Laser Welding: Diversification of Application Scenarios

May 24, 2022


Due to the advantages of laser welding technology in aluminum alloys, magnesium alloys, copper alloys, nickel alloys, titanium alloys and other metal materials, laser welding technology gradually replaces traditional welding processes, which accelerates the application of laser welding in batteries, bathrooms, new energy vehicles and its zero The application layout of accessories, hardware, jewelry, 3C and other fields, and due to the maturity and breakthrough of laser soldering and laser plastic welding in recent years, this will further expand the application scenarios of laser welding, such as communication electronics, medical equipment, Automotive electronics and sensors, etc. ‍


1. The advantage is the potential, the most promising advanced welding technology

First of all, in terms of efficiency, laser welding is 2-10 times faster than traditional welding. The laser welding machine adopts the processing principle of laser beam irradiation, which is very fast in processing speed, and the welding penetration is relatively deep.

Secondly, in terms of welding quality, laser welding is better. Due to the small heat-affected area during welding, the workpiece has no deformation, no welding scar, firm welding, smooth and beautiful, and the subsequent grinding process is reduced, and the welding yield is high. The laser welding machine can weld metal materials such as stainless steel plates, iron plates, galvanized plates, etc., and can weld various dissimilar materials together.

In addition, it has high operability (low manual technology content) and is easy to automate. At the same time, it is safe and environmentally friendly. Welders can say goodbye to traditional welding sites such as wearing insulating shoes and thick gloves, while holding a protective mask and heavy welding tongs. .

‍2. What are the technical difficulties of laser welding?

Marking, cutting and welding are the three most important applications in laser processing. Among them, laser marking and cutting started early, but in recent years, with the rise of new energy vehicles and the vigorous development of downstream power battery industry, automatic welding equipment demand is growing rapidly. This has led to the development of the laser welding industry.

However, its development speed is not as fast as the field of fiber cutting and marking, which involves the biggest feature of laser welding equipment: high customization, customers have many needs for products, so it is difficult to achieve large-scale mass production - different Different products, different application scenarios, different strength requirements, the requirements of the process and fixture used by the laser welding machine are different, and almost every application requirement requires customized products.

3. The future of laser welding technology can be expected!

After years of development, laser technology has become widely known, and people's recognition of it has increased, which has promoted the application of laser technology. At present, laser welder machine can be divided into laser composite heat source welding equipment for structures with medium thickness and above, laser welding equipment for thin metal materials; laser welding machine for high-reflection and low-absorbing materials; precision laser welding equipment for transparent materials, etc.

At present, the application process of laser welding in the automotive industry (such as laser tailor welding of unequal thickness plates) and the power battery industry (such as explosion-proof valve sealing welding) is relatively mature.

At the same time, laser welding technology has gradually been widely used in the manufacture of aerospace equipment, especially the manufacture of weapons and aircraft, the manufacture of thin-walled parts, and the assembly of fuselage accessories. Laser welding technology is indispensable. The application of laser welding technology improves the structural performance of the aircraft and reduces the quality of the substrate.

In addition, laser welding technology was introduced into the shipbuilding industry and quickly replaced traditional welding technology, improving welding efficiency and quality. Whether from thin plate welding to medium plate welding, or the penetration of new materials and new applications, there are too many technologies in the field of laser welding to be studied, and there is still a huge room for improvement in the application penetration rate in the manufacturing industry.
