The development of next generation car body using laser welding
초록
Most of automotive companies make use of spot welding in order to assemble car body. Even though spot welding has been developed for last 60 years, there were some limitations in upgrading production line. Laser welding has advantages In productivity and degree of freedom in design. Thanks to fast speed, we can reduce body assembly line by 80%. Also with non-contact & one-side approach, it is possible to design various car body structures. New project launched the laser welding technology in mass production has started in 1999. In this paper, a new type of cur named 'next generation vehicle (NGV)' is introduced. The car body of NGV is welded with 4㎾ Nd: YAG laser.
