2. Optical system: The optical system is used to guide, focus, and control the transmission direction and focal length of the laser beam, typically including lenses, mirrors, focal length adjusters, etc. A high-quality optical system ensures the stability and precision of the laser beam.
3. Worktable: The worktable is the working platform of the laser welding machine, used to place and clamp the workpieces to be welded. The worktable usually has a multi-axis motion control system for precise positioning and movement of the workpieces.
4. Control system: The control system is the intelligent core of the laser welding machine, including hardware and software components. The control system can monitor and adjust laser parameters, optical systems, worktable movements in real-time, ensuring the accuracy and stability of the welding process.
5. Gas protection system: During the laser welding process, inert gases (such as argon) or reactive gases (such as oxygen) are typically used to protect the welding area, preventing oxygen or other impurities from affecting the welding quality.
6. Cooling system: Laser welding machines generate a large amount of heat during operation, requiring a cooling system to effectively dissipate heat from the laser source, optical system, and other components, ensuring long-term stable operation of the equipment.
These are the main core components of a laser welding machine, which work closely together to complete the laser welding process, achieving efficient and precise welding operations. High-quality laser welding machines, based on these core components, can achieve more efficient and precise welding results through precise design and intelligent control, meeting various welding requirements.
