A laser welder, also often referred to as a laser welder or laser welder, 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 is diffused into the material by thermal conduction, causing the material to melt to form a specific molten pool. So, which industries are laser welding machines mainly used in?

1.Battery industry         

• 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 production process of power batteries, from 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 can be made into electrodes, wires or casings.

• Batteries for digital products such as mobile phones

The batteries of cell phones and most coding products are laser welded. Laser welding machine combined with automatic workbench can weld beautiful lithium and aluminum batteries efficiently and environmentally.

2.Automobile manufacturing

Welding machines are often used in the automotive industry. Due to the large size 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 non-contact processing, which is pollution-free and fast, and is more suitable for the production process needs of high-end automotive consumer products. Automobiles made of laser-welded aluminum alloys are formed by laser-welding thin aluminum alloys, which not only greatly reduces the weight of the body, but also reduces the process of manufacturing automobiles and improves production efficiency, which is welcomed by the majority of automobile manufacturers.

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

3.Electronic and electrical industry           

Since laser processing is a non-contact processing method, the laser welding machine does not produce mechanical extrusion or mechanical stress, so it is particularly suitable for 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.

Due to the small heat affected zone, fast heating concentration and low thermal stress, laser welding shows unique advantages in the packaging of integrated circuits and semiconductor device casings.

In the development of vacuum equipment, laser welding has also been applied. The thickness of the elastic thin-walled corrugated plate in the sensor or thermostat is 0.05-0.1mm, which is difficult to solve by traditional welding methods. TIG welding is easy to penetrate, and the plasma stability is not good, and there are many influencing factors. Laser welding works well. It is widely used.

4.Jewelry Industry

Due to the high precision of laser processing, it is very suitable for precious small products in the jewelry industry. Because the laser focused beam is extremely thin, it can be enlarged through a microscope to enlarge the small part of the jewelry to achieve precise welding. The connection of the jewelry chain and the setting of the gemstones need to be done with a laser spot welder. Laser spot welding machine is a must-have equipment.

5.Home building materials industry

• Building materials industry

Laser welding precision has good appearance, so it has a wide range of applications in laser marking and laser welding of high-end sanitary stainless steel products. Such as: handles, faucets, stainless steel tableware, knives, etc., laser marking is often used to make corporate LOGO, and the sealing of high-end electric kettles is also completed by laser welding.

• 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, repair and modification during mold making and use. Laser welding perfectly solves the two major problems of weld beauty and welding quality.

•  Lighting industry

In the lighting industry, due to the complexity of the shape and structure of the lighting, there are many hard-to-reach parts that cannot be welded by ordinary welding machines, and the effect after welding must be guaranteed. Handheld laser welding machines have exactly this function. The welding angle can be moved at will to achieve better welding effect and break the space limitation of traditional welding.

 6.Mould and machinery manufacturing

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 non-contact processing, laser processing is especially suitable for molds and high-precision machinery manufacturing industries, such as plastic molds, rubber molds, stamping molds, casting molds, etc.  Forging dies, precision repair of wire drawing dies.

This laser welding repair technology can not only be used to repair mold wear, but also achieve precise welding of small and precise areas without deformation and pores after repair.
