Decrypt the application of laser technology for lightweight cars

Views:0     Author:hu     Publish Time: 2021-09-11      Origin:dapeng

With the tightening of fuel consumption and emission regulations and the rapid increase in new energy vehicles, vehicle lightweighting has become the focus of all vehicle manufacturers. At present, automobile lightweight can be achieved from three aspects: optimized structural design, lightweight materials and advanced technology, and improvements in these three aspects are inseparable from the support of laser technology.


In fact, in the automobile manufacturing industry, the application of laser technology is extremely common, especially the most common applications of laser cutting and welding. To some extent, it has become a tool that meets industry standards.


In terms of the three ways to achieve automobile lightweight, firstly, in optimizing the body structure design, the use of unequal-thickness plates is currently the most mature and most widely used method, and unequal-thickness plates need to be realized by laser tailor welding; secondly, In terms of material use, currently the most commonly used lightweight materials are thermoforming and aluminum alloy. Because of the high hardness of thermoforming materials, laser cutting and trimming are required. The best way to weld aluminum alloy is laser; finally, in the body In the connection process between parts, the use of laser welding can reduce the width of the flange and reduce the weight. At the same time, other parts of the car body, such as seat welding, are increasingly using laser welding to achieve lighter weight.


Various signs indicate that laser has become an indispensable tool in the field of automobile manufacturing.
