Laser cladding equipment is a device that utilizes laser technology for cladding processing and represents an important component of modern manufacturing technology. It works by spraying metal or alloy powder onto the surface of the workpiece and using a laser beam to melt the metal powder, forming a uniform overjet layer. Laser cladding technology offers advantages such as high precision and low energy consumption. Without altering the original properties of the workpiece, it can enhance surface hardness, wear resistance, corrosion resistance, and high-temperature resistance, thereby extending its service life.

What are the requirements of laser cladding equipment for material surface quality?
Laser cladding equipment is a technology that utilizes a laser beam to melt powder material and adhere it to the surface of a workpiece. It is primarily used for repairing and enhancing the performance of metal surfaces. Before performing cladding with laser cladding equipment, a series of requirements must be met regarding the surface quality of the material to ensure the final cladding results meet the desired standards. Below are the surface quality requirements for materials specified by laser cladding equipment manufacturers.
First, the material surface requires a high degree of smoothness. When the laser beam scans the material surface, the surface smoothness directly affects the energy absorption of the laser beam and the melting condition of the material. If the surface roughness of the material is high, it will cause reflection and scattering of the laser beam, resulting in unsatisfactory cladding effects. Therefore, to achieve better cladding results, the material surface should have a high degree of smoothness, and the surface roughness should be controlled within a specified range.
Secondly, the material surface should be free from impurities, oxides, and surface overjet layers. During the laser cladding process, impurities, oxides, and surface overjet layers can affect energy absorption and transfer, leading to unstable cladding and even welding defects. Therefore, before performing laser cladding, the material surface must undergo cleaning treatment to ensure the absence of impurities, oxides, and surface overjet layers.
Third, the material surface should be free of cracks and defects. During the laser cladding process, cracks and defects on the material surface can lead to localized energy concentration, resulting in uneven melting points and thereby affecting the quality of the cladding results. Therefore, prior to performing laser cladding, it is necessary to inspect the material surface to ensure it is free of cracks and defects.
Fourth, the material surface should have good surface roughness control. During the laser cladding process, the surface roughness of the material affects the refraction and scattering of the laser beam, thereby influencing the cladding quality. Generally, different laser cladding equipment and cladding materials have specific surface roughness requirements. Therefore, before performing laser cladding, the material surface must undergo processing to ensure the surface roughness meets the required standards.
Fifth, the material surface should possess flatness. The flatness of the material surface affects the focusing of the laser beam and the morphology during the cladding process. If the material surface is uneven, it will lead to non-uniform focusing points of the laser beam, thereby affecting the quality of the cladding results. Therefore, before performing laser cladding, it is necessary to process the material surface to ensure that the flatness meets the requirements.
In summary, the requirements of laser cladding equipment for material surface quality mainly include smoothness, absence of impurities, oxides and surface overjet layers, no cracks or defects, surface roughness control, and flatness. Only by meeting these requirements can the stability of the laser cladding process and the quality of the cladding results be ensured.
