Laser Welding Machine Assists In Automobiles Lightweight Development

December 7, 2023

Laser welding machine is an efficient and precise welding method that uses a high-energy density laser beam as a heat source, and is one of the important aspects of the application of laser material processing technology. At present, with the adjustment of energy structure and the improvement of environmental protection requirements, the automotive industry is developing towards lightweight. The use of new lightweight materials is one of the effective means to achieve automotive lightweight. Laser welding machine with its unique advantages, plays an increasingly important role in connecting lightweight materials.

Automobile lightweighting is not literally understood as "reducing automobile weight". However, in order to ensure the quality of automobiles, more new materials are applied to functional and structural components, making the performance of automobile components more excellent. At the same time, the weight is lighter, ensuring that energy consumption is reduced during driving, achieving multiple effects.

At present, the lightweight technology of automobiles is mainly achieved through the following ways.

1.The proportion of lightweight materials continues to rise, with applications such as aluminum alloys, magnesium alloys, titanium alloys, high-strength steel, plastics, powder metallurgy, ecological composite materials, and ceramics.

2.The level of structural optimization and modular design of components is constantly improving, such as using front wheel drive, high rigidity structure, and ultra-light suspension structure to achieve lightweight goals.

3.The development of computer-aided integration technology and structural analysis technology; Enable the automotive manufacturing industry to continuously innovate in forming methods and connection technologies.

Among the three ways to achieve automotive lightweight mentioned above, laser cutting machine and laser welding machine have become important technical means for achieving automotive lightweight due to their unique advantages.

As for laser welding machine, they are non-contact and can achieve precision welding without touching the product during the processing. However, traditional connection methods, some rely on screws for fastening and others rely on adhesive connection, cannot meet the requirements for precision and robustness in modern automobile manufacturing, and traditional methods are also not suitable for connecting new materials. In contrast, laser welding machine have achieved significant technological advancements in the robustness, seamless, precision, and cleanliness of connections, and will become an important forming method in the future.
