Application of Laser Technology in Automobile Industry

In recent years, with the continuous progress of science and technology, advanced manufacturing technology represented by laser technology is constantly promoting the upgrading and innovation of the automobile industry, and its application in automobile processing has become more and more extensive.
Compared with traditional manufacturing technology, laser technology has many advantages, such as non-contact processing, high precision, high flexibility, high efficiency, high automation and strong adaptability. In all kinds of functional parts or structural parts, there are laser processes such as cutting, welding, and marking. Laser processes such as cutting, welding, and marking are widely used in automobile frames, safety systems, interior and exterior trims, various functional parts or structural parts.
It is understood that in developed industrial countries such as Europe and the United States, 60% to 80% of auto parts are completed by laser processing.

1.Laser Cutting and Welding
Laser are widely used in automobile manufacturing as a new way of cutting and welding due to their high energy density, high precision, and strong adaptability. Laser cutting and welding technology give full play to its advanced, fast and flexible processing characteristics in the automotive industry. It is not only a technical guarantee for the development of new automotive products, but also an indispensable technical means for high-quality and low-cost production. And it is easy to integrate to automatic operating system, such as 3D robot fiber laser cutting machine and welding machine. It is also widely used in the production of modern automobile industry and has an excellent reputation for advanced cutting and welding methods. In the automobile industry of developed countries, laser cutting and welding technology used in automobile manufacturing has gradually become a standard processing technology.news-3
The application of laser cutting technology includes plane cutting and three-dimensional for metal and non-metallic sheets and pipes, such as hardware parts, body, door frames, trunks, roof covers, airbags, bumpers, central control panels, pillars, seat covers, carpets, etc.
The application of laser welding technology includes plane welding and three-dimensional welding for automobile body, roof cover, exhaust pipe, fuel injector, bumper, instrument panel, B-pillar, automobile battery pack, igniter and various sheet and pipe parts.

2.Laser marking
Laser marking is a marking method which uses a high-energy density laser to locally irradiate the product to vaporize or change the color of the material surface, thereby leaving a permanent mark, and no need to touch the product surface. Any special-shaped material can be quickly marked, and the product will not deform and generate internal stress. This is undoubtedly the best marking processing solution for the automotive industry that pursues efficiency and quality.

Laser machine can mark Chinese, characters, numbers, dates, graphics, qr code, bar code and on automobile signs, connecting rods, water pumps, pistons, piston rings, valve connecting rods, engine casings, gearboxes, springs, sealing strips, radiators, wipers, lights and other parts. And it can also mark the factory number, production number, factory name and trademark on the car body, frame, chassis, beam, etc. In addition, the laser marking machine can also draw accurate and efficient graphics and texts for various automotive interior products such as leather, cloth, wood, and synthetic materials.
The development of the automobile industry has put forward higher requirements for the automobile quality. Laser cutting, welding, marking and other technologies are not only superior to traditional processing methods in terms of processing quality, but also significantly improve the production efficiency. The laser technology is widely used in the field of automobile manufacturing and has played a vital role.
In recent years, with the expansion of global automobile market demand, while the process of automobile intelligentization is accelerating, advanced manufacturing technology represented by laser technology is also promoting the upgrading of automobile manufacturing industry. It is the general trend that the combination of advanced laser manufacturing technology and automobile production.
