A laser welding machine is a machine 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?

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.

Therefore, whether it is welding between one material or between multiple materials, laser welding can perfectly take advantage of the excellent directionality and high power density of the laser beam to work. The advantage of laser welding lies in the new energy power battery. The industry is at its peak!

• 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 an automatic workbench can weld beautiful lithium and aluminum batteries efficiently and environmentally.

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.

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, the plasma stability is not good, and there are many influencing factors. Laser welding works well. It is widely used.
