Laser cladding welding is an advanced manufacturing technology that uses a high-energy density laser beam as a heat source to simultaneously melt and rapidly solidify alloy powder or wire with the substrate surface, forming a high-performance cladding layer that is metallurgically bonded to the substrate on the substrate surface. This technology has many unique characteristics, making it widely used in the industrial field.

1、 High precision and low heat input
The laser beam of laser cladding welding has extremely high energy density, which can achieve precise local heating, small heat affected zone, and minimal thermal damage to the substrate material. This enables laser cladding welding to accurately repair and strengthen the surface of parts without changing the properties of the substrate material, thereby improving the service life and reliability of the parts.

2、 Good metallurgical bonding
During the laser cladding welding process, the cladding material and the substrate surface instantly reach high temperatures and melt, forming a good metallurgical bond. This type of bonding has high strength and tight interface bonding, which can effectively improve the wear resistance, corrosion resistance, and fatigue resistance of the cladding layer.

3、 Wide adaptability of materials
Laser cladding welding can use various alloy materials as cladding materials, such as nickel based, cobalt based, iron-based alloy powders or wires. These materials have different performance characteristics, and suitable cladding materials can be selected according to the usage requirements and working conditions of the parts to meet different application needs.


4、 Capable of repairing and manufacturing complex shapes
Laser cladding welding can accurately control the motion trajectory of the laser beam through a numerical control system, achieving surface repair and 3D manufacturing of complex shaped parts. Laser cladding welding can easily handle flat, curved, and irregular structures, providing greater flexibility for the design and manufacturing of parts.

5、 Green and environmentally friendly
In the process of laser cladding welding, the utilization rate of cladding materials is high, and there is almost no waste of materials. At the same time, laser cladding welding produces very few pollutants such as exhaust gas and waste residue, with minimal impact on the environment, which is in line with the green and environmentally friendly development concept of modern manufacturing industry.

In summary, laser cladding welding, as an advanced surface strengthening and repair technology, has many characteristics such as high precision, low heat input, good metallurgical bonding, wide material adaptability, the ability to repair and manufacture complex shapes, and green environmental protection. These characteristics have made laser cladding welding widely used in aerospace, automotive, energy, mechanical manufacturing and other fields, providing strong technical support for improving product quality, reducing costs, and extending service life.
