Laser processing has become indispensable technology of the modern car manufacturing.
From the international point of view, the well-known car companies are scrambling to use
laser welding technology in the automobile body manufacturing, to ensure product quality
and advanced technology, remain invincible in the increasingly fierce competition, this trend
has been reflected in the domestic joint ventures. The United States, Germany are the
earliest to use high power Nd: YAG solid laser in automobile sheet metal gear cutting and
welding, shortening cycle of car modification from 5 years to 2 years, laser welding has
become a standard process in automobile industry. On the car body assembly lines, five-axis
laser processing machine or laser processing system of optical fiber transmission are
widely used in laser welding. Three major U.S. auto group (GM,Ford and Chrysler), European
auto firms (such as RENAULT, VOLVO, AUDI, BENZ and BMW company) ,on the production
line they adopt laser welding robot.Take GM for example,its online using laser more than 200
units. Germany Volkswagen, Audi A6, Golf A4, Passat all use laser welding.
