Laser welding machine is a new type of welding equipment that uses laser beams for welding, with the characteristics of high precision, high efficiency, and high quality. Laser welding machines are widely used in fields such as aerospace, automotive manufacturing, electronics, medical equipment, and mechanical manufacturing.
The working principle of a laser welding machine is to use the high energy and high focusing of the laser beam to heat the welding material to a molten state, then cool and solidify, thereby completing the welding work. Compared with traditional welding methods, laser welding can obtain higher welding quality and smaller Heat-affected zone, without the use of welding auxiliary materials, and will not pollute welding materials, so it is widely used in many fields.
The main components of a laser welding machine include a light source, optical system, welding station, gas protection system, etc. The light source is the most critical component of laser welding machines, and currently commonly used light sources include CO2 lasers, fiber lasers, semiconductor lasers, etc. Different light sources have different advantages and disadvantages, and it is necessary to choose a suitable light source based on specific welding needs.
The optical system is a key component that focuses the beam of light onto the welding point, consisting of a lens group, a reflector group, a focal length adjuster, and so on. The quality of optical systems directly affects the welding effect and accuracy.
The welding table is a component used to fix the workpiece and needs to have stable and reliable performance. The gas protection system is mainly used to protect the molten pool from oxygen pollution during the welding process, preventing oxidation and damaging the quality of the weld seam.
The advantages of laser welding machines lie not only in their high accuracy and quality, but also in their ability to automate production. Automated production can greatly improve production efficiency, reduce manual intervention, and reduce labor costs.
Laser welding machines have a wide range of applications, mainly in the following areas:
- Aerospace field: Laser welding machines can be used to achieve precision welding of aircraft engine parts and aerospace components, improving the overall process level.
