The car has become an indispensable means of transportation for people. With the consumers’pursuit of individuation and function quality, the automobile manufacturing industry is becoming more and more competitive, introducing new products to meet the public’s demand for function and appearance. But the life of cars is getting shorter and shorter, so the main challenge for manufacturers is how to improve the quality of the manufacturing process while achieving short cycle, low cost, high reliability and efficient use of materials.
By halving the quality of cars, fuel consumption could be cut almost in half. Safety: In theory, the impact energy from a car crash is proportional to the car’s mass. Under the same conditions, the lighter the vehicle, the smaller the collision energy, the better and safer the protection performance of the passengers. In fact, as long as the structure design, material selection and connection mode of the collision absorption zone are reasonable, the vehicle can achieve excellent passive safety.
As a high tech industry, car making is a huge systems engineering. But because laser welding technology has high productivity and is widely used in automobile manufacturing process and automobile parts production and processing, laser welding is of great significance to the innovation of processing technology, and laser welding is flexible, can be processed in a variety of shapes and materials. Compared with the previous welding method, in the application of new materials such as aluminum alloy, magnesium alloy and titanium alloy, the materials that are difficult to be processed can be realized because of its high efficiency, precision and advanced manufacturing technology, the production cost of the enterprise is greatly reduced and the production efficiency and quality of the enterprise are improved. It also makes possible the application of these new materials from ideal to reality, thus making it possible for cars to be lightweight.
The laser welding technology, which plays an important role in promoting the lightweight of automobiles, not only greatly improves the mechanical properties and safety of automobiles, but also makes an important contribution to environmental protection on a global scale, it has a wide application prospect in the field of automobile. The improvement of the overall competitiveness of China’s automobile manufacturing industry and the country’s emphasis on manufacturing will effectively promote the development of China’s automobile-related manufacturing industry.
