Abroad, Volkswagen uses laser welding on the roofs of Audi A6, Golf A4, Passat and other brands, while BMW and General Motors also use laser welding on the top of the frame. GM, Toyota, Ford, BMW, Fiat, Mercedes-Benz and Volkswagen all use laser tailor-welded blanks technology, while the three major American automobile companies and German Mercedes-Benz company use laser welding on the transmission parts. Volkswagen, GM, Mercedes-Benz and Nissan applied laser cutting technology, Fiat and Toyota used laser to coat engine exhaust valves, and Volkswagen's engine camshaft realized laser surface hardening treatment.

In China, high-quality vehicles from China, such as Passat, Buick, Audi, etc. All of them use laser tailor-welded blanks for laser welding, and the domestic laser welding technology has begun to change. In terms of laser welding technology (not laser welding), FAW-Volkswagen is in the forefront, and some domestic automobile manufacturers are gradually adopting this technology. At present, the application of laser technology in FAW, FAW-Volkswagen Audi A6 top cover and Bora back cover use laser welding, sagitar uses laser welding technology at the top and back cover of the car body, and the welding length reaches more than 30 meters. The equipment used by FAW is German Haas YAG 3KW laser and KUKA robot. Laser cutting of body parts of FAW Car Company: The equipment used is Arnold 3KW 3D five-axis CO2 laser processing machine in Germany. Laser hardening of brake shoes in FAW Chassis Accessories Factory: The equipment used is a domestic 2KW CO2 laser processing machine; Laser cutting of thin plate in faw mold center; And the equipment used is a domestic 1.5KW CO2 laser processing machine. With the maturity of laser welding technology and the decline of the price of laser welding machine, Chery automobile in China also began to adopt laser welding technology.
