Nowadays, laser welding has become a trend in the production of automobile body. The use of laser welding in automobile manufacturing can not only reduce the weight of the body and improve the assembly accuracy of the body, but also greatly strengthen the strength of the body. Provide higher security. The following is an introduction to the application of laser welding machine in the field of automobile manufacturing.

The precision of the structure of the car body is also greatly improved when the laser welding machine is seamlessly welded. When the car is driving, due to the bumps and squeezing of the ground, every component and structure is subjected to varying degrees of impact, which requires a high precision and strength of the overall structure of the car. With the current laser welding technology, its dynamic and static stiffness can be increased by more than 50% compared with other welding processes, reducing noise and vibration during driving, improving ride comfort, and improving the safety performance of the car.

1. Unequal thickness laser tailor-welded blanks: The use of unequal-thick laser tailor-welded blanks for body manufacturing can reduce body weight, reduce the number of parts, improve safety and reliability, and reduce production costs;

2. Body welding: Online laser welding in the automotive industry is widely used in the assembly and connection of body stamping parts. The main applications include laser welding of car roof covers, luggage lid laser welding and frame laser welding; another important laser welding application of car body is the laser welding of car body structural parts (including doors, body side frames and pillars, etc.) . The reason for using laser welding is to increase the strength of the car body and to solve the difficulty of conventional resistance spot welding in some parts.

3. Welding of gears and transmission parts. In addition, various parts of the gearbox can be welded on this equipment, especially the differential case and drive shaft in the car gearbox, which are often joined and welded after the individual parts are produced. Become.

The above is the application of laser welding machine in the field of automobile manufacturing. The laser welding machine for auto parts adopts the intelligent operation of robots, collimating parallel light through a collimator, and focusing on the workpiece to perform welding. With a simple universal instrument, it can perform flexible transmission and non-contact welding for welding precision parts that are inaccessible to large molds, which has greater flexibility in operability.
