The principle of laser welding machine

A laser welding machine is a machine used in material processing laser welding. The laser radiation heats the surface of the workpiece, diffuses into the workpiece through heat conduction, and melts it to form a specific molten pool.

Types of laser welding machines

Automatic laser welding machines include automatic laser welding machines and manual laser welding machines.

Automated laser welding machines use high-energy laser pulses to locally heat materials in tiny areas and form specific molten pools. It is mainly aimed at the welding of thin-walled materials and precision parts and can realize spot welding, butt welding, stitch welding, sealing welding, etc. The welding effect has no porosity, high positioning accuracy, and high efficiency.

The manual laser welding machine can perform laser welding of long-distance and large workpieces. The heat-affected area of the workpiece is small, which will not cause deformation and blackening of the workpiece, the welding effect is firm, and there is no depression at the junction of the substrate.

Application of laser welding machine

Laser welding machines can replace traditional welding equipment. The application scenarios are as follows,

1. Power battery industry

From cell manufacturing to pack assembly, we can see that the power battery structure contains a variety of materials, such as steel, aluminum, copper, nickel, etc. The welding between various materials can use laser welding machines for efficient, flexible, and high-power welding work.

2. Automobile manufacturing industry

The laser welding machine can efficiently handle the welding work of aluminum alloy, reduce the weight of the car body and improve production efficiency.

3. Aerospace Manufacturing

The welding work of different materials inside aerospace tools is more efficiently done by laser welding machines, and there is no workpiece deformation, etc., and the welding effect is ideal and extremely stable. Laser welding machines weld oxygen tanks, fuel tanks, and other components.

4. Jewelry industry

the Due to the high precision of laser processing, spot welding is often used. Laser welding equipment is precisely positioned, and suitable for fine processing and precision welding of high-value jewelry. The joints of the jewelry chain and the setting of the gemstones need to be completed with a laser spot welding machine.

5. Electronic industry

The wall thickness of electronic devices is generally very thin, and the laser welding machine perfectly replaces the traditional welding method, eliminating the disadvantages of TIG penetration. For example, welding work of materials for precision instruments such as mobile phones and laptop computers.

6. Furniture and building materials industry

Kitchen supplies, bathroom stainless steel products, tableware, and props require laser marking of corporate logos, and laser welding technology is often used for sealing joints. The welding effect is firm, which ensures the durability of the product.

7. Mold industry

Due to the fineness of the laser welding machine, the workpiece is not deformed. It is widely used in plastic mold, rubber mold, stamping mold, casting mold, forging mold, and other industries.

Customers can customize the automatic welding equipment according to the actual production process requirements, and the equipment configuration has a large room for change. As an excellent laser equipment manufacturer, NORMALTAN CHINA will continue to improve itself and sincerely provide you with various welding solutions.
