Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding device with a protective mirror. Background Art

[0002] Laser is considered to be an ideal heat source for welding. Laser welding is one of the most important applications of laser technology. It uses polarizers to reflect the laser beam to concentrate it in a focusing device to generate a huge energy beam. It is a processing technology that uses the characteristics of the interaction between laser beam and matter to weld materials (including metals and non-metals). Laser welding has the characteristics of concentrated heating, less heat input, small deformation, fast welding speed (up to several meters to more than ten meters per minute), large welding depth-to-width ratio, and high quality. It is not only suitable for conventional materials, but also particularly suitable for refractory metals, heat alloys, titanium alloys, dissimilar metals with large differences in thermal physical properties, workpieces with large differences in volume and thickness, and components near the weld that are flammable, cracked, and exploded when heated. The weld is beautiful and beautiful. In many cases, the weld can be as strong as the parent material. Moreover, the laser beam can be transmitted through optical fiber, so the complex beam transmission system can be omitted, which is suitable for flexible manufacturing systems or remote processing. Laser welding can be either spot welding or continuous seam welding.
