In the past few years, laser technology has developed rapidly, and laser cutting machines have been widely used in metal processing, but laser welding machines have not been well valued. One of the reasons is that the market size of laser welding machines is small, and it is difficult for some companies engaged in laser welding to expand. However, in recent years, with the rapid increase in the demand for laser welding in several major fields such as automobiles, batteries, optical communication, electronic manufacturing, and sheet metal, the market size of laser welding has gradually expanded.

The application of laser in welding does not need to be cut late. There are also enterprises specializing in laser welding in my country. In the early days, lamp-pumped laser and YAG laser welding were the main ones, which were all very traditional low-power laser welding. , jewelry and other fields have been applied, the scale is very limited.
In recent years, with the continuous improvement of laser power, more importantly, semiconductor lasers and fiber lasers have gradually developed laser welding application scenarios, breaking the original technical bottleneck of laser welding and opening up new market space.
The light spot of the fiber laser is relatively small, which is not suitable for welding, but the manufacturer uses the principle of galvanometer swing beam and the technology of swing welding head, so that the fiber laser can realize welding well.
Laser welding has gradually entered domestic high-end industries such as automobiles, rail transit, aerospace, nuclear power, new energy vehicles, and optical communications. For example, my country’s FAW, Chery, GAC Honda, etc. have all adopted automated laser welding production lines; CRRC Tangshan locomotive , CRRC Qingdao Sifang locomotive also adopts kilowatt-level welding technology; in terms of power batteries, there are more leading companies such as Ningde Times, AVIC Lithium, BYD, Guoxuan, etc. have used a large number of laser welding equipment.
Laser welding of power batteries should be a relatively bright welding application demand in recent years, which has greatly promoted many new energy battery companies. The second should be the welding of automobile bodies and parts. In China’s automobile market, there are many old car companies, and new car companies are emerging. There are nearly 100 car brands, and the application rate of laser welding in automobile production is still very low, and there is still room for the future. very large. The third is the laser welding application of consumer electronics, in which the process space related to mobile phone manufacturing and optical communication is relatively large.
The field of high-power welding has also begun to use domestic light sources gradually, and the growth prospects are considerable. As an important link in the manufacturing process, laser welding has also ushered in a good opportunity for development in industries such as lithium battery manufacturing, automobile manufacturing, rail transit, and ship manufacturing. With the continuous improvement of the performance of domestic lasers and the need to reduce costs in large-scale manufacturing, the opportunity for domestic fiber lasers to replace imports has come.
According to general welding applications, the current demand for power from 1000 watts to 2000 watts is large and will dominate in laser welding in the future. Many hand-held laser welding is used for welding metal parts and stainless steel parts with a thickness of less than 1.5mm, and 1000 watts of power is enough. In the welding of power battery aluminum casing, motor cells, aerospace components, automobile bodies, etc., 2000 watts can meet most needs. Laser welding will gradually replace the traditional welding process in the future and become the mainstream process in the metal welding market.
