Inner Hole Laser Cladding Equipment

Inner Hole Laser Cladding Equipment

The inner hole laser cladding equipment has the advantages of high integration, high precision and high adaptability, which can facilitate the efficient and high-quality laser processing of the inner surface of different types of parts.

Advantages Comparison of Inner Hole Cladding

At present, the traditional repair processes for the inner wall of hydraulic cylinder include arc fusion welding and CMT cold fusion welding. The main materials used include copper alloy and a small amount of stainless steel. The surfacing process is characterized by thick cladding layer, simple process and convenient operation. The surfacing process can produce a coating with high quality and close connection with the substrate. Traditional processes such as tungsten inert gas welding or plasma surfacing can produce coatings with a thickness of 2-3 mm, but the thickness of such coatings is too large and waste too much raw materials. Arc surfacing cladding has the disadvantages of large heat affected zone, large penetration, high dilution rate, large heat input, easy to cause changes in the structure, large deformation, large machining allowance, etc. Laser material cladding can produce thinner coatings with a thickness of 0.5-1 mm. Compared with the traditional process, it can significantly reduce the heat input and a single layer of coating can meet the protection requirements for parts. The inner hole laser cladding equipment has the advantages of high integration, high precision and high adaptability. It can facilitate the efficient and high-quality laser processing of the inner surface of different types of parts. It has the accessibility that is difficult to obtain with traditional optical heads. With the existing ultra-high speed laser cladding technology of Sinovel, it can complete the high-speed cladding processing of oil cylinders, columns and other products.

Advantages of laser cladding for inner holes

1. Heat concentration, small heat input, small heat affected zone, and no influence on tissue change;

2. The cladding surface is flat and the machining amount is small;

3. Low melting depth, low dilution of cladding layer and good anti-corrosion effect;

4. Suitable for cladding of various materials, with low cladding cost;

5. The equipment has the advantages of high integration, high precision and high adaptability;

Inner hole laser cladding head

For different working conditions of laser application, the small laser cladding head independently developed by Huirui can be used in relatively narrow working space and pipe inner diameter workpieces. The longest cladding depth of the customized laser cladding head for the inner hole can reach 2m, adapting to the minimum inner diameterΦ40mm, which can solve the technical problems of laser processing on the inner wall of many slender and long diameter parts and laser processing on the restricted position of complex components.

Characteristic

1. Inner hole cladding head is suitable for laser power 2kW, and can be used for pipe diameter and inner diameter≥ φ40mm, length≤300mm. 

2. The total length of the pipe wall section is 358mm, and the total length of the distance between the optical powder center and the positioning end face is 321mm (replaceable). Focus lens can be 0-6mm

Mechanical pitch adjustment within the range.

3. Compared with the copper mirror integral mirror type inner diameter cladding head, this product has lower and stable laser damage. It uses a coaxial annular nozzle to discharge powder

Good focusing effect and higher powder utilization rate.
