Applications of Laser Welding

2024-09-06

Laser welding technology is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It has the advantages of fast welding speed, large welding depth, small welding deformation, high degree of automation, and the ability to perform non-contact long-distance welding. The following are the applications of laser welding in multiple fields:

Manufacturing industry

1. Automotive parts manufacturing: Laser welding plays an important role in the automotive manufacturing industry, especially in the lightweight manufacturing of automotive parts such as automotive powertrain modules, chassis modules, body modules, and electronic systems. Laser remote welding technology, laser-arc hybrid welding technology, laser tailor-welded blank technology, laser wire filling welding and laser brazing and other laser welding technologies play an important role in improving product quality and realizing lightweight manufacturing of automobiles.

2. Microelectronics industry: The microelectronics industry has very high requirements for welding processes. With its characteristics of fast heating speed, small heat-affected zone, high weld quality, and high degree of automation, laser welding is widely used in the manufacturing of electronic components, circuit boards, and electronic equipment. Laser welding technology can achieve high-speed, high-stability, and high-integration interconnection and packaging, and is suitable for the welding of products such as optical communication components and sensors.

Powder metallurgy

Laser welding also has certain applications in the field of powder metallurgy, such as for the welding and repair of powder metallurgy parts. Through the high-energy-density heating of the laser beam, powder metallurgy parts can achieve rapid melting and connection, improving the strength and durability of the parts.

Biomedicine

In the field of biomedicine, laser welding technology plays an important role in the manufacturing of medical devices with its characteristics of high precision, high efficiency, and low impact. Especially in the manufacturing of complex medical interventional devices such as heart stents and vascular interventional guidewires, laser welding technology can ensure a flat and beautiful weld seam while retaining the fine structure and excellent properties of the material.

Other fields

1. Aerospace: China's laser welding technology is at the world's advanced level and has been successfully applied to the prototypes and product manufacturing of multiple domestic aerospace research projects. Laser welding can meet the welding requirements of high strength and high precision of materials in the aerospace field.

2. New energy: In the field of new energy, laser welding technology is widely used in the manufacturing of solar panels and the welding of electric vehicle batteries. Laser welding can achieve non-contact processing, reduce material loss and pollution, and improve production efficiency and product quality.

3. Home appliance industry: In the home appliance industry, laser welding technology is used for welding parts such as the shell and internal structure of home appliance products. Laser welding can achieve fine welding effects and improve the appearance and performance of products.

In short, laser welding technology has been widely used in multiple fields with its unique advantages. With the continuous progress and innovation of technology, its application range and prospects will be even broader.
