High Frequency Nanosecond Fiber Laser Precision Welder-SFM70 As a nanosecond fiber laser, SFM70 has MOPA configuration with a maximum frequency of 1000 kHz and high peak energy. With pulse mode and continuous welding mode, it’s a mixed type welding (take advantages of both heat conduction welding and deep penetration welding) can generate a variety of waveforms and accurately control the heat input into the material. This model is widely applied in thin plate materials welding (below 0.2mm), reflective elements (copper alloy, aluminum alloy, gold) and dissimilar metal welding. The solder joints of the products are well formed, uniform in size, and the tensile shear strength are significantly improved compared with YAG and millisecond fiber lasers. Features ● The average output power ~70W ● The pulse width reaches nanoseconds level, the repetition frequency is up to 1000kHz ● Precisely controlled, small laser spot, assisted by CCD camera vision capture system for high-precision positioning, easy to achieve automation
● High electro-optical conversion efficiency, can be as high as 25%, energy consumption is extremely low
● Optical device has a long service life and is maintenance-free ● Tiny laser spot can be precisely positioned and easily automated |
