How is FAW Audi's brand-new a4l made?

How is the new Audi A4L made? After the brand-new Audi A4L went on the market, it was widely recognized by the market and consumers. At present, A4L is in a state of brisk sales in short supply. So how is the new Audi A4L made? Recently, the reporter visited Changchun FAW-Volkswagen Factory and experienced the production line of Audi A4L. Now I will share the proceeds with netizens. Highlight 1: Vehicle odor laboratory? FAW-Volkswagen has the most advanced vehicle odor laboratory in China. In order to strictly monitor the smell of the whole vehicle, the laboratory staff regularly select commercial vehicles as experimental samples and put them into the vehicle smell laboratory. Under conditions worse than the actual use environment, the whole vehicle is sealed for 16 hours. Then the air inside the car was extracted by sampler, and the contents of volatile organic compounds and aldehydes and ketones in the air inside the car were analyzed by gas chromatography and liquid chromatography. Through accurate detection and scientific evaluation, the odor emission of new cars is ensured to meet the national standards of Europe and China. ? Highlight 2: electrical laboratory? With the continuous development of automotive electronic technology, electronic and electrical components have become an important part of the entire automotive system. Unlike other parts, the electronic and electrical system cannot directly detect the quality, and it must be detected by special instruments. The electrical laboratory was built for this purpose. The electrical laboratory adopts EMB(electronic Meisterbock) network, just like a car that can be disassembled at will. Each part of it, including controller, sensor, execution unit and signal unit, can be analyzed and diagnosed separately. Through the simulation drive of some functions, possible problems in actual operation can be found early and eliminated in time. ? Highlight 3: Plasma Brazing Technology The new Audi A4L has also used plasma brazing technology for the first time in China. This advanced welding technology can fully melt the material by producing powerful plasma beam, and the deformation of the parts is small, which can effectively ensure the flatness quality of the car body surface. The direct effect of this is to further improve the smoothness of the vehicle surface and strengthen the strength of the body. As a pioneer of domestic high-end cars, Audi brand has never let users down in appearance and workmanship. In the final analysis, it comes from the application of these leading technologies. It is worth mentioning that through the adoption of new technology, the number of workers in the side rail welding station has been greatly reduced from more than 160 to more than 10, and the labor efficiency has been greatly improved. Highlight 4: Automatic robot spot welding technology As the most mature production base of high-end cars in China, robot spot welding technology has been widely used in Audi welding workshop. More than 6,700 solder joints in the whole vehicle are completed by robots, and each group of robots will complete more than 800 solder joints on average. Automatic production process not only reduces the labor intensity of workers, but also further improves the control of welding quality. The welding workshop has strict regulations on the handling of defective products, and the car body is inspected in all directions through the size monitoring measurement with the accuracy of 0.1mm. Under any circumstances, the unqualified welded car body must be directly cut and destroyed to eliminate the defects from the source. ? Highlight 5: Audi with details above everything else? During the whole visit, what impressed me most was that Audi was obviously superior to its competitors. The purpose of setting up the Audi link of the whole vehicle is to treat those qualified vehicles that have passed the 100% vehicle inspection line as works of art for all-round appreciation and criticism. In the field of art, there is no perfection, only better, and the same is true in the field of automobile manufacturing. Audi judges, like those art connoisseurs, conduct random sampling quality evaluation activities on qualified vehicles according to the unified standards for vehicle quality evaluation formulated by the German headquarters. Users will inevitably complain about the products in their daily use. Different product complaints have different effects on different users, and the same type of complaints have different effects. Audi evaluation of vehicles is not a re-inspection of qualified products. It only evaluates the quality status and changing trend of products according to the evaluation standards and the grades and scores of product quality complaints, and provides information on whether products can be improved. If any quality defects are found, we will pay special attention to some related models and take corresponding quality actions to avoid possible problems in use.
