What are the main advantages of ultra-high-speed laser cladding technology?

30 May,2024

Many people in the industry know that ultra-high speed laser cladding technology is a new type of laser cladding technology developed by the fraunhofer institute of laser technology in germany,Started to promote and apply in China in 2017.


For high-quality laser cladding manufacturers, they provide Ultra-high-speed laser cladding technology alluse semiconductor fiber output lasers or fiber lasers with good beam quality, and use precision-designed high-speed laser cladding heads and high-speed or moving speed motion mechanisms. The coupling of the laser beam, powder beam, and inert gas flow is precisely designed. When working, part of the laser energy is used to heat the powder beam, and the other part of the laser beam penetrates the powder beam to heat the substrate. The powder is melted before entering the molten pool. Or heating to a very high temperature, shortening the time required for powder melting, so a very high cladding line speed can be achieved.


Ultra-high speed laser cladding technology advantage of high efficiency of laser energy utilization


Ultra-high-speed laser cladding technology, due to the precise design of the coupling structure of laser beam, powder beam and inert gas flow, makes most of the laser beam energy act on the powder and workpiece, reducing the reflection and scattering loss of the laser, and greatly improving the laser Energy efficiency.

Ultra-high-speed laser cladding technology can achieve very high cladding efficiency due to its high utilization rate of laser energy, coupled with a very high cladding line speed and a thinner cladding layer (the cladding efficiency can reach0.7m²/the above)。


Ultra-high-speed laser cladding technology also has the characteristics of good coating roughness, good crack resistance and small workpiece deformation.And use this techniqueThe prepared cladding layer is thin, which is very suitable for the preparation of the pre-protective coating on the surface of new parts.
