Laser cladding technology, also known as laser additive manufacturing technology, uses high-energy laser as the heat source and metal alloy powder as the cladding material. Through the synchronous action of laser and alloy powder on the metal surface, it quickly melts to form a molten pool, and rapidly solidifies to form a dense, uniform, and controllable thickness metallurgical bonding layer, thereby significantly improving the wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, and other properties of the workpiece, or achieving the repair of the surface size of the workpiece Strengthen the effect of extending lifespan.
At present, laser cladding has a wide range of applications in industries such as aerospace, shipbuilding, mining machinery, and heavy machinery, mainly used for the maintenance and remanufacturing of key components.
Baochenxin, a subsidiary of Chuangxin Laser, is based on the technological research and development capabilities and production strength of Chuangxin Laser in the laser field. With its long-term industry experience in additive manufacturing and cladding, Baochenxin actively plans to launch specialized lasers and industry solutions for cladding. In the future, laser cladding processing systems will combine with computer numerical control technology to form efficient and automated laser cladding processing equipment, achieving the transformation of laser from traditional "metal hard cutting tools" to "laser digital cutting tools", assisting in the intelligent advancement of cladding application industries, helping enterprises reduce costs, improve efficiency, and promote green, low-carbon, and high-quality development.
The Baochenxin Cladding Series product solution, with high-performance lasers as the core light source and specialized cladding heads and other optical components, has the characteristics of wide application range, strong professionalism, and high repair performance. It has been applied online in multiple leading enterprises in China.
Among them, the specialized laser for laser cladding has advantages such as high electro-optical conversion efficiency, good beam quality, compact volume, and simple maintenance, which play a decisive role in the key performance indicators of laser cladding processing: homogenizing the light spot makes the energy distribution more uniform, and the laser cladding surface is smoother; Integrated structural design, strong anti high reflection ability, and good laser cladding effect; Laser has high stability and strong reliability, which can significantly improve the process quality of various types of cladding scenarios.
Meanwhile, the laser supports 200-1000 μ Customized fiber core diameter with multiple power options (2000W~12000W), users can choose the laser configuration according to different cladding process requirements.
Baochenxin Laser Cladding Industry Laser Solutions can also be equipped with high-performance external optical path couplers for Chuangxin Laser according to demand. This series of optocouplers has advantages such as high coupling efficiency and fast response time, supporting on-site hot swapping of optical fibers, and quickly resuming production.
On the operating system, Baochenxin can also customize the development of laser cladding operating systems according to user needs, starting from the actual business scenarios of customers, and providing one-stop assistance for the intelligent implementation of laser cladding.
The uniformity of laser energy is one of the important factors affecting the uniformity of the cladding layer. Conventional lasers are influenced by the internal fiber structure, and the energy distribution is easily formed into Gaussian or near Gaussian shapes, resulting in high intermediate energy and low edge energy; When the high energy part in the middle reaches the heating threshold, the edge part cannot melt the processed material and can only form a heat affected zone, which cannot achieve uniform cladding effect and affects the appearance quality.
The cladding dedicated laser used in Baochenxin's cladding solution can shape the energy distribution of the output spot to achieve consistent energy intensity at the center and edge. It can simultaneously reach the threshold during processing, with a wide range of single processing and uniform surface quality.
For anti high reflection applications, the cladding series laser adopts a unique hardware level anti high reflection technology with stronger anti high reflection processing ability; The output head adopts Chuangxin high-performance LOE integrated output head, with a dual water-cooled design, which can quickly remove the heat generated by the return light, achieve continuous anti return light treatment, and eliminate factors that may damage the laser, providing protection for customers in processing high reflective materials.
Considering the complex situation of high dust and harsh conditions in the cladding processing site, the laser adopts a fully enclosed structure and modular design, which can continuously operate in harsh environments such as high temperature, high humidity, and high dust, ensuring stable operation of the equipment in harsh environments.
With the continuous development of modern science and technology and industry, the working environment for components is becoming increasingly complex, and the requirements for surface performance are becoming higher, resulting in a significant increase in the scrap rate of parts. Under the condition that the overall performance of the components meets the working conditions, only surface damaged components can be repaired through laser cladding technology. If the scrapped parts caused by incorrect processing or service damage can be repaired, it can not only recover huge economic and time losses, but also improve resource utilization, save precious and rare metal materials, and play a positive role in promoting the sustainable development of the entire social economy, In line with China's sustainable development strategy.
In recent years, the continuous development of laser technology and the continuous increase in the localization rate of upstream core components have promoted the accelerated expansion of laser applications, and the laser cladding industry has also achieved rapid development. From 2016 to 2022, the market size of domestic laser cladding equipment increased from 1.97 billion yuan to 5.02 billion yuan, with a compound annual growth rate of 16.87% during this period.
In the future, as the country's requirements for environmental protection and energy conservation become increasingly high, traditional surface treatment methods will gradually be phased out and restricted. Non polluting, efficient, and high-quality laser cladding will become the preferred choice for the manufacturing industry, effectively promoting the development process of related industries.
