Fiber laser welding machine advantages
Stable performance, fast speed, large depth, small deformation and good beam quality.
The welding equipment is simple and can be welded under normal temperature or special conditions. For example, if the laser passes through the electromagnetic field, the beam will not shift; Laser can stably weld in vacuum, air and some gas environment, and can weld through glass or materials transparent to the beam. The laser beam is easy to realize the beam splitting according to time and space, and can carry out multi beam simultaneous processing and multi station processing, providing conditions for more precise welding.
It can weld refractory materials such as titanium and quartz, and can weld dissimilar materials with good effect.
After laser focusing, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the maximum can reach 10:1.
Micro welding can be performed. Not only can the laser beam get a small spot after focusing, but also it can be positioned accurately and quickly. It is widely used in the assembly and welding of micro and small workpieces produced in large quantities of automation.
It is unique to weld the inaccessible fine parts, non-contact long-distance precise welding, with great flexibility and stability. The fiber transmission technology is adopted in the YAG laser processing technology, which makes the laser welding technology more advanced and more widely recognized and applied.
In the laser industry, fiber laser technology is widely used and gradually replaces the traditional hard optical path welding technology.
Fiber laser welding machine principles
Laser welding is the use of high-energy laser pulses to locally heat the material in a small area and carefully improve the material transformation. The energy of laser radiation is guided to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool.
Fiber laser welding machine is a new type of welding method, which is applied to the welding of precision parts and thin-wall materials, spot welding, seal welding, butt welding, overlap welding, etc. it has high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld, simple processing after welding, no gap, no air hole, no consumables, higher conversion efficiency, accurate control, small focus light spot, high positioning accuracy, automatic welding has been used.
