Working principle of laser welding machine

The laser welding machine is a welding equipment with laser as the core device. The laser is produced by the laser. The characteristics of the laser light source mainly include good monochromaticity, good directivity, and high brightness. It is a Hot working process that uses the laser beam to convert into a high-energy heat source to melt and weld the workpiece surface.



The working principle of the laser welding machine is to convert the laser beam into a laser beam through a converter, and then irradiate it on the surface of the workpiece to be welded. When the laser beam contacts the workpiece surface, it will generate a high-energy heat source and melt the surface. During this process, the generated high-temperature environment can melt and weld two or more workpieces together, including the welding of various materials such as metals and plastics.



Composition of laser welding machine

1. Laser welding host: The laser welding host is composed of power supply, laser, optical path and control system to provide the energy required for welding processing.



2. Cooling system: the cooling system is a device used to cool the heat, mainly to ensure the stability and service life of the laser welding machine, especially the high-power machine, working in a high temperature environment for a long time.



3. Fixture: Fixture is generally a tool used to fix welding during welding operations, especially in batch production, which is one of the essential equipment that directly affects production efficiency.



4. Workbench: The workbench refers to the active laser welding workbench, which is designed to enable the laser beam to move according to specific requirements and welding operation trajectory, so as to realize the automatic welding function.



5. Observation system: The laser welding machine is generally equipped with an observation system, which can conduct real-time observation on the ongoing welding operation, which is conducive to accurate positioning and inspection of welding effect.


Advantages of laser welding machine

1. Excellent welding quality: narrow weld width, small heat affected zone, able to reduce thermal deformation, avoid problems such as pores and cracks, and ensure more stable welding quality.



2. Efficient welding efficiency: It can achieve rapid welding, shorten welding time and production cycle, and reduce production costs.



3. Convenient operation: the laser welding machine is highly intelligent, simple to operate and easy to master.



4. Environmental protection and energy saving: compared with traditional welding equipment, laser welding machine can realize non-contact welding without harming the environment and human body.
