With the rapid development of the medical industry, laser welding technology also has a huge market application space on the road of helping medical devices. Compared with other common welding technologies, laser welding technology produces almost no welding slag and debris, and there is no need to add any adhesive in the welding process, so the whole welding work can be completed in the clean room. At present, in addition to the application of laser welding technology in the production of medical equipment, there are many other laser processing technologies in the manufacturing of medical equipment, such as laser surface modification, laser cutting, laser drilling and laser micromachining.
