Application of laser welding machine in automotive manufacturing

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 automobile manufacturing.


Laser welding machine in seamless welding makes the structural precision of the bodywork is also greatly enhanced. When the car is running due to the bumpy ground extrusion, each 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 improved by more than 50% compared to other welding processes, reducing the noise and vibration during driving, improving the comfort of the ride, and also enhancing 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: In-line 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 cover laser welding and frame laser welding; another important body laser welding application is the laser welding of structural body parts (including doors, body side frames and pillars, etc.). The reason for using laser welding is that it can improve the strength of the body and can solve the difficulties of implementing conventional resistance spot welding in some parts.


3. Gear and transmission parts welding. In addition, a variety of parts of the transmission can be completed on this equipment welding process, especially the differential case and drive shaft in the car transmission, 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 adopts robot intelligent operation, and focuses on the workpiece by collimating parallel light through collimating mirror to implement welding as a laser equipment. With a simple universal instrument, it can weld precision parts that are difficult to access to large molds and implement flexible transmission non-contact welding, with greater flexibility in operation.
