Can Laser Welding Machine Welding Aluminum Products?
Laser welding refers to the use of laser beams that use high -speed motion on the surface of the material to be welded, so that the laser and the welding material have a strong interaction, thereby generating instant physical chemistry processes such as melt and gasification. Laser welding is widely used in the automotive industry, light industry, construction and other fields.
Compared with traditional methods, laser welding has many outstanding advantages:
●Small deformation of workpieces
When laser welding, the workpiece does not need to be affected by external forces, and it only needs to be deformed by the flexibility of the welding material itself. Due to the concentration of laser radiation energy, it can be melted into the weld in a short period of time to obtain a small welding deformation.
The advantages of high laser welding speed, large -weld and width ratio, good welding quality, high degree of automation, and low production costs are particularly suitable for welding between thin plate heterogeneous materials.
Due to the high laser power density and concentration of energy, the thermal impact on the workpiece is very small, and there is no obvious melting, oxidation and carbonization in the thermal impact area. Therefore, there is no obvious stress and deformation after welding.
●High welding efficiency, low cost
1. High welding efficiency, aluminum alloy with welding thickness of 2.5 mm;
2. Laser welding deformation is small, which can be reduced by 30%-40%compared with ordinary arc welding;
3. High laser processing accuracy, good processing quality, and high production efficiency;
4. Laser has a strong direction and will not be affected by the direction of light;
5. Material connection and multi -material connection can be achieved. Because the laser has good directionability, unilateral or bilateral heating can be achieved, so welding complex shapes can be performed.
●You can process the heterogeneous material
During laser welding, the surface and internal heating time of the welding material is not long. The workpiece only changes during the cooling process, and there will be no thermal stress. Therefore, laser welding can be welded with heterogeneous materials. Such as aluminum, copper, steel and titanium alloy and welding of some difficult welding materials, laser welding can achieve good results.
●No smoke during welding
Laser welding does not need to be preheated on the welding. During the welding process, there is no other heat source except for laser beams. Therefore, the problem of deformation of workpiece is avoided under the action of heat. The laser welding speed is fast, and the processing process can be accurately controlled. At the same time, because the welding wire does not contact the surface of the workpiece during laser welding, an oxide film.
Because laser welding is completed by the interaction between laser beams from high -power laser and the welding metal, it will not cause pollution to the surrounding environment. So for aluminum and copper, such as aluminum and copper, laser welding is a good choice.
● Simple welding technology, easy to achieve automation and mechanization
Compared with other welding methods, laser welding has other unparalleled advantages. If non -contact welding is used, it can be used for welding of thin -walled materials. Laser welding is particularly suitable for the connection of heterogeneous metals. It has the advantages of no welding residue, no welding, good melting, and beautiful weld forming.
