Laser welding machine, also often called laser welding machine or laser welding machine, is a machine used for laser material processing. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. So, which industries are laser welding machines mainly used in? Today, Dato Laser Manager summarized the six major industries to share with everyone.

1. Battery industry

A. New energy vehicle power battery

Power batteries account for 30%-40% of the cost of new energy vehicles, and are the largest part of the cost of new energy vehicles. In the process of power battery production, from battery cell manufacturing to PACK assembly, welding is a very important manufacturing process. In particular, the power battery structure contains a variety of materials, such as steel, aluminum, copper, nickel, etc. These metals may be made into electrodes, wires or shells.

Therefore, whether it is welding between one material or between multiple materials, laser welding can make perfect use of the excellent directionality and high power density of the laser beam to work. The advantage of laser welding is in the new energy power battery. The industry has played to its fullest!

B. Batteries for mobile phones and other digital products

The batteries of mobile phones and most code products are laser welded. The combination of laser welding machine and automatic workbench can efficiently and environmentally weld beautiful-looking lithium batteries and aluminum batteries.

2. Automobile manufacturing industry

Welding machines are often used in the automotive industry. Because of the large volume and high degree of automation in the automotive industry, laser welding equipment will develop in the direction of high-power and multi-channel.

The laser welding machine is a non-contact processing, no pollution to the product, high speed, and more suitable for the needs of the production process of automotive high-end consumer products. Cars made of laser-welded aluminum alloys are formed by laser welding thin aluminum alloys, which not only greatly reduces the weight of the car body, but also reduces the process of manufacturing cars, improves the production efficiency, and is welcomed by the majority of the automobile manufacturing industry. Favor.

Moreover, low- and medium-power pulsed laser welding is also widely used in auto parts, such as the welding of cylinder head gaskets, oil nozzles, and spark plugs.

3. Electronics and electrical appliances industry  

Since laser processing is a non-contact processing method, the laser welding machine does not produce mechanical extrusion or mechanical stress, so it particularly meets the processing requirements of the electronics industry. Such as: welding of transformers, inductors, connectors, terminals, fiber optic connectors, sensors, transformers, switches, mobile phone batteries, microelectronic components, integrated circuit leads, etc.    

Because laser welding has a small heat-affected zone, rapid heating concentration and low thermal stress, it has shown unique advantages in the packaging of integrated circuits and semiconductor device housings.

In the development of vacuum devices, laser welding has also been applied. The thickness of the elastic thin-walled corrugated sheet in the sensor or thermostat is 0.05-0.1mm, which is difficult to solve with traditional welding methods. TIG welding is easy to weld through, plasma stability is not good, and there are many influencing factors. Laser welding has a good effect. It is widely used.

4. Jewelry industry

Due to the high precision of laser processing, it is very suitable for precious and small products in the jewelry industry. Because the laser focused beam is extremely thin, it is magnified by a microscope, and the small parts of the jewelry are magnified to achieve precise welding. The connection of jewelry chains and the inlay of gems should be completed with laser spot welding machine.Laser spot welding machine is a necessary equipment.

5. Household building materials industry

A. Building materials industry

Laser welding precision has a good appearance, so it has a wide range of applications in laser marking and laser welding of high-end bathroom stainless steel products. Such as: handles, faucets, stainless tableware, knives, etc., which mostly use laser marking to make corporate LOGO, high-end electric kettles and other seals are also completed by laser welding.

B. Kitchenware industry

In the kitchenware industry, a large number of sheet metal parts need to be welded. For example: group welding and butt welding of kitchen utensils and tableware, repair and modification during mold making and use. Laser welding perfectly solves the two major problems of weld beauty and welding quality.

C. Lighting industry

In the lighting industry, due to the complexity of the shape and structure of the lighting, there are many inaccessible parts that cannot be welded with ordinary welding machines, and the effect after welding must be ensured. The hand-held laser welding machine just has this feature. It can move the welding angle at will to achieve a better welding effect and break the space limitation of traditional welding.

6. Mould and machinery manufacturing industry

The most typical example of the application of laser welding in the mold industry is the mold repair laser welding machine. Due to the obvious advantages of using non-contact processing methods, laser processing is particularly suitable for molds and high-precision machinery manufacturing industries due to its fineness and less impact on materials, such as plastic molds, rubber molds, stamping molds, casting molds, forging molds, Precision repair of drawing die.

This laser welding repair technology can not only be used to repair mold wear, but also can achieve precise welding of small and precise areas, and there will be no deformation or pores after repair.

 

In addition to the above-mentioned main application industries, laser welding machines are also used in military, aerospace, hardware, tools, instruments, sanitary ware, energy lighting and other industries.

At present, laser welding equipment has penetrated into our lives and has become more and more widely used, gradually replacing traditional welding methods. And the welding speed is 5 to 10 times that of the traditional welding machine. Especially suitable for mass production. For more information, please contact Dato Laser!
