In recent years, the growth rate of the fiber laser welding application market has accelerated, with an average annual growth rate exceeding 30%, which has long surpassed the growth rate of laser cutting machines. With the rapid development of laser equipment, laser cutting machines have been widely used in metal processing, but laser welding equipment has not achieved effective attention. However, in recent years, with the rapid increase in the demand for fiber laser welding in several major fields such as optical communication technology, electronics manufacturing, automobiles, batteries, and sheet metal, the market scale of fiber laser welding has continued to expand.
The application of laser in welding starts no later than cutting. At present, the early stage of fiber laser welding in my country is dominated by lamp-pumped laser and fiber laser welding. They are all traditional low-power laser welding, and they are used in several fields such as molds, advertising characters, and jewelry. The scale of application is very limited.
With the continuous improvement of laser power source, more importantly, semiconductor lasers and fiber transmission laser welding equipment have gradually developed fiber laser welding application scenarios, breaking the original technical bottleneck and opening up new market space. Fiber laser has a relatively small spot, which is not suitable for welding. However, manufacturers use the principle of galvanometer swing beam and technologies such as swing welding head to enable fiber laser to effectively realize welding.
Fiber laser welding has gradually entered the domestic high-end manufacturing industries such as aerospace, nuclear power, rail transit, and new energy vehicles. For example, many automobile factories in my country also choose automated fiber laser welding production lines; fiber laser transmission welding machines are mainly used in power batteries. Even more, domestic new energy battery enterprises have used optical fiber transmission fiber laser welding equipment.
Fiber 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. Secondly, it should be the welding of auto parts and body. In China’s auto market, there are many old car companies, new car companies are constantly emerging, with nearly 100 car brands, and the application rate of fiber laser welding in car production is still very low. The second is the application of fiber laser welding in consumer electronics. Among them, the manufacturing of mobile phones and optical communication technology-related processes have a larger space.
It is also worth mentioning that the optical fiber transmission laser welding machine has already entered the heavy-duty stage. The demand for optical fiber laser welding machine dominated by 1000 to 2000 watt fiber lasers has exploded in the past two years, and the price has also fallen sharply. It can easily replace the traditional electric arc. Welding, low-efficiency spot welding and other processes. It is widely used in the welding of stainless steel pipes, aluminum alloys, sanitary ware, hardware factories, metal parts, and railings, doors and windows.
At present, the high-power welding field has also begun to gradually adopt domestic laser sources, and the growth prospects are considerable. In lithium battery manufacturing, automobile manufacturing, rail transit, ship manufacturing and other manufacturing industries, fiber laser welding, as an important link in the manufacturing process, has also ushered in a good opportunity for development. With the continuous improvement of the performance of domestic lasers and the need for large-scale manufacturing to reduce costs, the opportunity for domestic fiber lasers to replace imports has long arrived.
At present, there is a large demand for power from 1000 watts to 2000 watts, and it will dominate in fiber laser welding in the future. Welding of aluminum casings for power batteries, motor batteries, aerospace components, and automobile bodies accounts for a large part. Laser welding is gradually replacing traditional welding processes and becoming the new mainstream of the metal welding market.
