Competitive Strengths
- Cladding layer at high quality
Metallurgical bonding, highly-dense coating with low dilution rate and good resistance to corrosion and abrasion
- Raise cladding efficiency
The cladding robot can work continuously and be immune to worker fatigue or emotional fluctuation
- Accept various powders
Metal, ceramic, composite powder and other metal metal wires available
- Less manual intervention
Due to its high degree of automation, operating risks and costs will be lowered to make cladding safer and more flexible
- Green and eco-friendly
Laser cladding usually results in no pollution nor radiation to environment, in accord with modern industry’s requirements
Mechanical Benefits
- Deft design
* Horizontal rotary table is made of high-strength cast iron and featured by high carrying capacity,
good shock absorption and hard deformation
* It is easy for the infinitely variable spindle to control its speed and support the demands of different cladding crafts; with tapered bore, the spindle can work with standard Morse center to realize both clamping and jacking
* The dust-proof tailstock can be easily moved by a worker and serve for a long time but with low failure rate; the tailstock may go up and down, in order to avoid effect on precision caused by friction between itself and machine tool bed
* We adopt heavy-duty horizontal carrier roller to raise its carrying capacity and supporting range
- Automatic robot-assisted cladding
The robot’s traveling shaft enlarges its operating radius and makes the cladding of large and complex workpieces easier
- Multi-purpose laser cladding head
* Our laser cladding head is compatible with annular, four-way, three-way or paraxial power feeding nozzle to offer various laser cladding crafts
* The special internally supercharged gas path and real-time monitoring lens are also used to prevent smoke dust & spatter and prolong its service life
- Dual-cylinder pneumatic powder feeder
* Driven by servo motor, the disc powder feeder is under SENFENG control system for remote control and stable powder feeding
* In addition, powder can be heated and added continuously (optional)
Control System Benefits
SENFENG intelligent cladding system can take integrated control of the entire cladding process, such as centralized data treatment, fast response and high degree of automation. That will notably enhance cladding efficiency and precision.
- User-friendly operation
The interface is easy to operate. That is, human-machine interaction, laser generator and powder feeding are totally controlled on the CNC system interface.
- Adjust parameters in real time
Laser power and powder feeding speed are adjusted in real time. In other words, you can change cladding parameters at work, with no need for additional shutdown.
- Failure diagnosis
It may detect and output signal feedback in real time. In the event of a failure, automatic alarm will be given in time.

What is laser cladding and how does it work?
Laser cladding is an important method for surface modification of materials. It uses high-energy laser beam to irradiate the metal surface for rapidly melting, expanding and solidifying. The cooling rate typically reaches 102 to 106℃/s, then, a layer of material with special physical, chemical or mechanical properties will take its shape on the substrate surface, thus creating a new composite material. This process can compensate for the lack of high performance in the base material and significantly improve substrate surface properties in terms of wear, corrosion, high temperature and oxidation resistance.
What are technical characteristics of laser cladding?
Compared to commonly used methods such as overlay welding, thermal spraying and plasma spraying, laser cladding has the following advantages:
* The heat-affected zone is small, resulting in minimal deformation of workpiece and a high yield of cladding.
* The layer has fine crystal grains and dense structure, leading to relatively high hardness and better wear and corrosion resistance.
* Due to short duration of laser action, the dilution rate of cladding layer is low, which causes a smaller amount of material melted (typically 5%-8%). Therefore, it is possible to achieve the desired composition and properties even with a thin cladding layer, and to produce new structural features such as metastable phase, ultra-dispersed phase and amorphous phase.
* It is easy to automate the laser cladding, and the quality of cladding layer is always stable.
What materials are typically used for laser cladding?
The materials used for laser cladding are mainly thermal spraying and thermal welding materials, such as self-fusing alloy materials, carbide dispersion, or composite ceramic materials, which possess excellent wear and corrosion resistance. They are usually used in powder form, and during cladding, flames spray-welding may be employed to achieve a smooth surface with good adhesion to the substrate.
What is the warranty period of laser cladding machine?
