Laser welding machines can be divided into fiber laser welding machines, handheld laser welding machines, jewelry laser welding machines. Among them, a fiber laser welding machine is a kind of laser welding equipment that couples a high-energy laser beam into an optical fiber, and after long-distance transmission, it is collimated into parallel light by a collimator. Next, let's take a look at the introduction of fiber laser welding machines. Here are some answers.

What is a fiber laser welding machine?

The fiber laser welding machine implements flexible transmission and non-contact welding for parts that are difficult to access, which has greater flexibility. Fiber laser welding machine the laser beam can realize time and energy splitting and can process multiple beams at the same time, which provides conditions for more precise welding. The 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, etc.

What are the advantages and principles of fiber laser welding machines?

First, the fiber laser welding machine can output multiple optical fibers, which can realize energy splitting, and evenly distribute the laser energy output by the laser to each output fiber; it can also realize time splitting, and output the laser energy to each channel in sequence at different time intervals. Second, the laser of the fiber laser welding machine is transmitted in the form of total reflection in the optical fiber. During the transmission, the optical fiber will homogenize the uneven position in the spot, and the spot formed at the output end of the fiber is a relatively uniform' light spot. Third, the laser has a thermal lens effect, which changes the beam spread angle of the laser output. If the laser is output by a hard optical path, the focal length of the laser is changed. To reduce this change, the output of the hard optical path is generally focused on after beam expansion. But if it is output by optical fiber, the divergence angle of the laser depends on the numerical aperture of the optical fiber, and the focus of the laser output is constant.

Fourth, the fiber laser welding machine can output the laser to the place where welding is needed. With the manipulator, it can achieve continuous laser welding of complex spatial curves to meet the needs of customers. Fifth, the energy feedback of the fiber laser welding machine is to take a part of the laser and compare the difference before and after the output energy and control the laser in a closed loop to stabilize the laser output. Energy feedback is a dynamic closed-loop control, which can keep the laser output from being affected by the aging of the xenon lamp. When the xenon lamp energy is insufficient, the power output will be automatically increased to maintain the stability of the laser; if the xenon lamp is attenuated and unable to be used, the customer will be automatically prompted to replace the xenon lamp. Sixth, whether the fiber laser welding machine is a mirror frame or a condenser cavity, the use time is generally a few months. When the equipment is continuously used and vibrated, the alignment of the lens will be reduced. If the energy output is weakened, the light path should be adjusted slightly to restore energy output. Energy feedback can improve the output of the laser to a certain extent. When the alignment of the lens drops, it will automatically replenish energy.
