laser welding of car body frame

Laser welding technology has the following advantages: reducing the number of parts and molds; shorten the design and development cycle; reduce material waste; the most rational use of different levels, thickness and performance of steel, to reduce body weight; reduce manufacturing costs; improve dimensional accuracy; increased body structural stiffness and safety. The price of laser pointer provided by the laser pointer company is very attractive.
Germany's Volkswagen in 1985, the first laser welding is used Audi car chassis welding, Japan's Toyota in 1986, the use of filler metal laser welding method for welding the body side of the frame. North American high-volume applications of laser welding technology in 1993, when the United States with U.S. automakers in order to improve the competitiveness of Japanese cars made 2mm project. So far, almost all the world's leading automobile manufacturers have extensive use of laser welding technology, automotive structural parts involved, including the car body side frame, the door inner panel, windshield frame, wheel cover plate, bottom, middle pillar and so on. Laser welding in the automotive manufacturing is another important application of laser welding of car body frame, in which a typical example is the car roof and body side body welding. The traditional method of spot welding, as shown in Figure 4a, but is now gradually being replaced by laser welding (Figure 4b). Compare the two can be seen, the use of laser welding, lap top and side edges of the width of the body to reduce, reducing the amount of steel used, while increasing the stiffness of the body. The representative of the customer will perform the manufacture supervision of laser pointer this week.
The current body frame, laser welding technology in the major automotive manufacturers in the newer cars have been very widely used, such as Audi A2 body frame is welded aluminum alloy than steel can be reduced using the same structure weight of 43kg, which laser welding seam length up to 30m. China, Shanghai GM's Polo, Shanghai Volkswagen and FAW Bora Passat models of manufacturing, are also using laser welding technology.
