Principle of laser welding machine
The laser welding machine uses the huge energy of laser pulse to heat the materials to be processed in a small range, and finally melts them to form a specific molten pool, which can realize spot welding, butt welding, overlap welding, seal welding, etc. It has opened up a new application field of laser welding with its unique advantages, providing precision welding for thin-walled materials and micro parts.
Application of laser welding machine
1. Welding
The main purpose of the laser welding machine is undoubtedly welding. It can not only weld thin wall metal materials such as stainless steel plates, aluminum plates and galvanized plates, but also be used for welding sheet metal parts, such as kitchen appliances. It is suitable for welding flat, straight, arc and arbitrary shapes. It is widely used in precision machinery, jewelry, electronic components, batteries, clocks, communications, handicrafts and other industries. It can complete welding well in various complex environments, It has higher production efficiency and more obvious advantages than traditional argon arc welding, electric welding and other processes.
With laser welding machine, the weld width is small, the depth is large, the thermal shock area is small, the deformation is small, the weld is smooth and beautiful, the welding quality is high, there is no air hole, it can be accurately controlled, the welding quality is stable, and there is no need for treatment or simple treatment after welding.
2. Patching
The laser welding machine is not only used for welding, but also can repair the wear, defect, scratch of the mold, as well as the sand hole, crack, deformation and other defects of the metal workpiece. The mold will be worn after being used for a long time. If the mold is discarded directly, it will lose a lot. The defective mold can be fully used again by repairing through the laser welding machine. Especially when repairing the fine surface, the two processes of thermal strain and post welding treatment are avoided, greatly saving the production time and cost.
3. Cutting
Laser cutting is a new cutting method. The laser welding machine can be used to cut stainless steel, copper, aluminum, zirconium and their alloys. In addition, it can also cut non-metallic materials such as plastic, rubber, wood, etc. It is another important application of laser welding machine in material processing.
4. Cleaning
With the continuous reform and upgrading of the laser welding machine, it has more and more functions. It can not only weld and cut, but also clean and remove rust. The laser welding machine uses the beam emitted by the laser to remove the pollution layer on the surface of the workpiece to be treated. The laser welding machine is used for cleaning, which is non-contact and does not require cleaning fluid, so it can replace professional cleaning equipment.
