With the continuous upgrading of laser welding technology, laser welding technology has undergone a qualitative leap. Now, laser welding machine has been used in many fields, such as high-tech electronics, automobile manufacturing, precision machining and so on. As a direction of laser application, laser welding is the combination of current technology and traditional technology, but it has different advantages from traditional processing.
1.Good laser beam quality
After laser focusing, the power density is high. The focal spot diameter is small after focusing high-power low-order mode laser.
2.Laser welding has the advantages of high speed, large depth and small deformation.
Due to the high power density, small holes are formed in metal materials during laser welding, and the laser energy is transmitted to the deep part of the workpiece through the small holes, with less transverse diffusion. Therefore, the material fusion depth is large in the process of laser beam scanning. High speed and large welding area per unit time.
3.Laser welding is especially suitable for welding precision sensitive parts
Because the laser welding machine has large aspect ratio, small specific energy, small heat affected zone and small welding deformation, it is especially suitable for welding precision and heat sensitive parts, and can eliminate post welding correction and secondary processing.
4.High flexibility of laser welding
Laser welding machine can realize welding at any angle and can weld inaccessible parts; It can weld all kinds of complex welding workpieces and large workpieces with irregular shape. It has great flexibility to realize welding at any angle.
5.Laser welding can weld difficult materials
Laser welding can be used not only for welding between a variety of heterogeneous metal materials, but also for titanium, nickel, zinc, copper, aluminum, chromium, niobium, gold, silver and their alloys, steel, Kovar alloys, etc. Welding between alloy materials.
6.Low labor cost of laser welding machine
Because the heat input during laser welding is very low and the deformation after welding is very small, it can achieve a very beautiful welding effect on the surface. Therefore, there are few subsequent treatments for laser welding, which can greatly reduce or eliminate the huge manual labor in polishing and leveling processes.
7.The laser welding machine is easy to operate
Laser welding machine has the advantages of simple welding equipment, simple operation process, easy to learn and easy to use. The professional requirements for staff are not high, saving labor costs.
8.Laser welding machine has strong safety performance
The high safety welding nozzle can only touch the switch when it contacts the metal, and the touch switch has temperature sensing.
There are safety precautions for the special laser generator during operation. During operation, it is necessary to wear laser generator protective glasses to reduce eye injury.
9.The working environment of laser welding machine is diverse
Laser welding machine can be used in various 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. Its welding quality is slightly inferior to electron beam welding, but 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. For a wide range of work environments.
10.The welding system is highly flexible and easy to realize automation.
It can be seen that the ten advantages of laser welding machine are much better than traditional welding methods. In the future, the application of laser welding technology will not be limited to the current electronic, automotive, instrument and other fields. It will also be more extensive in the military and medical fields, especially in the medical field. It has broad prospects.
