Diagrams 2 Base material

Selecting the appropriate welding cladding powder is the key to ensuring the quality of the cladding layer. The following are several important factors that should be considered when selecting welding cladding powder:

- Base material properties: different base materials (such as steel, cast iron, aluminium alloys, etc.) have different compatibility requirements for cladding powder, need to choose the right powder according to the physical and chemical properties of the base material.

- Working environment: Considering the working temperature of the cladding layer, the type of wear, corrosive media and other factors, choose the type of powder that can meet the needs of a specific working environment.

- Coating process: different coating processes (such as laser coating, plasma spraying, oxyacetylene flame spraying, etc.) on the powder particle size, morphology and mobility have different requirements, should be based on the specific process to select the appropriate powder.

- Cost-effectiveness: Under the premise of meeting the performance requirements, the economy of the powder should be considered comprehensively and the cost-effective material should be selected.

3. Welding cladding powder applications in industry

3.1 Petrochemical field

In the petrochemical field, equipment is often exposed to high temperature, high pressure and corrosive media, nickel-based alloy powder has become the preferred material for petrochemical equipment repair due to its excellent corrosion resistance. Through the cladding process, the durability of the equipment can be greatly improved, extending its service life and reducing downtime and maintenance costs.

3.2 Aerospace

The aerospace industry has very high requirements for lightweight and high strength materials and high temperature resistance. Due to its excellent high temperature performance, cobalt-based alloy powder is commonly used in the repair and surface strengthening of aero-engine parts to ensure reliable operation in extreme environments.

3.3 Mechanical Manufacturing

In the mechanical manufacturing industry, cladding powders are widely used to repair and enhance the performance of mechanical parts. Due to its lower cost and good wear-resistant performance, iron-based alloy powder is commonly used to repair worn parts of agricultural machinery, mining equipment, etc., which greatly improves the use efficiency and life of the equipment.

3.4 Automotive industry

In the automotive industry, engines, transmissions and other key components need to have high wear resistance and corrosion resistance. Surface cladding using ceramic-based powders can significantly improve the performance of parts, extend their service life and reduce maintenance costs. 

4. Future prospects

With the continuous progress of science and technology, the prospects for the application of welding cladding powder in materials science and manufacturing will be broader. In the future, the development of more diversified and functionalised cladding powders will become a trend. Through the combination of innovative materials and advanced fusion cladding technology, the material performance will be further enhanced, providing strong support for the sustainable development of various industries.
