What is the working principle of the laser welding machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

The working principle of laser welding machines is mainly based on the high-energy characteristics of laser beams. The laser welding machine uses a laser as the core device to generate a laser beam through the laser. This laser beam has the characteristics of good monochromaticity, good directionality, and high brightness. When the laser beam is irradiated on the surface of the workpiece that needs to be welded, it will generate a high-energy heat source, causing the surface of the workpiece to melt, thereby achieving welding.
Specifically, the laser welding machine first converts the laser beam into a high-energy laser beam through a converter, and then precisely locates the laser beam to the position of the workpiece to be welded through an accurate robotic arm system. After the laser beam comes into contact with the surface of the workpiece, it generates sufficient high temperature to melt the workpiece and form a molten pool on the welded joint. The material in the molten pool undergoes metallurgical reactions under continuous laser beam irradiation, ultimately cooling and solidifying to form a weld seam.
The working process of laser welding machines can be adjusted and optimized through precise control systems to adapt to different materials and welding needs. By adjusting parameters such as laser power, welding speed, and focus position, precise control of welding quality, weld shape, and size can be achieved.
In addition, the laser welding machine is equipped with various safety devices and protective measures to ensure the safety of operators and the stable operation of the equipment. For example, equipment usually has protective covers, emergency stop buttons, and other devices to prevent laser radiation from causing harm to personnel, and to quickly cut off the output of the laser beam in emergency situations.
In summary, laser welding machines use high-energy laser beams to melt and weld workpieces, achieving efficient and accurate welding processes. Its working principle is based on the characteristics of the laser beam, and through precise control systems and safety devices, it ensures welding quality and operational safety.
