Application of laser welding machine in automotive manufacturing

Nowadays, laser welding has become a trend in auto body production.

The use of laser welding in auto 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, providing higher safety for the users while they enjoy comfort. The following is an introduction to the application of laser welding machine in the field of automotive manufacturing.

Laser welding machine makes the structural precision of the bodywork also greatly improved when seamlessly welding. When the car is driving due to the bumpy ground squeeze, every part and structure is undergoing different degrees of impact, which requires the overall structural precision strength of the car to be very high. Using the current laser welding technology, its dynamic and static stiffness can be more than 50% higher than other welding processes, reducing the noise and vibration during the driving process, improving the comfort of the ride, but also enhance the safety performance of the car.

　　1. unequal-thickness laser welded panels: the use of unequal-thickness laser welded panels in body manufacturing can reduce the weight of the body, reduce the number of parts, improve safety and reliability and reduce production costs.

　　2. Body welding: online laser welding in the automotive industry is used extensively in the assembly and connection of stamped body parts. The main applications include roof laser welding, luggage compartment lid laser welding and frame laser welding; another more important body laser welding applications, is the body structure parts (including doors, body side frames and pillars, etc.) laser welding. The reason for using laser welding is to improve the strength of the body, and can solve some parts of the difficulty of implementing conventional resistance spot welding problems.

　　3. Gear and transmission parts welding. In addition, a variety of parts of the transmission can be completed in this equipment welding process, especially in the car transmission differential housing and drive shaft, etc., is often a single part of the production is completed and then joined and welded to each other.

　　The above is the application of laser welding machine in the field of automotive manufacturing. The laser welding machine for automotive parts is a laser equipment that uses robot intelligent operation and focuses on the workpiece by collimating parallel light through a collimating mirror to implement welding. With a simple universal instrument, it can implement flexible transmission and non-contact welding for the welding precision parts that are difficult to access by large molds, and has greater flexibility in operation.
