Competitive Strengths
Performance Benefits
The machine is easy to operate and fit for cladding axial, planar and other simply-curved workpieces together with its high-power laser generator, open-style structure, SENFENG intelligent cladding system and pull-push operating table.
- Metallurgical bonding at high strength
The highly-focused laser beam can melt workpiece surface in a flash to form highly-dense metallurgical bonding coating that stands out in strength
- More resistant to abrasion and corrosion
After cladding, there will be a metallurgical layer resistant to corrosion and abrasion on workpiece surface. In this way, the workpiece will serve for a longer time
- Less costs and energy consumption
Save material costs and energy consumption thanks to its small heat input and deformation
- Controllable thickness and hardness
The thickness and hardness of cladding layer are accurately controlled to adapt to different cladding demands
Mechanical Benefits
The modular machine is made of machine tool base, spindle box, upright column, cross beam, protective metal plates, etc.
- Deft design
* The open-style machine facilitates workers to get a whole picture of cladding process
* Its dust-proof design can protect all moving parts from dust, so as to raise running precision and service life of key transmission parts.
* The integrated self-lubrication system is able to lubricate all key moving parts quantificationally at regular period, in order to prolong lifespan.
* Its infinitely variable spindle has high output torque, high rigidity, stable running at low speed and easy speed regulation. The tailstock can move up and down at low failure rate.
- Self-developed laser generator
Unlike others, it has higher electro-optical conversion rate, lower power dissipation and better laser beam.
- 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 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)
- High-strength machine tool bed
The bed base, made of high-strength materials, is indeformable and unbroken at high temperature even after long-time use because of going through 7 standard processes like high annealing and aging treatment
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.
- Record and return from breakpoint
It can record work state in time of unexpected power failure or alarm, then, return to original state after power recover
- Detect water, power and gas signal in real time
Give alarm instantly and take related measures in case of any abnormality like too high water temperature or large current fluctuation
- Failure diagnosis
Analyze all failures during running automatically because of its built-in failure diagnosis modules

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?
