Fiber laser welding machine principle and structure！

Fiber laser welding machine is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has high depth-to-width ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need for post-welding treatment or only simple treatment, and high weld quality.

Fiber laser welding machine is widely used in smart phone communications, myopia glasses clocks, jewelry decorations, hardware products, high-precision equipment, auto parts, craft products and other fields. Fiber laser welding machine equipment can be used for welding various metal materials such as titanium, nickel, zinc, copper, aluminum, chromium, niobium, gold, silver, and aluminum alloys, steel, Kovar aluminum alloys and other alloy products.

Working principle of fiber laser welding machine:

Fiber laser welding machine is a kind of laser welding equipment that couples high-energy laser beam into optical fiber, transmits it over a long distance, collimates it into parallel light through a collimator, and then focuses it on the workpiece to perform welding. It performs flexible transmission and non-contact welding on parts that are difficult to access for welding, which has greater flexibility. The laser beam of the fiber laser welding machine can achieve time and energy splitting, and can perform multi-beam processing at the same time, providing conditions for more precise welding.

Fiber laser welding machine can be divided into pulse laser welding and continuous laser welding according to the different output modes of laser beam. According to the formation characteristics of weld seams during laser welding of fiber laser welding machine, laser welding can be divided into thermal conduction welding and deep fusion welding. The former has low laser power, long molten pool formation time and shallow fusion depth. It is mostly used for welding small parts; the latter has high laser power density, fast metal melting speed in the laser radiation area, and strong vaporization at the same time as the metal melting, which can obtain weld seams with large fusion depth and large depth and width of weld seams, and can be selected as 12:1.

Fiber laser welding machine composition structure:

1. Laser system: laser, laser power supply, laser control card, optical path and other main parts.

2. Cooling system: Because the laser welding machine operates at high power and generates high-energy heat during operation, the cooling system can cool the laser. The power of the chiller equipped with different powers is different.

3. Workbench cabinet: The workbench is a stainless steel table, and the table space can include a bracket for placing the display and measuring instruments; the volume is small, and the table layout can be determined according to user requirements, such as installing a manual lifting mechanism.

4. CCD real-time observation system: The laser welding spot can be observed at any time, and the running trajectory has been observed.

5. Installing automation equipment system: The fiber laser welding machine can cooperate with three-axis, four-axis linkage workbench, manipulator, and cantilever workbench to achieve precision welding motion trajectory control.

In short, it is composed of the above systems. If you want to know more about fiber laser welding machine, you can contact SAN LASER at any time. The professional answer will definitely satisfy you.
