Laser Robotics In Automobile Production Main Driver Of The Automobile Industry

　　In recent years, the rapid development of laser technology, emerging with the robot flexible coupling of fiber optic transmission of high-power industrial lasers. Advanced manufacturing in the field of intelligence, automation and information technology continues to progress to promote the combination of robotics and laser technology. In particular, the development needs of the automotive industry, driven by the formation and development of the laser processing robot industry.So, I believe laser welding machine In the future, it will be promising to create a miracle belonging to the industry. https://riselaser.net/products/laser-welding-machine

　　

　　1.Robotic Laser Welding

　　

　　The automotive industry is the largest industrial application of laser processing robots. In modern automobile manufacturing, robot welding is an important welding process on the automobile production line. In recent years, with the rapid development of laser welding technology. Many automobile manufacturers around the world began to assembly line with robotic laser welding instead of the traditional spot welding technology, for body welding and parts welding.

　　

　　In the mid-1990s, BMW used a laser robot to complete the first weld in the BMW 5 series sedan with a total length of 12 m. By July 2003, the total length of laser welded seams had accumulated to 1,500 km. Volkswagen in Germany used 1,400 laser welded joints in the Touran sedan with a total length of 70 m. The roofs of Audi A6, Golf A4, Passat, etc. are all laser welded. Audi A6, Golf A4, Passat and other brands use laser welding on the roof. General Motors also uses laser welding on the top of the frame.

　　

　　Compared with traditional welding methods, laser welding has many unique advantages. Laser welding speed, up to 20 m/min; welding deformation is very small, high precision welding; welded joints of high metallurgical quality, improve the fatigue resistance of the body, impact resistance, corrosion resistance, body steel degree increased by more than 30%; improve the sealing of the body, reduce noise by 30%; single-sided welding, welded joints, the size of the small, small welding edges of the reserved.Therefore, laser welding not only greatly improves the automobile production efficiency, production quality and safety of the body. Moreover, it lightens the weight of the whole car and reduces the cost of automobile production. In addition, it belongs to the non-contact welding, flexible production, body design more of a modern concept.

　　

　　2.Robotic Laser Cutting

　　

　　In all laser processing, laser robot cutting technology is the earliest used in foreign automobile production. Volkswagen, General Motors, Mercedes-Benz and Nissan have installed a large number of laser cutting robots on their automobile production lines to cut parts of the body to meet the customer¨s multi-variety and humanized use requirements.

　　

　　3.Robotic Laser Thermal Processing

　　

　　In order to solve the needs of on-line or on-site production of automobiles, a few companies have developed laser heat treatment robots in recent years and have successfully applied them in the automotive industry. Germany Erlaser laser heat treatment robot for automotive large mold laser broadband quenching. The use of semiconductor lasers single quenching width of 20 mm. this SAIC-GM-Wuling Automobile Co., Ltd. and Liuzhou Cole digital manufacturing technology limited company also used this technology. The results show that the life of the mold has doubled and the quality of the product has improved significantly and therefore the productivity has increased significantly.
