With the gradual increase of market demand, laser welding technology is also constantly upgrading, and a qualitative leap has been made from the technical level. At present, laser welding machines have been maturely used in high-tech electronics, automobile manufacturing, precision processing and other fields. As one of the important components of laser applications, laser welding is a combination of current technology and traditional technology, which has some unique advantages compared with traditional welding equipment.
1. Good laser beam quality.
After the laser beam is focused, the beam is dense, the power is high, and the spot is small.
2. Laser welding speed is fast, the depth is large, and the deformation is small.
The laser beam has high power density, and the laser welding forms small holes in the workpiece, and the energy diffuses from the small holes to the depth of the workpiece. Local heating, small heat affected zone, high welding efficiency, large depth, small degree of deformation.
3. Laser welding is suitable for the welding of precision sensitive parts.
When the laser welding machine welds, the aspect ratio is large, the heat affected zone is small, and the welding deformation is small. Robot welding is especially suitable for the welding of precision workpieces and heat-sensitive parts, and the welded product hardly requires secondary processing.
4. High flexibility of laser welding.
Laser welding can realize welding at any angle, can weld parts that are difficult to access, can weld a variety of complex welding workpieces and large workpieces with irregular shapes, can realize welding at any angle, with high flexibility.
5. Laser welding is widely used.
Laser welding is not only suitable for the welding of ordinary carbon steel, stainless steel, aluminum alloy, but also for the welding of titanium, nickel, zinc, chromium, niobium, gold, silver and other metals and their alloys, steel, Kovar alloy 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, laser welding has very little post-processing, which can greatly reduce or eliminate the labor in the polishing, polishing and leveling process.
7. The laser welding machine is simple to operate.
The interface of laser welding equipment is simple and clear, the operation is simple and easy to learn, and the difficulty of starting is low. Low operator proficiency requirements can also save the cost of personnel selection.
8. The laser welder has strong safety performance.
The laser welder only emits light when it touches the metal, which greatly reduces the accident rate caused by misoperation. Wearing laser protective glasses during operation can effectively reduce eye damage.
9. Laser welder is suitable for a wide range of environments.
Laser welders 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 lower than electron beam welding, but the electron beam can only be transmitted in a vacuum, so welding can only be carried out in a vacuum, while laser welding technology can be more advanced. Used in a wide range of working environments.
10. The welding system is highly flexible and easy to automate.
Laser welders also have certain limitations. The cost of laser welding machine equipment is high, and the laser welding machine also requires high installation accuracy of weldments, and the position of the light source on the commodity workpiece cannot have obvious deviations. Although there are some limitations, the future 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 areas, very flexible, easy to automate, laser welding technology is predictable in the future.
