Analysis on the layout trend of China's laser cutting industry

laser processing (including laser cutting, welding and surface treatment) is an advanced production technology. China's laser processing industry is making great strides forward. The high-tech term "laser" has changed from "snow in spring" to a real social productivity. "Developing high technology and realizing industrialization" has become the reality of China's laser processing industry

as a new light source, laser has the characteristics of good directivity, high brightness, good monochromaticity and high energy density. The laser industry based on laser has developed rapidly in the world. Now it has been widely used in industrial production, communication, information processing, medical and health care, military, cultural education and scientific research. According to statistics, from high-end optical fibers to common bar code scanners, it is clearly pointed out in the "1015" development plan program for China's petroleum and chemical industry issued by China Petroleum and chemical industry association that the market value of laser related products and services in the adhesive industry is as high as trillions of dollars

the laser industry has formed a complete and mature industrial chain distribution. The upstream mainly includes laser materials and supporting components, the midstream mainly includes various lasers and supporting equipment, and the downstream mainly includes laser application products, consumer products, instruments and equipment. The domestic laser market mainly includes laser processing equipment, optical communication devices and equipment, laser measuring equipment, lasers, laser medical equipment, laser components, etc. the application is in the industrial processing and optical communication market, both of which occupy nearly 70% of the market share

at present, China's laser industry is mainly used in laser processing, medical and other industries, of which the scientific research and development field accounts for 12%, the material processing field accounts for 32%, the communication field accounts for 12%, the information field accounts for 14%, the medical field accounts for 20%, and the measurement and other fields account for 9% and 1% respectively

up to now, there are 5 national laser technology research centers and more than 10 research institutions in China; There are 21 provinces and municipalities that produce and sell laser products, and 20 units that produce and sell finalized products and form a certain scale all year round. These two requirements are contradictory to each other. The domestic laser industry has formed a relatively complete industrial chain consisting of laser crystals, key components, accessories, lasers, laser systems, application development, public service platforms and other links

China's laser processing industry can be divided into four industrial belts: the Pearl River Delta, the Yangtze River Delta, central China and the Bohai rim. The above is a coherent introduction to the functional characteristics of the hydraulic universal testing machine for casting aluminum alloy. The four industrial belts have different focuses. The Pearl River Delta is mainly composed of small and medium-power laser processing machines, the Yangtze River Delta is mainly composed of high-power laser cutting and welding equipment, the Bohai rim is mainly composed of high-power laser cladding and all solid-state laser, and the central China led by Wuhan is covered with large, medium and small laser processing equipment

with the transformation and upgrading of China's manufacturing industry, some old industrial bases and small enterprise bases began to transform to high-end manufacturing. For example, Wenzhou laser industry cluster and Anshan vigorously develop the laser industry

independent innovation

the construction of innovation base is the guarantee for the sustainable development of laser technology industrialization. From the sixth five year plan to the ninth five year plan, the state has listed laser technology as a special project and paid special attention to it. Therefore, today's vigorous development of China's laser industry is possible. At present, the development of laser technology and industrialization in the world is very fast. There are more and more mature technologies in gas lasers and application systems. In the field of solid-state lasers, new crystal materials are emerging, and new laser technologies are also developing. In order to keep up with the development of the world and provide continuous technical support and talent support for China's laser industrialization, we must strengthen the construction of laser technology innovation base, especially the construction of engineering innovation base

maintain the technological development trend synchronized with the international advanced level, focus on breaking through several key technologies, and solve the bottleneck restricting the development of China's laser technology industry. In close connection with the main battlefield of national economic construction, with the transformation and commercialization of scientific and technological achievements as the core, we will focus on solving the core and key technologies of laser unit devices, system integration and processing technology. Strengthen the research and development of new products and provide technical reserves for industrial development

for lasers, optical devices, light guide systems and laser processing equipment supporting components used for laser cutting and welding, we continuously provide new technologies, new designs and new prototypes, and focus on the development and production of high-power axial fast flow CO2 lasers, fully solidified YAG lasers, new mobile laser processing machines and composite laser welding technologies. Specific measures are as follows:

(1) establish an industry common technology research platform for automobile plate cutting and welding; Wide band heat treatment and surface cladding of metallurgical iron and steel rolls, complete sets of equipment for laser welding of steel strips in the metallurgical industry, and equipment for sharpening; Laser processing of underground oil pipe in petroleum industry. Solve the localization of key common technologies and supporting equipment. 1. The fluctuation range of power supply voltage shall not exceed ± 10% of rated value. It shall be serialized, generalized and standardized

(2) establish a new laser research and development platform ① improve the production capacity and product quality of domestic high-power CO2 lasers by introducing foreign axial fast flow CO2 laser technology, and continuously launch high-quality, high-stability and high-power CO2 lasers on the basis of digestion and absorption. Focus on the development of RF excited, axial fast flow and CO2 lasers above 10000 watts. ② Develop high-power, multi wavelength solid-state lasers (1kW), 100-1000w diode pumped solid-state lasers and UV band solid-state lasers. Focus on the development of pump modules and strive to establish a more comprehensive DPSSL production base in China

system integration

based on the "Ninth Five Year Plan" and the "Tenth Five Year Plan" 863 achievements, the "Eleventh Five Year Plan" focuses on three levels: system integration and application, high stability lasers and new lasers, and partially realizes industrialization

(1) the integration of system integration is the core of Wuhan laser processing industry. The system integrator is the leader in the development of a region and an industry. Only when the strength of the system integrator grows, the whole industry can be driven. The purpose of system integrator integration is that each enterprise has its own characteristics and advantages, and there is a certain competitive relationship between them

according to the characteristics of the current system integrators, it is advisable to establish various forms of system integrators, such as solid-state laser equipment, laser cutting complete equipment, laser medical equipment, large-scale laser processing complete equipment and laser processing stations. The existing enterprise owners become the investors of these companies. In the process of integrating the existing system integrators, the government should play a good role of intermediary and service, Create opportunities for enterprises with mature conditions to be listed and financed, further optimize the property right structure, and lay a good foundation for further development

(2) improve the supply chain to create and grow a number of component suppliers with core technologies. The foundation of an industry is supported by many parts suppliers. For Wuhan, such a group of parts suppliers should include optical devices (such as optical lenses, focusing mirrors, reflectors and transmission optical fibers), precision machining, laser power supply and precision electronics and electrics. At the same time, these parts supplier groups should have core technologies in this field, which is of great significance to promote the whole laser processing industry. Supporting enterprises are the foundation of an industry. In particular, supporting enterprises that master core technologies and own independent intellectual property rights play a great role in promoting industrial development

(3) to introduce and digest from a high starting point and encourage the development of a number of supporting enterprises, we should first encourage the cooperation between supporting enterprises and scientific research institutions, which is a relatively quick way; Secondly, enterprises should pay close attention to the trend of technological development and constantly push through the old to bring forth the new; Third, the government can encourage the development of supporting enterprises through the arrangement of science and technology project plans, tax policies and other means

(4) increase market strength, which requires system integrators to invest more in the promotion of laser processing technology and the establishment of market network, including exploring overseas markets at a certain time. Through promotion and application, technical radiation and personnel training, sub centers, processing stations and joint ventures for laser processing demonstration and application will be established in China to promote the development of China's laser processing industry

(5) domestic capital of capital platform: diversify equity investment and introduce listed companies, state-owned investment companies and private capital; Foreign investment: the proportion of foreign investment in the field of energy optoelectronics of Wuhan China Optics Valley is very small. The introduction of foreign capital can start from the supporting industries. After all, foreign capital has technical advantages in most supporting fields related to energy optoelectronics, and the supporting fields of investment are not as large as investment system integration; Foreign enterprises: it is suggested that the national and local governments increase the intensity of financial support for the establishment of regional and industrial laser processing, make full use of the characteristics of domestic economic and social structure, take high efficiency as the goal, apply advanced laser manufacturing technology, and develop, design and manufacture high-efficiency laser processing production lines with international leading level. Introduce foreign advanced technology and funds, and establish several joint ventures to produce lasers and complete sets of equipment, so as to improve the level of China's laser products
