Fiber laser welding system
Optical fiber transmission laser welding machine is a kind of laser welding equipment that couples high-energy laser beam into optical fiber, and after long-distance transmission, it is collimated into parallel light by a collimator, and then focused on the workpiece to perform welding. For parts that are difficult to be welded, the flexible transmission non-contact welding is implemented, which has greater flexibility. The laser beam of the optical fiber transmission laser welding machine can realize the splitting of time and energy, and can process multiple beams at the same time, which provides conditions for more precise welding.
Main feature
The optical fiber transmission laser welding machine is equipped with a CCD camera monitoring system, which is convenient for observation and precise positioning.
The energy distribution of the welding spot of the optical fiber transmission laser welding machine is even, and it has the best spot required for welding characteristics.
The optical fiber transmission laser welding machine is suitable for various complicated welding seams, spot welding of various devices, and seam welding of thin plates within 1mm.
The optical fiber transmission laser welding machine adopts a ceramic condenser cavity imported from Britain, which is corrosion-resistant and high-temperature resistant. The cavity life is (8-10) years, and the life of the xenon lamp is more than 8 million times.
Dedicated automatic tooling fixtures can be customized to achieve mass production of products.
Application
Optical fiber transmission laser welding machine is used for precision welding of optical communication devices, IT, medical treatment, electronics, batteries, optical fiber coupling devices, kinescope electron guns, metal parts, mobile phone vibration motors, precision parts of clocks and watches, automotive steel sheets, etc.
Application field
Manufacturing applications
Laser welding machines are widely used in automobile manufacturing at home and abroad. In Japan, CO2 laser welding machine was used to replace flash butt welding for the connection of rolled steel coils in the steel industry. In the research of ultra-thin plate welding, such as foils with a thickness of less than 100 microns, there is no way to weld them, but through YAG laser welding with a special output power waveform was successful, showing the broad prospects of laser welding.
Powder metallurgy field
With the continuous development of science and technology, many industrial technologies have special requirements for materials, and materials manufactured by traditional technologies can no longer meet the requirements. The laser welding machine enters the field of powder metallurgy material processing, bringing new development prospects for the application of powder metallurgy materials. For example, the brazing method commonly used in powder metallurgy material connection is used to weld diamond, because the bonding strength is low and the heat affected zone is wide. It is unable to adapt to high temperature and high strength requirements, causing the solder to melt and fall off. The use of laser welding machine can improve the welding strength and high temperature resistance.
electronics industry
Laser welding machines have been widely used in the electronics industry. Because laser welding has a small heat-affected zone, rapid heating concentration, and low thermal stress, it has shown unique advantages in the packaging of integrated circuit and semiconductor device housings. Laser welding has also been applied in the development of vacuum devices. The thickness of the elastic thin-walled corrugated sheet in the sensor or thermostat is 0.05-0.1mm, which is difficult to solve with traditional welding methods. TIG welding is easy to weld through, plasma stability is not good, and there are many influencing factors. Laser welding has a good effect. It is widely used.
auto industry
Nowadays, the laser welding machine production line has appeared on a large scale in the automobile manufacturing industry and has become one of the outstanding achievements of the automobile manufacturing industry. Many automobile manufacturers use laser welding and cutting processes. High-strength steel laser welding assembly parts are increasingly used in automobile body manufacturing due to their excellent performance. Because of the large volume and high degree of automation in the automotive industry, laser welding equipment will develop in the direction of high power and multiple channels.
