What Are The Advantages Of Fiber Laser Welding Machine?

Fiber Laser Welding Machine is a laser welding equipment that uses fiber laser as the light source. It mainly consists of laser, power supply system, optical workbench, cooling system and control system.
1. Laser: Fiber laser is the core part of fiber laser welding machine. It can produce high-energy, high-brightness laser beam to provide necessary energy for welding.
2. Power supply system: The power supply system mainly provides power for the laser to ensure the normal operation of the laser.
3. Optical workbench: The optical workbench is used to fix the workpiece and can move in three dimensions to facilitate laser welding operations.
4. Cooling system: The cooling system is mainly used to cool the laser and the workpiece to prevent overheating from affecting the welding quality or damaging the equipment.
5. Control system: The control system is responsible for the operation control of the entire equipment, including laser power control, welding speed control, welding path control, etc.

Working principle of fiber laser welding machine:
First, a high-energy laser beam is coupled into an optical fiber through a laser, and then transmitted over long distances through the optical fiber. In this step, the laser is the core part of the fiber laser welding machine. It generates a high-energy, high-brightness laser beam to provide the necessary energy for welding.
Secondly, the transmitted laser beam is collimated into parallel light by a collimating mirror, and then focused on the workpiece for welding. In this process, the optical workbench plays a role in fixing the workpiece and can realize three-dimensional movement to facilitate the laser welding operation.
In addition, the laser welding machine also has the ability to split light in time and energy, and perform multi-beam simultaneous processing. This feature makes the fiber laser welding machine more flexible and can adjust the laser power and welding speed according to actual needs.
Finally, after the welding is completed, the laser welding machine cools the laser and the workpiece through the cooling system to prevent overheating from affecting the welding quality or damaging the equipment.
In general, fiber laser welding machine is an efficient, high-quality, high-precision welding equipment suitable for welding of various materials.

Advantages of fiber laser welding machine:
1. High precision: Fiber laser welding machines can achieve micron-level precision welding to meet the needs of high-precision welding.
2. High efficiency: Due to the high photoelectric conversion efficiency of fiber lasers, which is as high as 30%, which is 10 percentage points higher than traditional gas lasers, the working efficiency of fiber laser welding machines is much higher than that of traditional welding methods. .
3. Good quality: The beam quality output by the fiber laser is close to the ideal value and can be focused to a very small spot size, thereby achieving precision welding. The fiber laser welding machine can achieve deep penetration welding, small heat-affected zone, smooth and beautiful welds, ensuring welding quality. The service life of fiber lasers can reach more than 100,000 hours, far exceeding that of gas lasers.
4. Good flexibility: The system is small in size and light in weight. There is no huge water cooling system. The size and weight of fiber lasers are much smaller than gas lasers, making them easy to integrate and install. The fiber laser welding machine can adjust the laser power and welding speed as needed to adapt to various welding needs.
5. Environmental protection: The power consumption of fiber lasers is only about half of traditional gas lasers, which is energy-saving and environmentally friendly. Moreover, fiber laser welding is a non-contact processing method. Fiber laser does not require high-pressure gas sources and chemical assistance, has no radioactive pollution, is safe and reliable to use, and meets environmental protection requirements.

According to statistics, there are more than 100 laser welding production lines for tailoring blanks worldwide, with an annual output of 70 million pieces of tailor-welded blanks for passenger cars. In addition, the fiber optic continuous laser welding machine can be used to weld car body structural parts such as roofs, doors, and hoods to improve the strength and sealing performance of the car body. At the same time, it can also be used for welding automobile parts.
B. Medical field: In the medical field, fiber laser welding machines can be used in the manufacture of medical devices, such as surgical instruments, orthopedic implants, etc. Due to its high precision, small heat-affected zone, and smooth and beautiful welds, it is very suitable for precision welding of medical devices.
C. Other fields: Fiber laser welding machines can also be used in the electronics industry, aerospace industry, etc. For example, it can be used for welding mobile phone batteries, electronic components, etc.; in the aerospace field, it can be used for welding aerospace engine impellers, turbine blades, etc.
