Laser welding machine manufacturers
Laser welding machine manufacturers believe that laser welding is a mature technology widely used in automobile body manufacturing in developed countries. Automotive body-in-white robot laser welding technology is used to replace traditional resistance welding technology. It can not only improve the welding quality and mechanical properties of body parts, but also save materials and greatly reduce the cost of body manufacturing.
Laser welding machine manufacturers believe that compared with other welding technologies, the main advantages of laser welding are:
Laser welding has the advantages of high speed, large depth, small thermal deformation, no tool wear, no cutting force on the workpiece, and small subsequent processing volume.
It can be welded under normal temperature or special conditions, and the welding equipment is simple. For example, when a laser passes through an electromagnetic field, the beam does not move. Lasers can weld in vacuum, air, and certain gas environments, and through glass or materials that are transparent to the beam.
Laser welding machine manufacturers believe that the power density after laser focusing is high, the aspect ratio can reach 5:1, and the height can reach 10:10.
It can weld refractory materials such as titanium and time, and can weld dissimilar materials with good effect.
Micro-welding is possible. Laser welding machine manufacturers believe that after focusing the laser beam, a small spot can be obtained, which can be positioned. It can be applied to the assembly and welding of small and medium-sized parts in large-scale automatic production, which not only greatly improves the production efficiency, but also has a small heat-affected zone, no pollution to the solder joints, and greatly improves the welding quality.
It can weld hard-to-reach parts and realize flexible non-contact long-distance welding. Especially in recent years, the application of optical fiber transmission technology in YAG and fiber laser processing technology has made laser welding technology more widely promoted and applied.
Laser welding machine manufacturers believe that the laser beam can be easily divided by time and space, and multiple beams and multi-station processing can be processed at the same time, which provides conditions for welding.
Radium welding machine manufacturers believe that robot laser welding technology has been widely used in automobile body manufacturing in developed countries, and replacing traditional welding technology can not only improve the welding quality and mechanical properties of automobile body parts, but also save materials and greatly reduce body manufacturing costs. World-renowned automobile companies have adopted robotic laser welding technology to produce bodywork.
Laser welding machine manufacturers believe that laser welding, laser brazing and laser hybrid welding have been successfully applied to body-in-white welding, including welding body-in-white doors, side walls, front walls, rear walls, floors and roofs. The joint forms such as lap joint, butt joint and fillet joint realize the effective welding of aluminum, high-strength steel and high-strength galvanized steel. It can not only reduce the material consumption and weight of the body, but also greatly improve the strength and rigidity of the body. Therefore, domestic automakers also hope to apply laser welding technology to body manufacturing. However, due to the backward technology and equipment, it is unable to independently research and develop, and can only rely entirely on imports. Therefore, it is necessary to conduct in-depth research on laser welding technology, equipment, and the design and modification of body structures.
