Application of fiber laser welding machine
Fiber laser welding machine is a laser welding machine that couples a high-energy laser beam into an optical fiber, transmits it over long distances, collimates it into parallel light through a collimating mirror, and then focuses on the workpiece for welding. The laser beam is then collimated to parallel light by a collimating mirror and focused on the workpiece to be welded. The laser beam is flexible and non-contact welding for parts that are difficult to access. Fiber transmission laser welding machine laser beam can realize time and energy splitting, and can carry out multi-beam processing simultaneously, providing conditions for more precise welding.
Fiber transmission laser welding machine is widely used for precision welding of optical communication devices, IT, medical, electronics, batteries, fiber optic coupling devices, video tube electron guns, metal parts, cell phone vibration motors, precision parts of clocks and watches, automotive steel pieces, etc.
Powder metallurgy field
Science and technology continue to develop, many industrial technologies have special requirements for materials, the traditional technology to manufacture materials can no longer meet the requirements. Laser welding machine into the field of powder metallurgy material processing, for example, the application of powder metallurgy materials to bring new prospects for development, such as the use of powder metallurgy materials commonly used in the connection of brazing method of welding diamond, because of the low bond strength, heat-affected zone is wide, especially can not adapt to high temperature and high strength requirements and caused by the melting off of brazing material, the use of laser welding machine can improve the welding strength and high temperature resistance performance.
Electronics industry
Laser welding machines are widely used in the electronics industry. Because laser welding heat-affected zone is small, the heating concentration is rapid and the thermal stress is low, thus is in the packaging of integrated circuits and semiconductor device shells, showing unique superiority, in the development of vacuum devices, laser welding has also been applied. Sensors or temperature controllers in the elastic thin-walled corrugated sheet thickness in 0.05-0.1mm, using traditional welding methods is difficult to solve, TIG welding easy to weld through, plasma stability is not good, the impact of many factors and the use of laser welding effect is very good, widely used.
Automotive industry
New energy buses and cars have been applied to the actual life, new energy vehicles reflect its high technology for the power battery, in order to ensure the stability and sustainable use of new energy batteries, the use of laser welding has become the inevitable choice in the field of power batteries. Laser welding machine is mainly used in the welding of power battery module connection piece.
The new energy field power battery cells follow the principle of "lightweight", the material used is thin aluminum alloy, battery shell, cover and bottom are basically required to reach 1.0 mm below, the mainstream manufacturers are currently the basic material thickness of about 0.8 mm, laser welding to meet the requirements of welding ultra-thin power battery.
Laser welding for power battery welding is the use of high-energy laser pulses on the power battery for local heating of tiny areas, the laser radiation energy through heat conduction to the internal diffusion of the material, the material melted to form a specific melt pool. It can realize spot welding, butt welding, stack welding, seal welding, etc., with high depth ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld seam, power cell and other products after welding without treatment or only simple treatment, high quality weld seam, no porosity, controllable, small focused spot, high positioning accuracy, easy to realize automation.
