Laser rust removal machine, in simple terms, is a kind of equipment that uses a high-energy laser beam to interact with the surface of an object to remove surface contaminants, coatings, rust and other impurities. It breaks the limitations of traditional cleaning methods and has brought huge changes to the cleaning industry with a brand new, efficient and environmentally friendly concept. Today, let us first study the mechanism of the interaction between laser light and matter.

In the wave of transformation and upgrading of modern manufacturing, laser technology, as one of the core supporting technologies, is driving the transformation of the global processing industry. The core competitiveness of laser processing technology stems from the continuous iteration of lasers.

Today, we continue the discussion on the industrial chain and market size of China's laser processing equipment manufacturing industry in the previous issue, and take a look at the current status of the industry development. Current status of the development of the laser processing equipment manufacturing industry: In recent years, influenced by factors such as macroeconomic development, manufacturing industry upgrading, and national policy support, my country has become the world's largest industrial laser market to date. At the same time, with the proposal of "Made in China 2025", the continued growth of China's economy and the development of China's manufacturing industry have a strong driving effect on the market demand of the laser processing equipment industry, and have created favorable conditions for technological innovation in the laser processing equipment industry. In recent years, the localization rate of the industry has increased, the downstream fields of the industry have developed rapidly, especially the significant growth in sheet metal cutting demand, and the vigorous development of the microelectronics manufacturing industry have driven the rapid growth of the market size of my country's laser processing equipment industry. Data shows that the market size of China's laser processing equipment industry in 2024 will be about 89.9 billion yuan. From the perspective of market structure, laser cutting equipment is the largest sub-segment of laser processing equipment in my country, with a market share of about 39.27%, followed by laser welding equipment and laser engraving equipment, with market shares of 15.93% and 11.77% respectively.

Overview of laser processing equipment manufacturing industry: Laser processing is an industrial application of laser technology. It focuses a certain power of laser on the object to be processed, so that the laser interacts with the object, heats, melts or vaporizes the processed material to achieve the processing purpose. Laser processing is a typical non-contact processing. Compared with other processing methods, it has significant advantages such as fewer subsequent processes, good controllability, easy integration, high processing efficiency, low material loss, low environmental pollution, high flexibility and high quality. Laser processing equipment is a high-tech product that integrates a variety of high-tech technologies. It exists in almost all industrial sectors and reflects a country's production and processing capabilities, equipment level and competitiveness. Therefore, the laser processing equipment manufacturing industry is one of the industries that various countries pay the most attention to and develop the fastest. According to the nature of the laser, laser processing equipment can be divided into gas lasers, solid lasers, semiconductor lasers, liquid lasers, chemical lasers, free electron lasers, etc.; according to different functions, it can be divided into laser welding machines, laser engraving machines, laser cutting machines, laser marking machines, etc. Laser processing equipment manufacturing industry policy: In recent years, China's laser processing equipment manufacturing industry has received high attention from governments at all levels and key support from national industrial policies. The country has successively introduced a number of policies to encourage the development and innovation of the laser processing equipment industry. For example, in June 2023, the Ministry of Industry and Information Technology and other five departments issued the "Implementation Opinions on Improving the Reliability of the Manufacturing Industry", proposing to focus on improving the reliability of industrial mother machines such as vertical/horizontal machining centers, five-axis linkage machining centers, turning and milling composite machining centers, heavy CNC machine tools, large die-casting machines, hydraulic/servo presses, laser welding and cutting equipment, vacuum heat treatment furnaces, additive manufacturing, large high-end intelligent agricultural machinery, small and suitable agricultural machinery in hilly and mountainous areas, and other agricultural machinery equipment, industrial robots and other products. In January 2024, the Ministry of Industry and Information Technology and other seven departments issued the "Implementation Opinions on Promoting the Innovation and Development of Future Industries", proposing to develop intelligent manufacturing, biomanufacturing, nanomanufacturing, laser manufacturing, and circular manufacturing, break through key core technologies such as intelligent control, intelligent sensing, and simulation, promote flexible manufacturing, shared manufacturing and other models, and promote the development of industrial Internet and industrial metaverse.

Although there are no so-called technical secrets in the welding process, there are many welding techniques, methods and processes in the actual welding process that can make the welding process easier. These processes are called technical know-how. Welding technical know-how can save time, cost and labor, and can even determine the success or failure, profit or loss of welding. Most welding processes are mainly based on scientific research, and some welding processes are based on actual welding experience. This article introduces the synthesis of welding experience in practice.

In the 1970s, laser marking machine had already emerged, and after long-term development and practice, it has gradually become widely known and become a common office tool in daily office. The global fiber laser marking machine market size has shown an overall downward trend in recent years, from US$37.06 billion in 2016 to US$33.98 billion in 2021.

Laser equipment is currently widely used in many processing fields such as material cutting, welding, surface treatment, drilling, and marking. It not only improves production efficiency and reduces production costs, but also improves product quality, becoming one of the key technologies to promote the transformation of industrial manufacturing to high-end and intelligent.

Currently, among my country's laser equipment, cutting accounts for 41% in terms of revenue, and its application is the most mature. However, in 2021, the sales volume of my country's laser cutting equipment was about 12% of the output of metal cutting machine tools, and the penetration rate was still low. Next is welding and marking, which accounted for 13%. The penetration rate of laser welding is lower, and there is more room for growth.
