production of chemical ball valve, the cladding surface has been modified, and the cladding thickness is required to be 1.2 mm, without defects such as pores and cracks, high corrosion resistance requirements, and cladding hardness above 55HRC.

In the petrochemical industry, the equipment is in a bad working environment for a long time, which is easy to cause serious corrosion and wear of parts, and even lead to the complete scrapping of large and expensive parts. High speed laser cladding equipment technology provides the possibility to repair some expensive parts and inconvenient replacement parts. The strength of repaired parts will be twice of the original parts, which saves the cost of new purchased parts for enterprises. Laser cladding processing.

The parts often wrong in chemical equipment include valve, pump, impeller, large rotor journal, wheel disc, shaft sleeve, bearing bush, etc. After the failure of ball valve and shaft parts in chemical industry, cladding repair is needed. The thickness of the coating is 1 mm, and there are no defects such as pores and cracks, so it has a certain corrosion resistance. The hardness of the coating is above 50HRC. Laser cladding processing.

Advantages of laser cladding manufacturers

(1) The heat affected zone on the substrate produced by laser cladding manufacturer is small and the deformation of workpiece is small.

Metallurgical bonding can be realized between cladding layer and matrix material, and the dilution ratio of cladding material is low.

The results show that the cladding layer has fine grain and dense structure, which can obtain high hardness, wear resistance and corrosion resistance.

It can realize selective local fine repair and effectively reduce the repair cost.

Powder material system has strong adaptability, most conventional and special metal powder materials can be coated on the surface of metal parts.
