Recently, the World New Energy Vehicle Conference (WNEVC) was held in Boao, Hainan. With the theme of "New Era, New Transformation and New Industry", this conference focused on automobile transformation development strategy, technological innovation and reform. Under the wave of the new generation of technological revolution, automobiles are gradually becoming electrified, intelligent, and shared. The global automobile industry is entering a major transformation that has not been seen in a century. For the upstream and downstream industrial chains of the automotive industry, huge new opportunities for development have come.
Whether it is in the manufacturing process of fuel vehicles or new energy vehicles, the welding of the car body in white is an important link in the car production process. The welding quality of the body in white is directly related to the quality of the vehicle And service life.
Since the German Volkswagen factory took the lead in adopting laser welding of body-in-white in the 1980s, body-in-white laser welding has been widely used in automobile manufacturing. In some European and American auto manufacturers, body-in-white laser welding has become a A standardized processing technology, such as the welding of the roof and trunk lid of Audi cars has completely abandoned spot welding.
Laser welding has high energy density, small deformation, Narrow heat affected zone, high welding speed, easy to realize automatic control, no follow-upThe advantages of processing, abandoning the traditional welding method, adopting the body-in-white laser welding machine can effectively improve the efficiency of automobile manufacturing and reduce the cost of automobile production. The laser welding of the automobile body-in-white roof can be completed in less than 1 minute...
With the vigorous development of the domestic laser industry, some pioneering companies have begun to get involved in the field of automobile manufacturing. After several years of first-hand trials, now facing the era of laser welding of the body-in-white-domestic laser companies' "Chinese plan" has been fully implemented.
China’s pioneering laser company
At the Shanghai Auto Equipment Exhibition, Han’s Laser Intelligent Equipment Group held a product launch conference for intelligent welding line. At the press conference, Chen Yan, general manager of Han’s Laser Intelligent Equipment Group, said in his congratulatory speech: “Han’s Intelligent Equipment Group laser welding products have been Efforts, widely used in the auto parts industry and OEMs, and won unanimous praise from users (such as typical users: SAIC GM, FAW Group, BYD, Lear China, Faurecia China, Magna China, etc.). In order to fully serve the various welding technology needs of customers in the automotive industry, we acquired Shenyang Saitewei, an arc welding equipment manufacturer in 2015.Energy and internationalization have taken a more solid step. In the future, it will provide overall solutions for welding and assembly for the automotive industry. ”
At the same time, HG Laser also launched the first domestic "automobile body-in-white welding production line", which has been applied to General Motors, Jianghuai, JianglingFord, Guangben and other multi-brand and multi-model vehicles account for 90% of the domestic automotive body-in-white welding business. The laser welding production line for the top cover of Guangzhou Automobile Honda's tenth generation Accord. This production line currently has the fastest domestic production cycle (one unit in 43s).
The quality of the car itself is reduced by 1%, fuel consumption can be saved by 0.6%-1.0%, and its acceleration performance will be greatly improved. Laser welding can not only compress the body structure The volume of parts, the weight of the car body, and the energy loss can be reduced. It can also reduce the loss of process and production materials and improve production efficiency.
Today, the sustainable development of the automotive industry will be important to promote the sustainable growth of the global economy in the future Engine, laser as advanced manufacturing technology,Will continue to promote the technological innovation and upgrading of the automobile manufacturing industry. In the future, more Chinese laser companies will join the camp!
