Laser welding heads are widely used in all walks of life

Due to the rapid development of modern science and technology, all walks of life have higher and higher requirements for product welding and processing technology. Traditional welding technology and equipment have long been unable to meet the current situation. The emergence of fiber laser welding heads has just solved this problem, and the market demand is also increasing. Today, WSX Laser summarizes the application of laser welding head welding technology in various industries.

1. Application of laser welding head welding technology in electronic components:

In the traditional soldering process, the soldering surface will generate excessively high temperature and radiation, which will damage the electronic components themselves, cause the electronic components to break or have poor contact, etc., and affect the surrounding environment. Although these adverse effects can be solved by relevant means, they will undoubtedly shorten the service life of electronic components and even affect the subsequent normal work. From the current welding practice in my country, laser welding head welding has been widely used in the field of welding electronic components. Because the laser welding head welding process has the excellent characteristics of being able to heat in a small local area, and also can precisely control the local temperature of the welded parts of the electronic components. Generally speaking, the laser welding head welding process can achieve the ideal state of producing a high average temperature in a small area without adversely affecting the surrounding area.

2. Application of laser welding head welding technology in aluminum alloy welding:

Laser welding head welding technology is also widely used in the welding of aluminum alloy materials in automobile manufacturing. In the welding process of automobile-related parts, side blowing shielding gas is the most commonly used welding method, which can realize all-round protection of automobile galvanized sheet. From the current development practice of China's automobile manufacturing industry, aluminum alloy is a relatively common industrial material, which can prevent body corrosion and reduce vehicle weight. Therefore, aluminum alloy materials are widely used in engines, rims, dashboards, etc. Laser welding head welding technology has unique advantages in the welding of aluminum alloy materials, because it can achieve effective protection of aluminum alloy materials. However, the application of laser welding head welding technology in the practice of aluminum alloy welding also has certain shortcomings, which are also determined by the thermal properties of the aluminum alloy itself. Although this feature can effectively protect aluminum alloy parts, it cannot effectively avoid common phenomena during welding, such as molten pool spatter and pinhole collapse.

3. Application of laser welding head welding technology in magnesium alloy welding:

In recent years, the automobile manufacturing industry has achieved leapfrog development, and the manufacturing materials of automobile parts have gradually changed from aluminum alloys to magnesium alloys. Compared with aluminum alloy auto parts, magnesium alloy has the characteristics of light weight, and its rigidity, strength, electrical conductivity, thermal conductivity and other properties have been improved and optimized to a certain extent. In addition, magnesium alloys can be recycled, with good recycling effect and low economic cost. The laser welding head welding technology can generate oxide film on the welding part during the welding process of magnesium alloy materials, so as to realize the efficient protection of magnesium alloy devices. Not only in the field of automobile manufacturing, but also in the field of aerospace, the widespread use of magnesium alloys has also made laser head welding a mainstream welding technology because it can meet the complex requirements of mechanical equipment production and manufacturing. Used in aerospace, it can effectively reduce the weight of the aircraft.

4. Research progress of laser head welding technology:

Whether from domestic or foreign laser head welding practice, future research on laser head welding technology will focus on the following three aspects: First, effective control of the welding process. Second, the development and upgrading of lasers. Finally, it is the dynamic monitoring of welding defects. Secondly, improving the photoelectric conversion efficiency is the core content of the research and development and upgrading of the laser head, because the structure of the laser in our country is still very complex, how to improve and improve the internal structure and external performance. The laser head is one of the most important tasks at present. In the third aspect, since a single sensing technology cannot meet the requirements of many complex detection tasks, it is necessary to further develop monitors.
