Development of laser processing technology in China

As the main symbol of the development of science and technology in the 20th century and one of the pillars of optoelectronic technology in the modern information society, the development of laser technology and laser industry is highly valued by the advanced countries in the world.

Laser processing is the largest project in foreign laser applications, and it is also an important means to transform traditional industries, mainly kW to 10kW CO2 laser and 100W to kW YAG laser to realize cutting, welding, drilling, engraving and heat treatment of various materials.

Laser processing technology is a new manufacturing technology. Laser processing technology plays an important role in the transformation of China's traditional manufacturing and processing industry. In the face of such rapid development of laser processing technology and fierce competition in the laser market, China's laser processing technology must strengthen the development of metabolism, which brings more opportunities and challenges to the development of domestic laser enterprises.

The domestic laser industry is developing rapidly at an average speed of 15%. Some domestic laser equipment and light source technology have reached the international advanced level. Last year, China's laser industry began to take shape in large-scale production. As an advanced manufacturing technology, laser processing technology has been used in in various industries, which plays a very important role in the transformation and upgrading of China's manufacturing industry.

Especially with the development of laser, control and material technology, the research of laser re-manufacturing technology is becoming more and more mature. It has been frequently applied to manufacturing industry and become one of the core technologies of re-manufacturing. Laser re-manufacturing technology has been widely used in the maintenance of mechanical engineering, and will also play a role in metallurgy, chemical machinery, power generation and other fields.

After more than 30 years of development, laser technology in China has made thousands of scientific and technological achievements, many of which have been used in productive practice. The output of laser processing equipment is growing at an average rate of 20% every year, which has solved many problems for the technical transformation of traditional industries and the improvement of product quality. For example, laser roughening technology is being popularized in Baosteel, Benxi Steel and other large steel plants, which will change the development trend of automobile panels in China. The quality, function and price of laser marking machine and laser welding machine are in line with the current domestic market demand, and the market share is more than 90%.
