The rapid development of automobile industry is inseparable from advanced manufacturing technology. Laser welding, laser marking technology with high energy, high precision, high adaptability and other characteristics are widely used in the automotive industry, advanced laser welding technology, can improve the quality of welding, its welding joint strength is high, can

To reach the same strength as the base metal;

Welding features:

● laser welding equipment stable performance, good repeatability, high reliability, welding joints beautiful;

Because of the laser welding flat, the welder in the production process will not damage other parts.

Laser welding is a process in which materials are fused and joined by focusing high energy laser beam to form excellent welding joint.

With the introduction of the rigid requirements of the laws and regulations on automobile safety, the uniqueness of the identity of automobile and parts has been put forward very high requirements. The establishment of the identity of automobile and parts is the basis for the realization of product quality traceability and recall

The special and non-reusable nature of miscellaneous and label materials makes it difficult for counterfeiters to evaluate the labels of automobiles and parts, thus effectively protecting the legitimate interests of legitimate automobile and parts manufacturers and users.

Laser welding has become one of the important means in automobile manufacturing due to its advantages such as high energy density, small deformation, narrow heat-affected zone, high welding speed, easy to realize automatic control and no subsequent processing. There are hundreds of different parts in the body and chassis of a car. How to connect them

Together has a direct impact on the rigidity of the vehicle body, the use of laser welding almost all the different thickness, brand, type and grade of metal materials can be connected together, in the improvement of production efficiency and quality, but also increase the flexibility of automobile design and material selection. Laser welding

Welding is a process in which the material is fused and joined by focusing high energy laser beam to form an excellent welding joint.

Laser welding has the characteristics of fast welding speed, small deformation of workpiece, large weld fusion ratio, fine grain, simple post-welding treatment, good weld quality and so on.

Laser welding of automobile gear is a developing trend. At present, the world's major automobile manufacturers are competing to adopt laser welding gear, replacing resistance welding, induction welding, electron beam welding and other technological methods, in order to improve the competitiveness of products in the international market.

Laser welding gear does not need to be carried out in vacuum, can avoid welding deformation, after the welding of the gear does not need to be refined, gear welding can not only reduce the number of parts, but also improve the quality of the gear, reduce the manufacturing cost of the gear.

Laser welding can make the weld depth to width ratio up to 10:1, and the weld has the same or better than the base material's comprehensive mechanical properties, to ensure that the gear can transfer a large torque.

The trunk consists of the trunk cover and the rear coaming, which is welded by laser brazing due to its 90 degree Angle. Traditional trunk with MlG brazing welding, because trunk material for galvanized sheet, usually adopts the MlG brazing low heat input to solve the problems brought by the galvanized layer of a large number of loss, but the MlG high-speed welding and brazing down small electric arc of instability limit its efficiency and quality of laser welding is mainly for welding complex forming or tangent to a sharp change of welding seam, smooth welding surface. In addition, it is difficult for MlG brazing to form smooth welds and the pollution is large. Using laser brazing, the welding speed is high, the weld is well formed, the quality is stable, the galvanizing layer burns less, and the deformation is small.
