Laser welding is a relatively advanced welding technology at present, which is beyond doubt. Laser welding technology has gone beyond the traditional welding method and has begun to be widely used and developed in China. Compared with traditional welding machines, it has many advantages. Laser welding has a higher degree of automation and a simpler welding process. The workpiece processed by laser welding not only has a beautiful appearance, small welds, large welding depth, high welding quality, but also greatly improves welding efficiency. Let's look at the industries where laser welding is widely used.
 

Which industries have more applications of laser welding technology?

1. Automobile manufacturing

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

The laser welding machine is non-contact processing, which is pollution-free and fast, and is more suitable for the production process requirements of high-end automotive consumer products. The automobile made of laser welded aluminum alloy is formed by laser welding thin aluminum alloy, which not only greatly reduces the weight of the vehicle body, but also reduces the process of manufacturing the automobile, improving production efficiency, and is welcomed by the majority of automobile manufacturers. In addition, medium and low power pulsed laser welding is also widely used in the welding of automotive components, such as cylinder head gaskets, oil nozzles, and spark plugs.

Power batteries account for 30% to 40% of the cost of new energy vehicles, making them 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 structure of power batteries contains a variety of materials, such as steel, aluminum, copper, nickel, etc. These metals can be made into electrodes, wires, or shells. Therefore, whether it is welding between one material or multiple materials, laser welding can perfectly utilize the excellent directionality and high power density of the laser beam to work. The advantage of laser welding lies in new energy power batteries. The industry has reached its peak!

2. Electronics

Laser welding machines do not generate mechanical extrusion or mechanical stress, so they particularly meet the processing requirements of the electronic industry. For example: welding of transformers, inductors, connectors, terminals, fiber optic connectors, sensors, transformers, switches, mobile phone batteries, microelectronic components, integrated circuit leads, etc.

In the development of vacuum equipment, laser welding has also been applied. The thickness of elastic thin-walled corrugated plates in sensors or temperature controllers is 0.05-0.1mm, which is difficult to solve by traditional welding methods. TIG welding is easy to weld through and has poor plasma stability, which is affected by many factors. Laser welding has good results here.

3. Biomedicine

Laser welding of biological tissues began in the 1970s. The successful welding of fallopian tubes and blood vessels using laser welding and its demonstrated advantages have led more researchers to attempt to weld various biological tissues and extend it to the welding of other tissues. The research on laser welding of nerves at home and abroad mainly focuses on the research of laser wavelength, dose, function recovery, and the selection of laser solder. Compared with traditional suture methods, laser welding has the advantages of fast anastomosis speed, no foreign body reaction during the healing process, maintaining the mechanical properties of the welding site, and the repaired tissue growing according to its original biomechanical properties. It will be widely used in future biomedical applications.

4. Jewelry

Jewelry is precious and exquisite. Laser welding machines magnify small parts of jewelry through a microscope, achieving precision welding without deformation after repair, solving two major problems of weld beauty and welding quality, and becoming indispensable welding equipment.

The above are several industries where laser welding technology is widely used. In addition to these, laser welding technology also plays an important role in many industries such as aviation, hardware and building materials, and machinery manufacturing. In recent years, with the increasingly mature digital technology, digital welding machines and digital control technology have gradually entered various industries. The development of research and automation technology in various disciplines has promoted the progress of welding automation, especially the development of numerical control technology, weld tracking system, and information processing technology, which have led to revolutionary changes in laser factory.
