The traditional welding method takes a long time and has low efficiency. Therefore, in the mid-1980s, laser welding as a new technology received extensive attention in Europe, the United States, and Japan. But to talk about the development of laser welding in our country, we must start from 2002. On October 25, 2002, China's first specialized commercial laser welding blank production line was officially put into operation, which was introduced by Wuhan ThyssenKrupp's Chinese laser welding from Germany's ThyssenKrupp Group's TWB company. Since then, Shanghai Baosteel Arcelor Laser Welding Company and FAW Baoyou Laser Welding Co., Ltd. have successively put into production. In 2003, the first domestic large-scale strip online welding equipment provided by Huagong Laser passed offline acceptance. The equipment integrates laser cutting, welding and heat treatment, making China's Huagong Laser the fourth company in the world capable of producing such equipment.
