With the gradual increase in market demand, laser welding technology is continuously upgraded and transformed, and a qualitative leap has
taken place from the technical level. Now, laser welding machines have been maturely applied in many fields, such as high-tech electronics,
automobile manufacturing, precision machining and other fields. As one of the important components of laser application, laser welding is a
combination of current technology and traditional technology. Compared with traditional welding equipment, laser welding machine has some
unique advantages.
1. Good laser beam quality
The beam quality is a measure of the degree of focus of the laser beam. After the laser is focused, the beam density is high and the spot is small.
2. The laser welding speed is fast, the depth is large, and the deformation is small
The power density of the laser beam is high, and a small hole is formed in the workpiece during laser welding, and the energy is diffused from the
small hole to the deeper part of the workpiece. Local heating, small heat-affected zone, high welding efficiency, greater depth, and less deformation.
3. Laser welding is suitable for welding precision and sensitive parts
The laser welding machine has a large aspect ratio, small heat-affected zone, and small welding deformation. Robot welding is especially suitable for
welding precision workpieces and heat-sensitive parts. The welded product hardly needs secondary processing.
4. High flexibility of laser welding
Laser welding can be welded at any angle, can weld inaccessible parts, can weld various complex welding workpieces and large workpieces with
irregular shapes, can be welded at any angle, and has high flexibility.
5. The application of laser welding is wide
Laser welding is not only suitable for welding common carbon steel, stainless steel, aluminum alloy, but also for welding titanium, nickel, zinc,
chromium, niobium, gold, silver and other metals and their alloys, steel, Kovar and other materials. .
6. Low labor cost of laser welding machine
Laser welding has a small heat-affected zone and small welding deformation, which can achieve a very beautiful welding effect. Therefore, the foll
ow-up laser welding needs to be processed very little, which can greatly reduce or eliminate the labor in the grinding, polishing, and leveling
procedures.
7. The laser welding machine is easy to operate
The interface of the laser welding equipment is simple and clear, the operation is simple and easy to learn, and the difficulty of getting
startedis low. The requirement for the proficiency of the operator is low, and the cost can be saved in the selection of personnel.
8. The laser welding machine has strong safety performance The laser welding machine emits light only when it touches metal, which greatly reduces the accident rate caused by human misoperation. It is necessary to wear laser protective glasses during operation, which can effectively reduce the damage to the eyes. 9. The laser welding machine is suitable for a wide range of environments The laser welding machine can be used in a variety of complex working environments, and can be welded at room temperature or under special conditions. For example, laser welding is similar to electron beam welding in many ways. The welding quality is slightly inferior to electron beam welding, but the electron beam can only be transmitted in vacuum, so welding can only be carried out in vacuum, and laser welding technology can be more advanced. Used in a wide range of work environments. 10. The welding system is highly flexible and easy to realize automation. Laser welding machines also have certain limitations. The equipment cost of laser welding machine is relatively high, and the laser welding machine also requires high precision in the installation of weldments, and requires that the position of the light source on the commercial workpiece cannot be significantly deviated. Although there are some limitations, in the future, the application of laser welding technology will not be limited to the current electronic components, automobile manufacturing, instrument manufacturing, sheet metal manufacturing and other fields. There will also be better prospects in new fields, high flexibility, easy automation, and laser welding technology can be expected in the future.
